Dear Albert,

Now that I am over my virus cleansing, I have had a moment to have a CLOSE
look at your photos, and I do believe that your plant is a Pycnospatha.
The leaves (especially the small one to the left!) and the petioles shown in
the photo #1 are Pycnospatha, certainly NOT Dracontium, as is the spadix
shown in Photo # 2 which lacks the scale-like structures that surround each
individual flower on the spadix as one would see in Dracontium.   It is a
wonderful and rare plant, so enjoy!



.  >>Hello Folks,

  I would like to thank everyone who answered my question concerning the
identification of my plant, formerly labeled D. gigas.

  It would appear that I have been given 3 diagnoses:  D. prancei ( the
favorite ), D. polyphyllum, and Pycnospatha arietina.

  Looking at the pictures that our esteemed friend G. Zhu has on the
webpage, there is certainly a resemblance to D. prancei more than D.
polyphyllum, but I would like to revisit Denis' diagnosis of a possible
with P. arietina.  In particular, the reason for my concern is that the
of the spathe of my plant doesn't quite seem to match either of the
Dracontiums.  The tip of the spathe is definitely curved over until it
almost towards the ground, which is not the case with the suggested

  I have been unable to find a lot of references to Pycnospatha, but looking
the drawings and description in _Genera_of_Araceae_, it looks like it might
a good match.

  Does anyone know of a simple diagnostic difference between Dracontium and
Pycnospatha other than locality?
