ID help

A question was posted at another site and I said I would try to get some answers. They want to know what these 2 wild morning glories are and if they would cross pollinate with heavenly
blue?

nice MGs but i have no idea Paul

I'm thinking that the second one with the blue flower is Ipomoea hederacea with the cordate leaf. The half hidden flower in the foliage picture looks like it has the characteristic hairy curved sepals.

The first one has a flower that looks a lot like Ipomoea pandurata, but I can't say I can readily see the wide, ridged sepals that I. pandurata has....and I do not know if I. pandurata can or cannot climb shrubs like is pictured and if it can have the heart-shaped leaves...

Of course, the definitive opinion will be forthcoming I'm sure...!! I've learned a lot from Ron and just wanted to commit my guess before the correct answer is revealed...

The first photo here
http://img59.imageshack.us/img59/1175/35885908eo6.jpg
shows an Ipomoea pandurata flower in the upper left and the sideview showing the sepals is somewhat atypical for Ipomoea pandurata as the ridges on the sepals are not very apparent...nonetheless I do see some ridges and even a large black ant feeding at one of the extra-floral nectaries(EFN's) at the base of the outer flower in the center of the photo and a large black ant in the cluster to the left...large pugnacious ants are known to populate Ipomoea species with EFN's...

The frontal flower photo and the sideview are Ipomoea pandurata...

The leaf in the right does not belong to Ipomoea pandurata,but belongs to a different family of vines that is growing intertwangled in with the Ipomoea pandurata...

The photo here
http://img59.imageshack.us/img59/5495/81209857nm0.jpg
shows on the left a typical Ipomoea hederacea flower and the view of the leaf with the hairs protruding at an angle consistent with Ipomoea hederacea...

The photo on the right shows a different bloom with sepals that may not be Ipomoea hederacea due to the absence of any visible substantial outward curving of the sepals nor are the tops of the sepals curved downward...the sepals on this sideview of the flower look most like Ipomoea nil...but,the sepals of Ipomoea hederacea may not always show the distinguishing curving or curling until after the seedpod begins to mature as seen here

The following link shows Ipomoea hederacea misentered as Ipomoea hirsuta...there is currently no legitimate Ipomoea species epithet of hirsuta accepted by the International Plant Names Nomenclature Index...I've reported this several times,but as of yet >to no avail...This 'old entry' which has no legitimate current objective scientific basis still 'lingers'...

The sideview of the flower here
http://img59.imageshack.us/img59/5495/81209857nm0.jpg
shows very visible purple-fuchia on the outside near the top of the tube...the same amount of coloring is usually more prominent on the inside of a tube if coloring is present on the outside of a tube...
Ipomoea hederacea most usually has an all white tube...
The flower in the sideview seems very unlikely to be from the same plant that the frontal view shows...

The flower in the sideview may be an unusually colored Ipomoea hederacea with sepals that look like Ipomoea nil and with cordate leaves...or it may represent an Ipomoea nil flower growing in a patch of cordate leaved plants...

The plant here e.g.,
http://davesgarden.com/pf/showimage/139620/
might at first appear to have serrated lanceolate leaves unless you look alittle further to see the more typical Ipomoea hederacea leaves...

Ipomoea tricolor will not naturally (or by hand pollination) cross fertilize with Ipomoea hederacea,Ipomoea nil,Ipomoea pandurata nor with any plant with leaves resembling something in the Vitis genus...most likely Vitis rotundifolia...

Ipomoea tricolor has not been known to cross fertilize with anything but other Ipomoea tricolor...

Hope that helps...

TTY,...

Ron
