heh...looks like brian and others have seen the same weird plants that i have...possible hybrids....

One additional point....when i say "pruned", i actually removed ONE lower leaf, that's it....this plant generally has very few leaves, widely dispersed and spread out....the pumpkins in the background seem to fit the pic since the plant is sorta grotesque and "spindly", perfect for halloween....i was thinking that it's a weird P. bipinnatifidum, but the stems like i said do not seem to indicate it is that species (although i'm hardly an expert)....

Hi guys:

More pics from me and a pic from Leland Miyano....

Here is the overall look of the meconostigma aroid....i just pruned it so there are less leaves, but it generally is slow growing and has less leaves than my other aroids...In this this pic, note how ALL the leaves are distorted and curved on themselves:


Here is a close-up of the stem...it does not look like P. bipinnatifidum, with its rather persistent spines..


Here's P. bipinnatifidum for a comparison:

Leland was kind enough to send a pic for people to compare with the previous pics I sent...here:

Yep, it has grown up quite a bit and it looks nothing like any aroid i've ever seen...the distance to the ribs is equal from tip to base all along the leaf, and the leaves are leathery and have a very pronounced tendency to CURL into itself. weird....looks cool though with the shiny leathery leaves...

Two pics of a young leaf...below it you can see darker colored, CURLED, leathery, older leaves.

Dear Arlan,

Aloha. That is definitely not Philodendron
adamantinum...compare that leaf with the scans I sent
you and also key it out using Julius Boos'
