The photo looks to be representative of Ipomoea cordatotriloba var.cordatotriloba as per the hair on the capsule and sepals...but (just for referential clarity) if the 'hair' on the capsule and sepals were to be from any type of small licheniform(moldy) growth on the seedpods,then it may represent Ipomoea cordatotrilobavar.torreyana as var. torreyana is completely glabrous...

Nice photo(!)...

Ron, I must assure you there was no mold growing on those seepods.
However they seem to be a little different from the other seedpods shown on the plant files.
I have looked for a picture of var. torreyana to compare the seedpods, but I wasn't able to find one, so I really donn't know.
Do you have a picture of it, or a link to pictures of torreyana?
I have not been able to find any, can you help?
Josephine.

Hi Frostweed,

I just noticed that you added additional pictures and information on here...Thanks(!) for the update...

There are no visibly accurate pictures of Ipomoea cordatotriloba var.torreyana on the web that I've ever seen posted,but I.cordatotriloba var.torreyana is completely glabrous on all parts,so if there is absolutely no visible hair anywhere(esp.on the sepals) then it would be I.codatotriloba var.torreyana...

The ID cannot be based on the shape of the leaves, flower structure or coloration,as any/all variations in these parts can be present in the main type and both varieties...

Ipomoea cordatotriloba and Ipomoea cordatotriloba var.cordatotriloba are both hairy,and although Ipomoea cordatotriloba is hairier than Ipomoea cordatotriloba var.cordatotriloba,there is enough overlap in the official amount and length of the hairs present to make a positive ID 'difficult'...so,if there is any hair at all,it is either Ipomoea cordatotriloba or Ipomoea cordatotriloba var.cordatotriloba...

TTY,...

Ron
