densely hirsute with spreading brownish hair which conceals a fine 
surface pubescence and passes into a close hoary pubescence in the 
racemes; in immature plants the hairiness is very dense and sub- 
appressed, the young branches and racemes densely canescent- 
Pilose. Leaves bright green, numerous, mostly spreading, but 
often the lower leaves are deflexed, those above spreading, the 
upper ones rapidly diminished in size and ascending or erect, 
mostly oblong to narrowly-oblong in general outline, 4’-12’ long, 
2'-7 4! wide; leaflets commonly {1-17,or sometimes as many as 
twenty-three on the narrowed lowermost leaves, strongly-nerved and 
rugose, minutely petiolulate or sessile, spreading, the distal pair 
obliquely contiguous to the odd one and often decurrent on the 
leafstalk, the lower pairs frequently somewhat alternate, lanceolate, 
sometimes narrowly lanceolate, tapering to either end, acutefy ser- 
rate, 1’-41/’ long, 4-14” wide, a common size being 24’ X 8’’-9”, 
above obscurely hispidulousto glabrous, usually finely scabrous near 
the edges, the margins minutely ciliolate, paler below and thinly to 
softly pubescent, with longer appressed or spreading often brown- 
ish hairs on the nerves and sprinkled with minute shining glan- 
dules. Leafstalk villous, tomentose-pubescent on the upper side. 
Interposed leaflets crowded, mostly 4-5 pairs except in the lowest 
interspaces, often subopposite, mostly narrowly oblong and sessile 
by a broad base, the main pair sharply serrate to below the mid- 
dle, separated by only a minute pair from the succeeding pair of 
leaflets, the others gradually smaller, all but the most minute 
sharply-toothed. Stipules, except the reduced lower ones, 
broadly cordate-amplexicaule, sometimes 1’ broad, the outer mar- 
§1n serrate or cut-serrate, deeply cleft at the tip into a narrow at- 
tenuate lobe sometimes 1’ long, which stands either abruptly 
€rect against the stem or is bent sharply backward. Racemes 
glandulose beneath the pubescence, mostly erect or sharply as- 
cending, 10’-21’ tong, many-flowered. Flowers 3/’-5” broad, 
rather pale yellow with thin narrow petals; anthers small with 
broad connective. Bracts very small, pilose-pubescent, the lobes 
filiform ; bracteoles very small, trifid. Flower-buds very small, 
somewhat obovoid and subtruncate, slightly mamillate, somewhat 
glandulose, sepals ovate-oblong, acute. Fruit small, nodding on 
slightly spreading pedicels, 1-2” wide and long, minutely glandu- 
lose; the slender stipe-like base slightly strigose, the body subglo- 
bose, short-turbinate or hemispheric below the bristles, the disk 
much elevated; bristles medial on the fruit, the outer short and re- 
flexed, the innermost erect, equalling or exceeding the broad sub- 
truncate calycular process. Base of the stem bulbous-thickened in 
the form of an oblong tuber sometimes nearly 1’ in diameter. Roots 
not tuberous-thickened. ee ee ane 
Comes into flower from the middle to the end of July, continu- 
ing to bloom till about the middle of September. .
