Thank you for the response! And thanks for the included document, very good to read! This also confirms some feelings I had. Albizia kalkora (Roxb. Prain)
is indeed what I am talking about. It is very hard to find out about things, especially in English as the species is so unknown here.
What we see and determine as Albizia kalkora (Roxb. Prain)
is pretty basic and based on Korean research. 4(to 6 but we classifie it as doubtful hybrid than) pinnae and max. 12
(to 14 but we classifie it as doubtful hybrid than)
leaflets per pinnae. Distinctly different as the note suggests, I see. Also, one distinct feature that looks dominant in hybrids is the smooth bark of A. julibrissin
I have seen the similarities between
Albizia kalkora (Roxb. Prain)
and Albizia odoratissima
but when I google the name two distinct species show up, maybe synonyms? (one has the more round puffy orangy-white flowers). Either way the flowers look more like big tall clusters in odoratissima
, is that correct?
We see the Albizia 'coreana'
collected from Yudal mountain by the JC Raulston arboretum in America as a example of a pure Albizia kalkora
. This Arboretum supports me in this search and we are trying to get some (pure) seeds from that specific mountain back again as we think this is the most cold locality with temperatures below -17 degrees celsius from hearsay.
Our concern about the species is the genetic dilution, hybrids are showing up everywhere. In November I should get some seeds from Japan, Miyazaki prefecture which hopefully are pure, these should be weaker in cold than the locality from Yudal mountain.
A hybrid I own with julibrissin
and the tree in America(A. kalkora
In Japan I believe some hybrids are even naturalized they call this group Albizia julibrissin f. Glabrior.
I am trying to figure out which region of China the A. kalkora (Robx. prain)
are collected. But the plants look something like this:
A little more pointer than the tree in America looks like. But in my experience with A. julibrissin,
individuals can develop very distinctive traits. I believe this is the same in the whole genus, what makes research even harder I suppose.
We are trying to figure out a lot but it is hard for us, pardon me if there are some incorrect statements. I am trying to set up a breeding group with individuals with A. kalkora
here in Holland because there hardly any risk of invasiveness due to our climate. Also, we can control pollinationa more. In America A. julibrissin
is very invasive and is hard to control, our season is too short for seedlings to germinate and harden off before winter.
Do you perhaps have any insight in A. sherriffi
? Would it be possible to have seeds collected someway? I would love to share some with the JC Raulston to investigate and learn from but also to set-up a secure breeding group here in The Netherlands. This is insurance group could be propagated and is also good for our understanding of the species. In Europe this is very unknown and in America people have a distaste for the genus because A. julibrissin
is seen as a obnoxious weed, so there is not a lot of research there either.
Would like to know what you think of my A. kalkora
'assumptions' I suppose. And your stance on A. Sherriffii.
Thank you for your knowledge and time. Hopefully it is a interesting subject for you aswell.
It is greatly appreciated! Sincerely
