6, L. oblongifolius Greene. Stems bright green, 1.5 to 3 dm. high, 

 arising from a slender rootstock ; herbage appressed-pubescent ; leaflets 

 linear-lanceolate or elliptical, acute at both ends ; umbels 1 to 5- 

 flowered, borne on peduncles exceeding the leaves ; bract of 1 to 3 

 leaflets; flowers 8 mm. to 1.5 cm. long; calyx tube short-turbinate, 

 somewhat villous ; banner yellow more or less veined with purple ; 

 claws of petals scarcely exserted beyond calyx tube, the broad obtuse 

 blade of keel longer than the claws. 



Common in damp or wet situations in the foothills and mountains 

 of southern California, passing into the variety torreyi in the southern 

 Sierra Nevada. Distribution Map 2. May-October. The plants with 

 the narrowest leaflets and the fewest flowered umbels are evidently 

 the same as Hosackia lathyroides Dur. and Hilg. They doubtless 

 represent only the first season's growth and have not yet developed a 

 perennial rootstock, as for example, Abrams' 1879 from the San 

 Gabriel River and Vought's specimen from the head of San Joaquin 

 Valley. Elmer's 3975 from Mt. Pinos possesses a very short rhizome, 

 otherwise closely resembling the collections cited above.
