Astragalus oxtphysus, Gray. This species is described as hav- 

 ing inflated pods. Fruiting specimens have recently been collected by 

 Mr. Lemrnon in the northern part of San Luis Obispo County, in which 

 the pods are much compressed and distended only partially in the 

 middle, both sutures being acute and the ventral one straight. The 

 stipe is villous and as much exserted from the narrow calyx-tube as in 

 A. leucopsis, which the species much resembles in appearance. 



Lathtrus cinctus. Sparingly pubescent throughout: stem stout, 

 angled : stipules foliaceous, semihastate, lanceolate, nearly an inch lon^, 

 the broad basal lobe coarsely toothed; leaflets 10 to 15 pairs, nar- 

 rowly oblong, obtuse, mucronate, 1 to U inches long: peduncles much 

 shorter than the leaves, few-flowered : calyx short, the longer teeth 

 equalling the tube ; petals 6 lines long or more : pod nearly straight, 

 broad, H inches long by 5 or 6 inches wide, 3-5-seeded: seeds orbicu- 

 lar, nearly surrounded by the hilum, 2^ lines broad. — Near Tolon, 

 Monterey County, California (T. S. Brandegee, 1886). A very dis- 

 tinctly marked species ; turning black in drying. 



Lathtrus palustris, Linn., var. (?) graminifolius. Leaves 

 very narrow and elongated, 2 to 4 inches long and often only a line 

 wide or less ; flowers variable in size and color, often yellow. — Fre- 

 quent from New Mexico to Arizona and northern Mexico. 



Ivesia Shockleti. Alpine, dwarf and cespitose, the stout much- 

 branched caudex compacted with the persistent remains of dead leaves, 

 finely pubescent throughout and more or less glandular : leaves 1 to 1 \ 

 inches long or less, the petiole usually ciliate and somewhat villous at 

 base ; leaflets 3-parted, approximate or imbricated, rarely a line long, 

 often setosely tipped : inflorescence open, few-flowered : calyx small, 

 campanulate, becoming rotate, the deltoid lobes exceeding the white 

 spatulate petals: stamens 5 or sometimes 10: pistils few (6 or less) 

 upon a villous receptacle. — Summit of Silver Peak, Alpine County, 

 California (/. G. Lemrnon, 1873) ; in the White Mountains, Mono 

 County, at 13,000 feet altitude (W. H. Shockley, 1886). 



Pyrus (Sorbus) occidentalis. A shrub, 2 feet (Sulsdorf) to 

 4 or 6 feet high (Brewer), glabrous or very nearly so : leaflets 3 or 4 

 (very rarely 5) pairs, oblong-elliptical, obtuse, sometimes mucronate, 

 dentate usually only toward the apex (rarely below the middle) or 

 sometimes entire, 1 to 2 inches long, the rhachis 3 or 4 inches lono-; 

 cyme small and usually rather few-flowered : calyx glabrous: fruit 

 pyriform, red, 4 lines long : seeds semicircular in outline, 1^ lines long. 

 — In the mountains from Washington Territory to California (Cas- 

 cade Mountains, Lyall ; Mt. Adams, at 5-6,000 feet altitude, Suksdorf ;
