Here is an interesting entry in an old botanical text from the 1800's. Interesting that is calls purpurea a "bindweed". By the time I hit college they were no longer offering latin, now I wish I had had the opportunity to study it. I scanned the text seperately so it can be seen better in the next post. Even the font characters are strange!
The text
Are they saying its a white flower with five spots?
Yes, the text goes with the photo.
Information
This beautiful, original hand-colored engraving by William Curtis is from his work entitled Botanical Magazine. Curtis lived in London and worked as a pharmacist but his interest in the natural world, particularly plants and insects, soon overtook his life. In 1787 his Botanical Magazine was first published. He continued with the work until his death in 1799, producing volumes 1-14. John Sims took over the publication after Curtis's death from 1801-1807 and produced volumes 15-26. The well-known Sydenham Edwards was the principle artist on the work for both publishers (Edwards later produced The Botanical Register 1815-1847). It is becoming harder and harder to find the top images from this series, thus the value of each of these prints is increasing from year to year rapidly. Curtis botanicals make for marvelous, decorative pieces when framed and hung on a wall.
I believe the engraving is dated 1807.

So the spotted form now usually called "Milky Way' was hanging around in 1807...

The gene that causes the partial midpetaline pigmentation is called the "spotted" gene...when I see these flowers I usually think to myself "okay,it's carrying the spotted gene"...like the vast majority of Ipomoea purpurea...although most 'purps' also have colored limbs and sometimes 'purps' without the gene for any spotting are seen
Ipomoea purpurea without any visible darker spotting here

Ipomoea purpurea dilute causing the spotting pigmentation to appear only on the upper portion of the primary fold...

The flaked gene modulating the appearence of the spotting

The yojiro hybrid suppressing the gene for spotting

I like the description that mentions analogous designs around the 'eyes' of feathers...interesting..

Where did you find the website with these pictures?

Look up at the tabs in the top and you will see plant files. Plant files is a searchable data base here on Daves Garden.
I`m not trying to hi jack the whole thread but...
Ron,did you mean the yogiro pattern doesn`t show white spotting? I had some yogiro flowers that showed full color with white rays and leaves that were not variegated but they were splashed looking,divided color light green and dark green. I saved all the seeds from that to see if the trait would come back and maybe the flowers had hidden trait for spotting? Then I saw some on ebay showing leaves and flower with the divided colors. The flower had the white spotting and it looked very interesting.
gardener2005 - The spotted gene produces a darker pigmentation along the primary ribs...it only affects the corolla...not the leavers...the genes affecting the leaves are usually different than those affecting flower color...
White is the absence of the darker pigmentation...
The white rays along the primary folds in the yojiro hybrid flowers do not show the darker pigmentation the way it is expressed on the non-yojiro Ipomoea purpurea...the gene for spotting is either absent or suppressed...when color pigments do appear along the primary folds on the yojiro hybrids >it is most often the same depth of color as the main limb or lighter ...not darker...

P.S. - I think Kay may have been asking Beth where she found the website to the old stuff from the 1800's...
Thanks Ron. It is good to know the genes for leaves and flower color are different. I only wondered if maybe there was something hiding in the flower color..because of the solids that appear from seeds off yogiros(straight from Japan too) on occasion. I`m learning here.
Forgive me for answering hastily to kay`s question.
If Kay was asking me where the old botanical scans came from, it is not a website. It is from the original botanical magazine that I own, and I scanned it myself.
Beth
Do you think that the Gypsy Bride came from that to?
That is what I thought. You did write that you scanned the text. It is very cool btw. I`m thinking of doing some artwork of my own with some of my pictures I took this past year.

phicks - good observation...sure does look like like the milky way picked up on a gene that causes the hige type of doubling and splintering...
Kay, here's a website with 1,048 plates of William Curtis' botanical artwork. The images are open-domain, though it's hoped their use will be attributed to the National Agricultural Library in Beltsville, Maryland. If I ever unsnarl our printer, I'd love to print out some of these on home-made seed packets for trade.

To find it, I keyed Curtis + magazine into www.google.com search box.
Baolvera, thanks for sharing some of that magazine with us - love those old plates, too.
OK you guys got me to get my latin dictionery out, and iron my rusty 2 years of latin in high school.
The description mentions eye spots, heart shaped leaves, the ovary has 2 halves, the vine is quite tall, and the seed pods face the ground. You all knew this already. I am amazed nobody stated a thread about the use SSSSS that looks lik fffffff. Please notice that when used as an S, the cross on the f is completely and only on the left side, and doesn't cross through the shaft.
I tripped on this and fell on my face one time while researching earlly AmericanHistory, where I came upon a mortality report after an Indian attack in the 1600s. The report gave the name of a woman and her sucking child, with the other kind of s. I had to think long and hard to iron this out,
, but my analys of the use of this archaic character seems to re right on the money. Frank
