Larix griffithiana Accession 29849-523-91 (1/4) May 13, 2011 Photo: Wendy Cutler This is not the same accession as was posted originally, and I'm just assuming that griffithii and griffithiana are meant to be the same thing, which is why I'm posting this here. The needles were a lot more developed in the 2002 photo taken at almost the same date. 2011 has been a late year for everything.
Yes, correct; Larix griffithii is the valid name, and L. griffithiana a synonym. Possible though that some of the above plants may actually be the recently described Larix kongboensis, rather than L. griffithii.
Here's the original photo. I had tried to crop out confusing bits from other trees, but maybe seeing the slightly longer branches is helpful. Those are the seed cones on the branch in the centre? One of the branches has just cones, but the other has leaves and cones.
That's an old style label that was photographed (how old? probably since the tree was accessioned ~ 1991, but certainly before 2000 as we stopped making that label style then) -- hence the non-updated name.
Just noticed the KR1676 on the label, that's definitely L. griffithii, Keith Rushforth's collection from Sengor Chu, Bhutan, at 3000m altitude. Cones up to 7.6 cm long. L. kongboensis comes from the drier Tsangpo Valley north of the front range of the Himalaya. Daniel - do you have collection details for the other two accessions shown higher on this page?
Both of these accessions of L. griffithii, were collected near Sengor, Bhutan by Keith Rushforth. All plants of accession 29813 KR.1769, show as dead or removed from the garden. Two trees of accession 29849 KR.1676 are still listed in the database.
