Albizia sherriffii (Leguminosae: Mimosoideae) : 3 posts by 3 authors. Attachments (2)
Botanical name: Albizia sherriffii Baker.f. (Leguminosae: Mimosoideae).
Location: Nagaland, India
Habit: Trees, 10 – 20 m high.
Habitat: In primary forests between 800 – 1200 m altitudes, ascending to 2000 m on the Himalayas (in subtropical forests).
Distribution: India (Sikkim, North-East India), Bhutan, Myanmar and China.
Tree species Albizia:
Firstly, sorry to message out of the blue and I’m sorry to bother you also. I got your email address via EfloraofIndia. Hopefully, you are doing well.
I am busy with research regarding Albizia species. I am collecting Albizia kalkora seeds from different localities for conservation matters. In short, this species is being overwhelmed by the more vigorous A. julibrissin and outcrossing with kalkora, the hybrids are fertile and outcross also. (The invasiveness of julibrissin is rampant in the USA). Especially isolated places like Japan and Korea are at risk of eventually losing this species due to genetic dilution.
I am setting up an insurance colony for these localities, I got some from mainland China, Hopefully in November from Japan. I am also busy with Korea but that one is especially hard but the most isolated and endangered.
I am planning to DNA test for any genetic differences in the Bio-Informatica lab at Groningen, The Netherlands, I live here also. Besides that, I want to test the relationship between A. kalkora (and hybrids, we have 3 hybrids of julibrissinXkalkora), julibrissin, A. lebbeck (and hopefully A. sherriffii as well with some help).
Now I stumbled across Albizia sherriffii Baker f. (syn. Albizia vernayana Merr.). From the research I did, it looks like its spread(Sikkim, India-Tibet-Bhutan?) is pretty isolated because of the mountain ranges. I suggest this species could encounter the same problems as A. kalkora, with A. kalkora and A. julibrissin being just as hardy it could infiltrate A. sherriffii its habitat and most likely outcross also. A. julibrissin is planted a lot for its tea properties and esthetics. It would be safe from the vigorous A. lebbeck because lebbeck is not tolerant of cold.
There is a lot unknown about both species A. kalkora and A. sherriffii and I would love to put sherriffii in the same test as well, to see how they all fit together, it is a pretty interesting species because it has some similarities with julibrissin as well. Also, because I am setting up an insurance colony for A. kalkora localities I would also like to do this for A. sherriffii as well.
Hopefully, you could offer me a helping hand. Any help is appreciated. Maybe you know something of the tree yourself, or have close contact with it, or have some contact of a botanical institute for me? (maybe an Index Seminum?) Hopefully, with your network you could help me further, it would be greatly appreciated!
I would like to point out that the type of the name Mimosa kalkora Roxb., the basionym of Albizia kalkora (Roxb.) Prain is not traceable. Therefore, unless the name is neotypified, and the characters elucidated, it continues to represent a plant of dubious identity. In this context, please also look at the attached short Note.
In view of this, I would suggest getting the samples of the supposed “Albizia kalkora” identified through an expert before going ahead with further studies.

Thank you for the response! And thanks for the included document, very good to read! This also confirms some feelings I had.
