NEW SPECIES OF CALIFORNIAN PLANTS. 425 



on slender petioles about 4 cm. long; leaflets 4-7, nar- 

 rowly oblanceolate, 15 mm. long, 2 mm. wide; stipules 

 linear-acuminate, 9 mm. long, half attached to the petiole; 

 peduncles slender, 3—4 cm. long, surpassing the leaves; 

 verticels 3—5, not clearly defined, with varying internodes 

 (lowest 2-3 cm. long); bracts nearly equalling the calyx, 

 early deciduous, herbaceous; calyx i-lipped, somewhat 

 hood-shaped, 3-crenate at apex, with a shorter crenature 

 on each side; banner white, edged and spotted with blue, 

 unchanged after pollination, ovate-spatulate, 1 cm. long, 

 surpassed by the conspicuous rostrate keel which is 

 slightly pilose on the outside; wings equalling and adher- 

 ing to the keel so as to seem a part of it ; both are white 

 below, tipped with blue, which becomes purplish after 

 pollination; pods 4-5 seeded, slightly erect-falcate, with 

 silky hairs appressed and shining; seeds white, quadrate, 

 with rounded corners. 



This elegant little Lupine belongs to the same section 

 as micranthiis, polycarftus and trifidus. It differs from 

 all in the peculiar i-lipped calyx and the long-beaked 

 keel. It somewhat resembles L. polycarpus, in the in- 

 florescence, but the flower is quite distinct from that 

 and all other members of the group. The pubescence 

 is similar to that of L. micranthus. 



It is named from the conspicuous rostrate keel which 

 persists with the similar wings, adding spots of purplish 

 blue to the silky-canescent pod. 



Mr. L. Jared discovered this interesting Lupine near 

 Estrella, in San Luis Obispo County, and he also detected 

 its specific characters. He first noticed it in 1895 ; this 

 year (1896) he has found it in several places, eight or 

 nine miles apart. He writes that the beaked appearance 

 of the keel and wings is so marked that he can always 

 readily distinguish the species even when riding by.
