Hello Harry,

Similar petiole sheathes you canobserve in juvenile forms of many Philodendron species.

The very first leaves from a newstem often emerge from petiole sheathes,

they unfold fasterthan the typical adult and adolescent leaves emerging fromcataphylls.

For a plant growing in the wildit is important to grow fast in the first stage of its life.

I append photos of my Ph.bipennifolium juvenile cutlings.

Best,

Marek

Dear Harry:

This is Philodendron subgen. Pteromischum. I have forwarded it to MikeGrayum, the expert on this group in hopes he can determine it in this state. It looks a lot like P. auranitiifolium, I think, but there are quite anumber that are similar.

I may be way off Harry but it just looks like ajuvenile Philodendron hederaceum(micans, scandens, oxycardium) based on the stem, venation and onecataphyll. Tom would be the best source. Some have the velvetappearance but many forms don't. We saw a fairly large semi-adult at the Myriad Centeryesterday that had no velutinous appearance and I have several in my atriumthat don't show it as well.

This plant is being passed around the dart frog hobbysince it makes such a nice small aroid to grow in terrariums. It was supposedlycollected in Panamabut I have no other info other than that. If someone had told me it was from Asia I would say it was a species of Pothos. Any ideas onthe id?
