As I said in the email to you on the 3rd, yes, this
is a Homalomena. It is a member of the Chamaecladon Supergroup,
distinguished by small spathes that lack a constriction, but we are unable to
identify it further to species. The plant when you bought it was already mainly
in fruit (inflorescences pendent). The spathe that opened is actually abscising
from the base to reveal fruits. I notice from your images that there are still
inflorescences emerging from the middle of the plant, these have yet to flower,
and you should keep an eye these. Homalomena inflorescences open only
for a short while, usually late in the evening. Initially the spathe gapes
slightly (this is the pistillate phase). Later the spathe will open more widely
(this is the staminate) phase and then close, at which stage it looks as if it
is ready to open. A while later the peduncle will begin to bend to bring the
inflorescences to the position that most are in your images.
The good news is that these plants have certainly not been wild
collected. They are far too clean. My guess is that the originating nursery has
large mother plants and from these removed small offsets and pots separately,
leaves them for a couple of weeks to initiate roots, and then ships.

Subject: [Aroid-l] Fw: Homalomena or ...?
bought an aroid in a pet shop as an aquarium plant.
think it is a species of Homalomena or something from Schismatoglottideae from
leaves are stiff, dry in touch, like the leaves of Aglaonema.
petioles are reddish at the base (but not always).
leaf blades are 12-17 cm long on 11-14 cm long petioles.
produces 2 inflorescences from a node. They are 3 cm tall on 4 cm long
I bought it, 3 days ago, all the spathes were tightly wrapping the
one of them opened, I didn't notice when, but it didn't unroll like most
found it detached from the peduncle, a few cm away.
inflorescence was rotten at the base, so it fell off as I touched it.
female flowers are about 1mm tall x 0.6 mm wide. There are no pistillodes
opened also the second inflorescence,
now I have no possibility to transfer the new photos.
spathe is very thick, the female flowers are green
there is an incredible amount of wet pollen on the male flowers.
may send the photos tomorrow.
seems the plant was brutally cut off by a "collector",
are no roots at all.
hope it will recover in my small greenhouse.
plant looks almost identically as the one that was identified as Homalomena
managed to rescue it, but it is still very small. This one is more robust.
attach 3 photos, these with dates as filenames are Hom. insignis,
beginning from 100 are photos of the new plant)
