Salix hastata L.
Annotated by G.W. Argus, 2008.

Yukon Territory: Snake River Drainage, Popcornfish Lake. Elev. 2743'
65.45737°, -133.79553°
40° NNW-facing slope in mossy Dryas heath tundra with lots of moss and little lichen with Dryas alaskensis, Salix reticulata, Cassiope tetragona, Arctostaphylos alpina, Oxytropis borealis, Tofieldia pusilla, Rhododendron lapponicum, Oxytropis maydelliana, and Minuartia arctica. Leaves glaucous, fish-hook hairs, old branches with flakey epidermis. Revised with the notes by Arugs. Although this is a very great range extension, I believe that it is closest to farriae. I have compared it with both barclayi and hastata. It fits farriae in all characters. It differes from barclayi in slender stigmas, short styles, red-mottled ovaries and glabrous floral bracts and from hastata in glabrous juvenile leaves and geniculate branchlet hairs (G.W. Argus 2005). There are no juvenile leaves present but the glabrous young leaves, despite the lack of ferruginous hairs on the adaxial midrib, suggest S. farriae. It is a significant northward range extension, almost reaching the known range of S. hastata in Yukon, and could be an intergrade with S.hastata (G.W. Argus 2007). Leaves lack ferruginous hairs, styles 0.22-0.25 mm, stipes 0.9 mm, nectaries 0.42 mm, female flowering branchlets 2-2.3 mm. Best determined as S. hastata. DAO Acc#825059 barcode 01-01000588450. Uncommon. Previously identified as Salix barclayi. Previously identified by B.A. Bennett, July 2005. DAO; CAN
