Betr: new site/Pinellia question

[pbruggeman at TISCALI.NL]

David,

Are you sure? Is it similar to the plant on the picture of that website and
is your plant truly an Arisaema? Quite long threadlike, hanging appendix?
-From what I understand from your remarks underneath it seems you are more
likely dealing with a rampant Pinellia than an Arisaema.

The structure of the flowers of Pinellia (which CAN become a weed, I wish
Arisaema were like that :-}.......) is different to Arisaema. Pinellia are
always bisexual with the female part of the flower fused with the back of
the spathe. The seeds are never red but always green and covered in a papery
white "skin". The seeds usually drop from the seedhead and what is left makes
clear part of the spadix of Pinellia is fused with the spathe.

The only Pinellia species with tripartite leaves are P. ternata and P. tripartita
(and P. yaoluopingensis but the status of that one is questionable) and both
look like nothing like the plant on the picture Bonaventure was referring
to.

Are you sure it is not Pinellia pedatisecta with pedate (5-7-9 foliolate)
leaves?

Pascal

(read, yanked) out 2 dozen plants and noticed a seed pod spill it contents.
Cursed for a few minutes and continued yanking out more plants.  They pop
up
everywhere.  I'm glad to
