Hoyas in the DG Plant Files

After some discussion on this thread http://davesgarden.com/community/forums/t/987006/ I volunteered to start up (and moderate if needed) a thread on Hoyas in the DG Plant Files. I am going to repeat what I said there in my next post here, then I am going to post a list of the existing Hoya pages on DG. After that, we can throw this thread open for comment etc.

Here are the existing Plant Files rules -

1) All species must be recognized and cited within the American Horticultural Society or Royal Horticultural Society encyclopedias; Hortus Third, or the Germplasm Resources Information Network (GRIN) database) at ars-grin.gov, the Missouri Botanical Garden's MOBOT.org site, or other standard reference materials or websites.

2) All cultivars must be registered with an International Cultivar Registration Authorities (ICRA) designated registry (if one exists for the genus); or they should be patented or trademarked.

3) Cultivars (and species, subspecies, forms and varieties) that cannot meet the second criteria must be widely available on a commercial or passalong basis, with references (citations) in other databases or reference materials. A single reference (especially when it's the hybridizer, eBay seller or vendor) is not adequate to establish the plant's legitimacy.

We use these criteria to make sure PlantFiles can serve as a reliable reference for readers to look up and identify plants. Allowing entries for unnamed seedlings or unverifiable names will undermine the accuracy and overall helpfulness of PlantFiles.

Clearly this does NOT allow for the posting of Hoyas which are yet to be formally named eg. H. aff. ... H. sp. ... etc.
The only way to get such plants accepted is to fit the third criterion above

Here is my original response on this topic, from the earlier thread -

Hi All,
I put a fair bit of stuff on Plant Files, but I too have many plants which cannot be listed. The problem is that the plants you have as specialist collectors are coming from wild collected material either from a location, e.g. H. sp. Philipines; a specific collector DL#### or are plants that are only partially identified e.g. H. aff. clandestina. The purpose of Plant Files is to list plants which have already been FORMALLY named in some fashion - either botanically (e.g. Hoya linearis) or as named cultivars such as Hoya carnosa 'Krinkle-8'. It is not a completely unreasonable attitude for the PF editors to take - to do otherwise would be to inundate the Plant Files with "Auntie's Rose Bush" type plant names with little or no validity.

What you can do, as a first step, is look at all the Hoya listings which already exist (there are 226 as I type) and make sure those are correct. If there are any which need fixing go through the "report an error" process to do that. I'll give an example: http://davesgarden.com/guides/pf/go/57706/ is listed as Hoya carnosa 'Picta' this looks like Hoya carnosa 'Rubra' (Krimson Princess) to me: I don't know the carnosa varieties well enough to be sure of that but I'll bet you guys do! If these ARE two different plants a note on how to distinguish them is a good idea on each of the Plant file pages.

Secondly, the existing list needs to be checked to see if there are any known named species, subspecies or varieties
which are missing from the PF list. Also any synonyms need to be taken into account, especially if they are commonly seen on plants for sale. The best resource to check for published botanical names online is IPNI - if a plant name is in IPNI it should be in Plant Files, unless that name has become a synonym, in which case the name should be in the listed synonyms for that plant. Already recognised cultivars can be checked at the RHS search site though even that seems very lacking to me as of this date. Often it requires correspondence and scholarship to track down the details required, but sometime that is half the fun.

As far as I know there is NO "International Cultivar Registration Authorities (ICRA) designated registry" for Hoyas because the genus has not been that heavily hybidized as yet. There are very few registered hybrids let alone "patented or trademarked" cultivars! - I know Carol (AlohaHoya) has at least one registered hybrid.

The group of interested growers here on DG and elsewhere are right at the forefront of the development of Hoyas as
a viable group of horticultural plants. It is in our own interest to be as active as possible and to get the Plant Files Hoyas as good as they can be. If we cannot as yet find a way to add all the plants we would like to, don't worry, time will tell. In the meantime let's see if we can get as much done within the existing framework. Plant Files CAN be modified, Dave has explicitly said so, it is just a question of there being enough plants to justify doing so. A recent example of this is the addition of the Grex field for the use of Orchid growers.

Here are a couple of links to get you started -

I hope this has been of use

Ok,
that's it from me for now. I am throwing this thread to the winds for general comment.

One thing though, in order for me to keep track, could you PLEASE DMAIL me with any info regarding a specific plant or species - I would rather keep this thread for general comments and ideas of what we want to try and do with the Plant Files.

As an example, I'll start with this idea, which seems like a no brainer to me.

Common Names: Most Hoyas don't have one, so their Common name field in Plants files usually says "Hoya" and nothing else. It seems to me that the Commonest generic term for Hoya is "Wax Plant", so maybe "Wax Plant" needs to be added to all the Hoya pages where it isn't at present. That way, any one who searches for "Wax Plant" will get the full impact of the genus instead of the measly 23 species the term currently brings up. I await your comments on this idea.

Ciao, KK.

KK: Another common name is "Porcelain Flower" ... 6 listings in PF under that heading: http://davesgarden.com/guides/pf/adv_search.php?searcher%5Bcommon%5D=porcelain+flower&searcher%5Bfamily%5D=&searcher%5Bgenus%5D=&searcher%5Bspecies%5D=&searcher%5Bcultivar%5D=&searcher%5Bhybridizer%5D=&searcher%5Bgrex%5D=&search_prefs%5Bblank_cultivar%5D=&search_prefs%5Bsort_by%5D=rating&images_prefs=both&Search=Search

When I first joined DG I had a hard time finding a lot of plants in PF until someone told me it is best to search by Genus name, so that's how I always search now, but sometimes if you don't know the genus name you won't always find the plant you are searching for. I agree that "Wax Plant" should be listed for all Hoya's in the data base.

Great ideas! Will start thru the plant files...maybe do 5 to 10 a night...maybe more. It's important to check the picture to the 'real' one (whatever that means these days). Do you think it important to explain the controversy over a name....?

Carol

Took me shorter than I thought...KK...loooooooong email coming your way.

Hi Carol,
Re "controversy over a name" it rather depends on the nature of the controversy I think! We can probably have a look at those kinds of things on a collective basis as they come up - more heads and all that! I mean this is NOT going to be a short process - I want to give all of the forum members who have opinions a chance to participate, get some sort of consensus amongst us and THEN dMail admin with any needed changes, probably on a one plant at a time basis. I don't mind doing the dMails - I have sent them 18 Plant Files corrections in the last month as it is, and that is just stuff I have randomly come across while doing my own research - (just for interest they have accepted 16 of those straight of the bat, I have retracted one due to a misunderstanding, and I am still looking for supporting evidence to get the last one through) so it can be done.

Ciao, KK.

PS. Looking forward to the "loooooooong email.." LOL!

Thank you all for taking this on. I am watching this thread. When you are going through the entries and find errors or omissions that you cannot add yourself, please use the red 'Report an Error' button in the upper right hand corner of the PlantFile entry in question and tell us what the error is. If you have some links to websites that verify this, then the correction would be much quicker, as we don't have to spend so much time researching it.

I'm watching and more than willing to help get the Hoya portion of the database as complete as possible. If it's something that I can do, I'll help in any way I can. If it's something that I can't do, I'll forward the request on to those that can.

Welcome Aboard Joan,

If you are really bored today, how about adding "Wax Plant" and "Porcelain Flower" to all the common name fields? LOL!

Ciao, KK.

Edited to add: I am off to the garden for the rest of the afternoon (I have about 3 hours of daylight left to plant a couple of thousand (not a joke, unfortunately) baby Ixia spawn into pots) I'll check in later tonight after it gets dark.

I can do that tomorrow. I think it's your morning, but it's nearing midnight for me. :) So, consider it to be done by noon tomorrow my time.

HI All,
It has taken me a few days to get back to the project (life got in the way) but I have finished going through all the Hoya names beginning with A. That threw up a few surprises for me, and I want to run a few things past the rest of you.

Firstly, how many of you are aware of Kloppenberg and Gildings publication of Eriostemma as a separate Genus in 2001?

IPNI lists the following publications -

Eriostemma (Schltr.) Kloppenb. & Gilding -- in Fraterna 14(1): 14 (2001). ; nom. inval. (IK)
Eriostemma (Schltr.) Kloppenb. & Gilding -- in Fraterna 14(2): 1 (2001). (IK)
Eriostemma affinis (Hemsl.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma ariadna (Decne.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma ciliata (Elmer ex C.M.Burton) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma coronaria (Blume) Kloppenb. & Gilding -- in Fraterna 14(2): 1, 4 (2001). (IK)
Eriostemma gigas (Schltr.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma guppyi (Hemsl.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). ; nom. inval. (IK)
Eriostemma hollrungii (Warb.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma lauterbachii (K.Schum.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). ; nom. inval. (IK)
Eriostemma lutea (Kostel.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma madulidii (Kloppenb.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma neoguineensis (Engl.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma peekelii (Markgr.) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma pulgarensis (Elmer) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). ; nom. inval. (IK)
Eriostemma purpurea (Blume) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)
Eriostemma velutina (Wight) Kloppenb. & Gilding -- in Fraterna 14(2): 4 (2001). (IK)

I don't have access to Fraterna so it would be good if someone who does could have a look at the actual article and perhaps summarize their reasoning for the rest of us. Meanwhile, how do the rest of you feel about this idea. I've never had any Eriostemmas myself, but I gather from those of you who do grow them, that they are quite distinctive in their behaviour and cultural requirements. I am a bit concerned with the "nom. inval." tags on some of the IPNI Listings - it looks to me like someone got a bit sloppy (apparently by failing to cite the Basionyms correctly) The Kloppenberg and Gilding article was published far enough back in time that I am sure all the experts have had a chance to think about it and form an opinion.

Our options, as far as the Plant Files entries go, are three

1/ Ignore it
or
2/ Add the Eriostemma .. names as Synonyms on the appropriate pages
or
3/ Change the head of the listings to Eriostemma.. and add the Hoya .. names as synonyms.

This is fairly major stuff, so I want to see as many opinions as possible before I take this up with Admin.

I have some other things to mention but I think I'll put them in separate posts, that way we can refer to the post numbers when discussing stuff. (Do all of you know you can tag individual posts, not just whole threads? In Firefox, right-click on the post number to open it on its own tab, then click the little yellow folder and create your tags for that post only - very handy)

TTFN, KK.

KK....

Mark Randal wrote a long detailed article about that same subject in STEMMA last issue...if you go to www.stemmajournal.com you can find it. Regardless of the article, the world of hoyas still seems split on the separation of Eriostemmas from Hoyas...

There are more controversies about hoya ID than there are people to disagree.... I, personally, will wait until more people who are learned pipe in....

Carol

Hi Carol,

I have emailed Mark Randal and await his reply. Meanwhile the next thing is to "fix up" where possible the existing pages. Here are some basic things I see as being needed I am pretty sure these can be done without controversy !

Hoya affinis Needs photos of overall habit, close- ups of leaves and flowers.
Hoya albiflora Needs photos of overall habit, close- ups of leaves and flowers.
Hoya aldrichii Needs a good close up of the flower
Hoya archboldiana x onychoides Needs a couple of good leaf photos - one for overall habit, one close up
Hoya ariadna Needs photos of overall habit, close- ups of leaves and flowers.
Hoya australis All photos on this page need double checking to confirm correct identity
Hoya australis subsp. keysii All photos on this page need double checking to confirm correct identity
Hoya australis subsp. oramicola All photos on this page need double checking to confirm correct identity
Hoya australis subsp. rupicola All photos on this page need double checking to confirm correct identity
Hoya australis subsp. sanae All photos on this page need double checking to confirm correct identity, also, the spelling of the epithet - should it be "sana" or "sanae" - IPNI has sana!
Hoya australis subsp. tenuipes All photos on this page need double checking to confirm correct identity

That should be more than enough to keep everyone out of trouble until I can get some replies in from some of my enquires.

TTFN, KK.

KK...what an energy bunny you are!!! And I think it is great...and personally thank you very much. I will do what I can to fill the voids...

Good, we will get the Photo Files up to date and proper!

Great job!

Carol

KK: I also would like to say Thank You so much for taking on the job of organizing, updating and making necessary corrections to Hoya's in Plant Files! I wish there were something I could do to help but unfortunately I do not have expertise or knowledge about the genus Hoya. I know it must be a time consuming task and your efforts are truly appreciated!

Carol: Many thanks to you also, as well as to Mark, for sharing your knowledge and experience with this great genus Hoya. Hopefully a few others who have a lot of knowledge with Hoya will see this thread and be able to offer some assistance as well.

The outcome of this project will be a great benefit to everyone who searches the Plant Files database! You all deserve Gold Medal's for taking on this daunting project! Thank You, Thank You, Thank You!
