Apparently a straggling plant, 1¿- or 2 feet long, glabrous in every part, except the calyx and the ovary,
though the hairs almost disappear on the fully formed legumes.

A straggling plant, slightly hoary with down. Tho leaves and leaflets crowded.
5. P . astragalina. De Cand.—fi. foliolis floribusque minoribus.
We have compared what we have here considered a slight variety of P . astragalina, with the common
alpine and arctic state of the plant, and can find no difference, except in the smaller and slenderer flowers and
leaflets. California, however, must undoubtedly be considered a very southern station for it. It is scarcely
distinguishable from P . debilis, Nutt., but that is a Rocky Mountain and not a coast plant.

N. California, is precisely the same.

H a b . About Snake Fort, Snake Country. {Tolmie.)— Ux Nuttall had considered his A . argophyllus as
probably the same as the A . melanocarpus of Dr Richardson ; but on a comparison of specimens, we find
that not to be the case. The argophyllus is identical with the A . glareosus of Douglas.
3. A. didymocarpus ; suberectus pilosiusculus, foliolis sub-8-jugis oblongo-subobovatis

LX X X I.)
This is a very remarkable species, especially in the structure of its legumes. These are obovate, laterally
compressed, strongly nerved and wrinkled, with the introflexed margins (from beneath) reaching nearly to
the back, so as to divide them into two compressed one-seeded lobes.
