pubescent to nearly glabrous) with longer usually subappressed 
brownish hairs on the nerves and freely sprinkled with minute glis- 
tening glandules, in shape lanceolate to elliptic or ovate-elliptic, ta- 
pering from near the middle to either end, often decidedly tetragonal 
or rhomboid, acuminate or very acute, sharply serrate with mucro- 
nulate often deeply cut teeth (rarely with broader even subcrenate 
teeth), the narrowed base and acuminate apex often entire, usu- 
ally petiolulate or the distal pair sessile and decurrent, the odd 
leaflet sessile or on a foliolate stalk and frequently pinnatifid at 
the base, the lateral leaflets more rarely basally pinnatifid, but 
never on the lower side in the distal pair. A common size of 
the leaflets is 2’ x 3/’, and extreme size 314’ X 114’ (on the lower 
leaves the leaflets are often shorter and less pointed with more 
deeply cut narrower teeth). Interposed leaflets 2-7 pairs, fre- 
quently subopposite, narrow, often linear-oblong, the main pair 
dentate-serrate above the middle, the others much smaller or 
minute, entire; not seldom a minute pair subtends a pair of 
leaflets like a set of stipels. Stipules lanceolate to half ovate, 
laciniate or cut-lobed, the terminal lobe broader and acuminate 
sometimes with one or two teeth on the inner margin. Main 
racemes 12/18’ long, obscurely pulverulent beneath the pubes- 
cence, densely flowered except near the base, some of the 
flowers often subverticillate-clustered, rarely loosely flowered, 
erect or ascending, at maturity often declined from the weight 
of the abundant fruit. Flower-buds mammillate; flowers 3/’-5” 
wide, shorter-pedicelled than in /zrsuta, the petals more rounded, 
mostly thicker and deeper yellow; anthers smaller with narrower 
connective; bracts smaller and less ciliate; bracteoles ovate, 
short-acuminate, entire or slightly lobed. Mature fruit closely 
reflexed against the pedicel and stem, large, 2-3’ broad, i ig 
4” long, rather long-turbinate, the walls thickened and muc 
indurated, strongly fluted between the deep furrows, minutely 
puberulent-granular and with traces of appressed hairs, the furrows 
strigose-canescent; disk becoming flat or concave, marginless ; 
bristles numerous, short, one-quarter to one-third the length of the 
fruit, at first ascending and erect, finally connivent in a conical 
mass over the concealed calycular process. Sepals less acuminate 
than in zrsuta and more canescent within the tip, the apex at ma- 
turity scarcely hooked. The tips of the bracts, sepals and bristles 
with the callosities tipping the teeth of the leaves early become 
tinged with reddish-purple. Rootstock much as in /ursuta, but 
even stouter, the long roots as in that species slightly thickene 
throughout and not tubiferous. (Plate 282, fig. 2.)
