International Aroid Society

Dear Marek: Do know the source of origin of your collection? I am just trying to figure out how reliable the determination is.

Hello Harry,

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

The very first leaves from a new stem often emerge from petiole sheathes,

they unfold faster than the typical adult and adolescent leaves emerging from cataphylls.

For a plant growing in the wild it 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 Mike Grayum, 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 a number that are similar.

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

This plant is being passed around the dart frog hobby since it makes such a nice small aroid to grow in terrariums. It was supposedly collected in Panama but 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 on the id?
