172 : PITTONIA. 
small, in racemes of 4—7 distinct verticils ; pedieels a line 
long: upper calyx-lip bifid, its ovate teeth short, straight and 
parallel, the lower scarcely longer, 3-nerved, slightly notched 
at apex: corolla 13 lines long, deep blue, the middle portion 
of the obovate retuse slightly reflexed banner white and dark- 
blue-dotted ; wings coherent at the tips, below them distinctly 
obcompressed, exposing the base of the keel ; keel broad and 
short, ciliate above the middle and below the short blunt 
retuse apex: pod rigid, slightly falcate, tardily dehjscent, 
T-seeded : seeds obliquely oval, 14 lines long, uniformly dull 
dark brown, or oceasionally paler and with some marblings of 
very dark brown. 
The commonest of all lupines in the vieinity of San Fran- 
cisco, in low, rich ground, flowering and fruiting in May. On 
account of its minute and inconspicuous flowers, the charac- 
ters of which, excellent though they are, are not obvious in 
the dried specimen, the species has hitherto been confounded 
with the very different L. micranthus ; but it is really more 
related to the coarse fleshy large-flowered L. affinis, which it 
resembles in habit, pubescence, texture and other points. 
TRIFOLIUM QUERCETORUM. Annual, slender, a span high, 
glabrous and pale green, the stipules, involucre and calyx 
searious and green-veiny : leaflets a half-inch long, cuneate- 
obovate or -oblong, truncate or retuse, spinulose-serrulate, on 
slender petioles of an inch long or more: peduncles slender, 
a little exceeding the leaves; involucre cyathiform, about 
5-lobed, the lobes rounded, entire or few-toothed, the green 
veins not pervading the broad scarious margin, 3—5-flowered : 
corolla yellowish, 2—3 lines long, inflated in age : calyx teeth 
lanceolate-acuminate, entire, the lower twice or thrice as long 
as the upper, far surpassing the involuere and nearly equalling 
the corolla. 
The name Trifolium fucatum, as employed in the Botany 
of California, embraces about three different plants which 
ought to be separated, and which, indeed, were separated, I
