Dear Aroiders...
While in Puerto Vallarta, I came across a large potted aroid (in
fruit/flower) at the Paradisus Hotel. I haven't gotten my pictures back
yet, but in the meantime, the plant was perhaps somewhat less than 3 ft
high and 3 ft wide. The leaves were many, about 2 ft long, 6 inches wide
and very short petioled, giving the plant the appearance of a large birds
nest fern, but with heavier and darker green leaves. Any suggestions for
me to cogitate upon until my pictures come back?

Dear Don,
Try one of the "birds nest Anthuriums.
Sincerely,
Julius

Don: My guess is that it is Anthurium schlechtendalii var. jimenezii
but I would be glad to look at your photos to be sure. Certainly it
must be a member of sect. Pachyneurium and there are only 2-3 in that
region.

On a trip this past week-end to the Olbrich Botanical Gardens in
Madison, WI, I saw the plant pictured in the following link: (the one
I'm holding in my hand)

http://home.wi.rr.com/llmen/unknown.jpg

It looks to be a climbing aroid of some sort, maybe Philodendron?

Any suggestions?

Don,
I believe that this is an Anthurium species, but I'm not sure of
the species, and don't have any of the books I need here at the home office
- they're all at work. I would look in the Anthurium of Panama Mobot
Monograph Tom Croat put out a while ago now as my first choice. It looks
familiar to me, and we worked alot with Panamanian collections for awhile
at one of my former haunts.

Hello all,

[just thought I should finally contribute something after being on
Aroid-L for ages!]

The plant in Don's hand looks a lot like an Anthurium I used to grow -
A. polyschistum. As a young plant it has a thin, flexible vining stem
with long internodes, almost like some Syngoniums or Monsteras in
texture, and quite unlike other Anthuriums I've seen in cultivation. The
leaves are also quite soft and thin (and beloved of two-spotted
mites...). Not being an Anthurium expert I'm not certain about my
suggested ID, but I hope it's on the right track.

There are couple of pix of a nice plant of A. polyschistum in flower, on
David Scherberich's web site:

http://dscherberich.free.fr/MONTET/anthpolyschistumncy.html.

Looking at Tom Croat & Richard Sheffer's 'The Sectional Groupings of
Anthurium (Araceae)' on the IAS website
(http://www.aroid.org/genera/Anthurium/anthsections.html), A.
polyschistum is classified in section Dactylophyllium, which contains
other species with palmately compound leaves such as A. pentaphyllum and
A. clavigerum.

Incidentally, out of curiosity I also looked up A. polyschistum in
Missouri Bot. Garden's W3Tropicos database
(http://mobot.mobot.org/W3T/Search/vast.html) - a good online resource
with records for many herbarium specimens of aroids from tropical
America, and also quite a few photos of the plants in habitat. A number
of collections of A. polyschistum are listed from Napo in Ecuador; it's
also known from Amazonian Colombia, Loreto in Peru and Acre in N.W.
Brazil.

Hope this is useful.

cheers
Eugene

Looks more like an Anthurium to me, but can't
tell which one.

Thanks to everyone who helped ID my unknown photo as Anthurium polyschistum.

Don, Anthurium aemulum is another 'fingered'
leaved type that is worth growing if you don't have it. About as common as
polyschistum. I like these
viners better than many of the 'birdnest' types.

Attached is the photo of an Anthurium I took in Chachagua, Costa Rica. Although the photo doesn’t show it well, the inflorescence seemed to

have a definite pinkish case. It looks like it might be one of the Pachyneuriums, but that’s beyond my expertise. Any suggestions?

Dear Don: I recognize the species but do
not recognize its name. Do you have and image of the cataphyll and petiole
cross-sectional shape, both good for trying to key out the plant. I assume
that it is native to Costa Rica. Unfortunately the spadix color is
post-anthesis so it won’t be of much help but the infructescence is fairly
unique.

Dear Don:

Where is Chacagua in Costa Rica. I
still hope to determine this Anthurium sect. Pachyneurium for you.
