Dear All,

Can anybody tell, what is the best season to start collecting Arisaema C. Martius (Araceae)??
I have some idea about the distribution of this genus in the Western Ghats region..!!!
But many are distributed in North eastern states!!!
It would be very useful, If you could share the locality where you have spotted them...!!

Also, any literature, monographs and reprints about the genus would be much helpfull...!!!

Thank you all

regards

Manudev ji

It is time you should start preparing for studying Arisaemas, the flowering should start by middle of April and may last up to June. Here are Eastern Himalayan species and their main flowering time. expect it to vary 15 days or so on either side: The Western Himalayan plants should flower 15-20 days later.

Arisaema costatum: May-June

A. griffithii: May-June

A. intermedium: May-June, West. Himal: June-July

A. propinquum: May-June

A. erubescence: May-July

A. flavum: May-June

A. jacquemontii: June-August

A. nepenthoides: May-June

A. tortuosum: May-July

A. wallichianum:

Thanks all for the information...!!

I am intending for a collection trip in North eastern states. But I dont have any idea regarding the distribution of these species. I think Simla is a hot spot for Arisaema..

Also I would like to explore Arunachal Pradesh and Assam.....!!

Do we have any members from there..??

Dear Manudev Ji,

Arunachal Pradesh is the best place in NE to study Arisaemas. I would
suggest you to visit Kameng and Tawang districts of Arunachal Pradesh.
Both East and West Kameng districts are full of Arisaemas. Further u
can move to Tawang area where I've observed a few species. If you have
more time in hand....try to visit Siang (either East, West or Upper)
districts also.

You can also contact Dr. Joram Muthu who is working in Dera Natung
Government College of Itanagar as an Asstt. Professor. He has worked
on Araceae of Arunachal Pradesh and has good knowledge on Arisaema and
their localities in Arunachal Pradesh.

Hope this helps.

Regards,
Ritesh.

Dear Ritehshji,

Thank you very much for the information.

Unfortunately, i am not able to make the trip this year as my felllowship has not come yet.

Also, the flowering season is almost complete for Himalayan regions, I guess.

I hope to make it next year.

Anyway I would like to contact Dr. Dera Natung.

Do you have any contact number or email ID?

Anyway thanks again for your help..

A reply:

"Dear Manudevji,
I think June-August is the best time for Amorphophallus sp. in ASSAM. During my field surveys in the western Assam, I have collected A. krausei, A. muelleri, A. napalensis. Attached is A nepalensis.

Regards,
Raju Das"
