Hamosi. 260 



keel. Keel about 3 mm. long, nearly straight then abruptly erect 

 and tip a little out-turned and acutish, nearly 3 mm. hig-h, about 

 equaling: the calyx tips, purple-tipped. Calyx tube about 2 mm. 

 long, acutish and a little oblique at base, about equaled by the subu- 

 late teeth, nigrescent. Pedicels very short and bracts minute. 

 Peduncles filiform, rather shorter than the leaves, 2-3 cm. long, axil- 

 lary, hardly as long as the fruiting rachis. Leaves 3-4 cm. long, 

 with the petiole nearly ps long as its rachis, many but open. Leaf- 

 lets 4-5 pairs, rather obovate, often notched, nearly 1 cm. long, 

 not contiguous. Stipules small. Stems very slender and flexuous, 

 v.-eak and spreading, branched, apparently from slender underground 

 stems from a perenial root, but possibly winter annuals, about a 

 foot long. Blooming in May. John Day river Oregon Howell. 

 Middle Temperate life zone. 



224. Astragalus Congdoni Watson Proc Am. Acad. 20 360 

 (1885). Pods minutely pubescent when mature, densely so and 

 often nigrescent when young, shortly acuminate and inclined to 

 have tip declined, reticulate, loosely racemose, closely reflexed, about 

 2 cm. long, and 2-3 mm. wide and high, rather cordate in cross 

 section, tPie ventral suture thick and with sharp edge along the 

 middle, barely acute at base. Flowers white, narrow, rather closely 

 racemose, reflexed. Banner oblong-ovate, about 1 cm. long, arched 

 abruptly about 2 mm. beyond calyx tips to 45^, with sides re- 

 flexed about 1 mm. wide below, nearly 5 mm. longer than wings. 

 Wings oblong, arched 30% about 2 mm. longer than keel. Keel 

 about 4 mm. long and high at tip, the base proper about 1 mm. 

 long, the rest a rather deltoid erect and acutish not darker tip 4 

 mm. high. Calyx tube about 4 mm. high inserted near the lower 

 corner on a stout black pedicel, black-woolly, teeth rather shorter 

 than the tube, subulate from a broad base, the lower the longer. 

 Pedicels almost none. Bracts hyaline, triangular, about 3 mm. 

 long. Peduncles about 1 dm. long, sulcate and stout mostly, as long- 

 as or shorter than the fruiting rachis, erect. Leaves 5-10 cm. 

 long, narrow and tapering, the upper sessile or short-petioled, the 

 middle ones the largest, with 8-10 pairs of leaflets 1-1.5 cm. long 

 which are contiguous, softly silky with hairs often tangled. In- 

 tei-nodes congested below and stems very leafy. Stipules green, 

 large, deltoid. Stems decumbent, slender, about a foot long, 

 rather simple but with many woody branches at base. Fisher's 

 Cabin and Hite Cove in the Sierras. Middle Temperate life zone. 

 This grows ,in rocky places and blooms in May and June. Collected

225. Astragalus Andersoni Gray Proc. Am. Acad. 6 524 

 (1865). Pods 1.5-2 cm. long 3-4 mm. high, about 2 mm. wide, 

 narrowly-oblong to neaiiy linear, triangulai'-acute to blunt and 

 apiculate, nearly straight to arched to one-thii'd circle, mostly a 

 little reflexed, rounded at base, early falling off and leaving the 

 empty calyx, with ventral suture raised and thickened and sharp 

 along the middle, splitting the calyx, 1-cclled at tip, with cross 

 section narrowly to broadly cordate, narrowly sulcate dorsally, 

 softly and variably silky-woolly. Flowers normally white but often 

 pink or tinged with pink, short and stubby, broad, in heads at 

 first or spicate and ascending, later inclined to horizontal. Petals 

 very thin, rather translucent. Banner oblong-ovate to oval, 6-8 

 mm. long, arched abruptly at end of teeth to 45° or rarely erect, 

 with sides reflexed about 2 mm. wide below, about 4 mm. longer 

 than wings ; groove U-shaped below, and V-shaped above ; white 

 spot striped when present, wings oblong-obovate, very oblique, 

 acutish, about 2 mm. wide, notched, concave to keel and touching 

 beyond it, purplish below and white above or all white, 1-2 mm. 

 longer than keel, inclined to be oblanceolate and wavy toward tip, 

 variously arched. Keel about 4-5 mm. long and 3 mm. high, half- 

 cuneate obovate and with tip obliquely truncate, purple above. .
