There didn't seem to be any photo of Carrierea calycina on the forums, though there is a thread of that name in the Davidsonia forum, with a link to Peter Wharton's Davidsonia article entitled "Carrierea calycina, the goat horn tree – a two part account of its history in western cultivation and recent reintroduction". The Carrierea in the garden were grown from seeds collected by Peter Wharton. The last photo in this group was from May 9 this year, same accession but different individual. I think it was Douglas Justice who wrote the description, in a photo specification document, of "leaves with distinctively salicoid marginal teeth, with each tooth terminated by a small spherical gland". Too bad I forgot to check that while I was there, but maybe these photos show that. This tree is in the Salicaceae family now. Nadia is really put out that we have not seen flowers on these trees, yet she has seen the flowers at VanDusen.
I didn't remember why we were interested in Carrierea nine years ago, but I remembered that it was the case, so I photographed this one that I came across today, to the west of the Wharton Grove and this whatever-it-is area.
