Griffith’s Cobra Lily;
 
Arisaema griffithii is a variable species and particularly in the Yumthang valley many brown forms grow side by side with the more typical griffithii. Travelling further up the valley beyond the hot spring towards Yumesodong & zero point the plants get smaller, the spathes get more narrow and the appendices thicker and more contracted until they morph into forms close to Arisaema elephas. 
 
The purple-brown forms of griffithii are sometimes identified as Arisaema utile (of cultivation) but that is incorrect, in my view that name is a full synonym of griffithii. The holotype of utile was collected from near Lachen and is a different form of griffithii with a longer peduncle. 
 
This is a narrow spathed variant of the griffithii alliance. With some variants it is difficult to assess whether they are still forms of griffithii with a narrow spathe or big forms of propinquum with a wider spathe as they seem part of a continuous variational range going from one extreme (griffithii) to the other (propinquum). I have studied this group in the Yumthang Valley and the variation is endless, particularly at the higher elevations and forms like this ultimately morph into elephas type plants. Due to this it is impossible to attach a definitive name to many plants from this valley other than that they belong to the “griffithii” group. 
 
The same variational patterns for griffithii and allies occurs in the Shingallila National Park and several places in Nepal.  


 

Identification of Arisaema – regarding. (mixed thread) : 2 correct Attachments. 3 posts by 3 authors.

Let me introduce myself. I am a nature photographer from West Bengal ( India). During my visit to Sikkim and Singalila Forest (mainly through Darjeeling District of West Bengal) I had photographed some different Cobra Lilies (Arisaema) which I failed to identify.
Now, I am sending the photographs for your valuable comments.
………………………
Photographs : 3A & 3B : Photographed in Singalila Forest (near Gairibas). Could not found in full blooming condition. Altitude : 9,000 ft. Blooming Time – April. Are they Arisaema griffithii ? Kindly confirm.
……………………….

……………….. 1 to 3 appears to be what you have stated as per this book.
Others may like to give their views.


I recentlty joined and saw this old thread. I can give some ID’s which could help for future reference if you still need them:
……………………….
3 A & B = Arisaema griffithii, this is the lowland form originally described as Arisaema hookeri/hookerianum ……………………

That is indeed the correct ID.

Travelling further up the valley beyond the hot spring towards Yumesodong & zero point the plants get smaller, the spathes get more narrow and the appendices thicker and more contracted until they morph into forms close to Arisaema elephas.
