Fig. 8.
Appressed satiny pubescent throughout, prostrate, much branching from a perennial crown.
Leaves short, very densely set or crowded along the lower stem, leaflets three, very small, rounded, and scarcely mucronate; the upper leaves larger, leaflets four (only one of the lower pair developed), obovate obtuse, very abruptly mucronate-acute; stipules red, minute and gland-like, glabrous. Peduncles twice the length of the leaves; umbels six to ten-flowered, bract of a single sessile obovate leaf (a few separate pink glands or embryoid stipules often present).
Flowers orange yellow throughout; keel obtuse, wings and banner equal; teeth of the calyx about one-third its length, acuminate, embryo legume terete, appressed pubescent, two-seeded; mature fruit unknown.
From Kern River, pendent from rocky cliffs. The Society is indebted to Mrs. Hutchings for this new and very beautiful species.
Dr. Ayres presented a paper by Dr. T. M. Logan, of Sacramento, on the Physics, Hygiene, and Thermology of the Sacramento River, which was read and referred to the Publishing Committee.
