  Possible Typhonium identifications?
From: Ken Mosher ken at spatulacity.com> on 2005.12.14 at 05:13:33(13594)
I know identifying plants by their leaves is fraught with danger, but
I've also noticed that Typhoniums seem to have fairly different leaves
from each other. I have 5 photos of unknown Typhoniums from this summer.
If anyone would like to volunteer as guess as to what they are that
would be great. I'm sorry but none of them produced an inflorescence.

Unknown Typhonium #1

Unknown Typhonium #2 (sorry it's so fuzzy)

Unknown Typhonium #3

Unknown Typhonium #4

Unknown Typhonium #5

Hi Ken,

I am afraid you will find that you've over-estimated the art of recognizing
Typhoniums in leaf. In my opinion none of your plants shows a leaf-type
unique for only one species. To boot, most are rather early in leaf
development or young plants and many Typhoniums change leaf shape
dramatically when getting older or when producing leaves later in a season.

Sorry I can't help you but I am not the only aroidologist, so maybe somebody
else will surprise us.

I would have to echo Wilbert's statements about recognizing Typhonium
species by leaf.
I looked at your pics and for each one of them, there could be at least 3
possible species.
So for accurate identifications, you'll have to wait for them to flower.
When they do bloom you'll only have a few hours to get good photos, as the
spathe color
fades very quickly once they bloom.

Thank you, Lord P. Yes, they were young plants, although the photos were
taken late in the season. I'll grow them another year and I expect
they'll flower then. The tubers I planted were tiny and the ones I
harvested were nicely sized.
