Dear Eduardo & Tom,
If the image in the pot is THE plant then it is very
convincingly Aglaonema. Note the weak pulvinus. All Aglaonema have a pulvunis
in that position. Asian Homalomena are all pulvinate, but the pulvinus is virtually
always ca 1/2– 1/3 up the petiole (from the base – exceptions include H.
crassinervia and a handful of new species, but this plant is none of them.
Eduardo: Very good to hear that you are also generating a slew
of new genera – makes us here in Asia feel less lonely/outlandish!

My Internet Explorer is not working right now. We just got the review
copies of this paper describing this “new” species and I think I will ask
Norbert Killian to postpone publishing this until I can research this further.
I will try to send images to Pete and will study the image you linked
below as soon as my system works. Meanwhile I am hoping that our plants
flower again so that I can get more details. Eduardo, since you probably
know this thing best by now and have described this related genus I will send
you the pickled inflorescence. Would it get to you if I mailed it?

hypothesis of an escaped Aglaonema (quite common in some places in Amazonia) is
just a clue to check on it, not a final word. Indians use to keep
beautiful plants with them as charms (“beenas”, as Julius would love to
mention) and many cultivated exotic species can be found in abandoned
settlements (including sansevieras and variegated Colocasia). Anyhow,
discarding this hypothesis and considering many aspects, it could even be
something else. In my opinion (only based on a limited set of pictures,
together with a description) it doesn´t seem to be closer to Bognera than to
any other “philodendroid” genus. However, considering that Bognera is
monospecific, we simply know nothing about acceptable intraspecific variation.
The “third” species of Bognera from Northern Brazil has just proven to be a
brand new genus! (confirmed by molecular phylogeny)
Tomorrow I will check if our A. costatum is flowering and, if
so, I will send you a picture. But there is a nice close up of the
inflorescence of this species in http://commons.wikimedia.org/wiki/File:Aglaonema_costatum_003.JPG
. It is impossible to see female flowers, but you can compare with your picture
(they are both at the male phase). It would also be useful to send your picture
to Peter. He knows Asian genera pretty well and his opinion would be really

This IS a new Bognera.
Josef knows all about this.
He mentioned it to me
on the phone only last week.

Subject: Urgent Request to
List members, a strange new collection
I have described a plant collected in a remote habitat near the Brazilian
border in Peru. It was collected by a friend in California who has been
growing it as an acuatic. It has a definitely creeping stem, rather short
petioles and in many respects looks like Aglaonema costatum.
It keyed out to Bognera and
I assumed that it was a member of that genus but Eduardo Gonçalves has some
doubts and is wondering if it could have been an escaped horticultural
collection. Although that seems somewhat unlikely I would like to see any
images that any of you might have of Aglaonema costatum in order to make a better
judement. It would be especially useful to see a close up of the spadix
if any of you have that species in flower at this time.
Thanks in advance for any help that anyone can render.
