[Mike Slater]

Hi Erick,

It might be the smaller subspecies A.triphyllum ssp. pusillum. The spathe 
flange (the rolled edge at the opening of the spathe tube appears to be very 
narrow (< 4mm I believe is the description usually cited) and the flower 
size and overall shape is right. The Green color ( with no dark reddish 
black ) is found in ssp. pusillum around here occasionally. The spadix does 
appear to be slightly clubbed at the apex which is more of a ssp. triphyllum 
character.  A.t. ssp. pusillum is similar to ssp. stewardsonii in several 
respects. Both: have the underside of the leaves glossy green not whitened, 
prefer swampy wet areas, are diploid (as opposed to the tetraploid A.t. ssp. 
triphyllum and both normally begin to bloom as the larger A.t. ssp. 
triphyllum is finishing.

Several years ago I found some A.t. ssp. pusillum in a State Park near our 
house in bloom in October and there was a plant with ripe seed also. I have 
never come across a late bloomer of ssp triphyllum.
