  Fabaceae Lupinus argenteus argenteus
Scanned 26 Oct 2011.

This was an attempt to visualize the stem hairs. The question is: are they appressed? The scan makes it look like the stem hairs are spreading, but under the microscope, about 2/3 of the hairs are appressed, and 1/3 spreading.

Characters observed while keying: Perennial > 1 dm, stem hairs appressed, leaves cauline, petioles 4-4.5mm, calyx spurred <= 1 mm, banner back hairy, keel upper margin ciliate distal half.
