Of course Alexei was fascinated with the unusual plants of Hawai'i's Rainforests. He took several photos of this Mamaki bush Pipturus albidus, in full bloom! It is a member of the Nettles Family, Urticaceae.
Alexei left, well pleased with the research he did while here. He said that he had enough research material to help write several papers on rare tropical Arailiads, and other members of the Apiales Order.
Alexei has a lot of material available for viewing and study. He is involved with a large amount of plant research.
Google: Dr. Alexei Oskolski, and Komarov Botanical Institute to find out more.
Here is another view of Clermontia lindseyana with an open flower!
Must have been an interesting excursion. Oddly enough there is a tetraplasandra growing in the gardens of the Santa Barbara County Courthouse in Santa Barbara, California. Until I saw that specimen I thought they could not survive out of doors in California.
Those Russians get around. Some of the early work done on New Guinea flora was by a Russian botanist. Had to check what exactly Araliaceae were. We only have 3 here in the Territory, although of them the Umbrella Tree (Schefflera actinophylla) would be the most widespread these days.
I can't imagine your Russian coming up with "Cyanea", though. It would have been in Cyrillic script. ;O)
