40. L. benthamii llol. Spider Lupine. Stems 1 or several from the base, 

 slender, rarely branched except at base, 1 to 2 feet liigh; herbage thinly hirsute, 

 the stems and petioles also puberulent; stipules lincar-setaceous; leaflets 7 to 10, 

 narrowly linear or filifonn, glabrous above, % to 2 inches long, half as long as the 

 very slender petioles; racemes 4 to 10 inches long; young tips of racemes conspicu- 

 ously plumose by virtue of the villous bracts, the.se exceeding the buds, linear, 6 to 

 8 lines long, caducous; flowers 5 to 6V2 lines long; cahrx subsaccate or gibbous at 

 base on upper side; lower lip narrow, 3-toothed at apex; upper lip deeply cleft into 

 lanceolate lobes; petals 5 to 5V2 lines long, bluish-lilac, the large j'ellow or white 

 spot of the banner changing to deep crimson or purple; keel slender, glabrous on 

 upper margin, slightly ciliate on lower margin near claw; pods % to li/4 inches 

 long, 4 to 7-seeded, % to 1^4 inches long. 



Open hills and rocky slopes, often in very thin stands of oaks, 200 to 2500 feet: 

 Sierra Nevada foothills from Placer Co. to Kern Co.; coastal region from Monterey 

 Co. to northern Los Angeles Co. Apr.-June. 



Foliage. — The leaflets are stellately disposed horizontally from the summit of the petioles. 

 Being narrow and trough-like they have, extended so, a "spidery" effect not seen in other species. 

 The leaflets are spaced almost equally around the circle; when a little unequal sometimes the gap 

 is greater at the morphological base of the leaf-blade, sometimes it is greater elsewhere.

 individuals, usually with larger flowers, but without any constantly associated set of characters. 



41. L. sparsiflorus Benth. Coulter Lupine. Plants 1 to 1^/^ (or 3) feet high, 

 the stem sparingly or much branched; herbage puberulent and also with scattered 

 stiff hairs; leaflets 5 to 9, oblong-oblanceolate to linear, 3 to 12 lines long, the shortly 

 acute apex recurved, 4 to 12 lines long; petioles I/2 to 2 inches long; racemes slender, 

 dense, or sometimes lax, 2 to 9 inches long; flowers 4 to 6 lines long, spreading in 

 an thesis, afterwards ascending; bracts linear-setaceous, shorter than the calyx, 

 subpersistent ; pedicels 1 to 1^/2 lines long; upper calyx-lip deeply 2-parted, the 

 lower truncatish and apiculate or 3-tootlied; petals violet or lilac; center of banner 

 dull white, changing to a bright red-purple; keel glabrous or ciliate on upper side, 

 usually ciliate toward the base on the lower side, its point slender, upturned at

Note on variation. — The described varieties have been furnished with a key by C. P. Smith 

 (Bull. Torr. Club 47:494) based upon a few obvious characters but free use of the key often 

 assembles unlike things in the varieties. The varieties are much disturbed by cross-currents, the
