part with congested nodes only about 8 lines apart; stipules 

 adnate to petiole for three lines in length and then prolonged a 

 line more in a triangular point, the whole forming with the base 

 of the petiole a clasping scale 2 to 3 lines wide; petioles stout 

 and fleshy and sulcate when dry, with a knob on the end, flat, i)£ 

 to 2 inches long, about }& longer than the leaflets; leaflets oblong, 

 oblanceolate, obtuse but apiculate, an inch long, often folded, 7 

 to 8; leaves on the season's growth with slender, round petioles, 

 2 to 4 inches long, with narrower subulate stipules, and nar- 

 rowly-oblong-oblanceolate leaflets 2 inches long; leaves silvery 

 with a compact very short and closely appressed, not woolly 

 pubescence, the older leaflets seemingly velvety; peduncle ter- 

 minal, with scattered leaves below and stout, scarcely striate, 

 verticillately flowered from or even below the middle, with the 

 petioles much less pubescent than the leaves, 2 to 3 ft. long in- 

 cluding the rachis of the flowers, slender above, erect; flowers 

 all verticillate and whorls 1 to 2 inches apart to the top; slender 

 pedicels 2 to 3 lines long and ascending and with the calyx as 

 silvery as the leaves; bracts subulate-lanceolate, caducous, 3 

 lines long; calyx lobes about 3 lines long, the upper a little 

 shorter and but slightly notched; flowers about the same as in 

 L. magnificus but 6 lines long and darker, or in some specimens 

 white with a yellow center; pods about 2 inches long, contracted 

 between the seeds, arcuate at base, acute, 2 to 2}^ lines wide, 

 closely appressed-hairy but silvery only when young, seeds at 

 least 6, small; fruiting pedicels are stouter, appressed, and about 

 4 lines long. Forming conspicuous bushes on the gravelly 

 mesas and on the cliffs. Panamint Canyon, Panamint Mts., 

 Cal., on rocks and debris in the canyon, 4000 ft. alt., May 4, 1897, 

 Shepherd's Canyon, Argus Mts., Cal., in clefts of the cliffs 4700 

 ft. alt., April 29, 1897. This is a more glabrous form with smaller 

 flowers. Lone Pine, Inyo Co., Cal., on gravelly mesas 7000 

 ft. alt., May 14, 1897. The latter I take for the type of the 

 species. This is evidently the interior representative of the L. 

 arboreus group.
