Aeschynomene vigil Brandegee. Shrubs about a yard high, rather 

 intricately short-branched much as in Amorpha canescens, the leaves being 

 clustered on the last few inches of the hoary twigs. Pubescence closely 

 appressed on the stems, and dense, much less so on the leaves, of slender 

 and flexuDus hairs. Leaves about 2 cm. long, rather hoary, of 4-5 pair* 

 of oblong leaflets, about 8 mm. long, obtuse to emarginate, with the mid- 

 rib off from the center, and the central leaflets the largest, the terminal 

 one often twin. Flowers in very short axillary racemes, 1 to 3, sessile 

 near the ends of capillary peduncles, which are not over 1 cm. long. 

 Flowers very dark-purple, with yellows-tipped keel, the banner hairy and 

 alx)ut 5 mm. long, and very broad. Calyx strigose, with triangular-subu- 

 late lobes. Legumes of 1-3 joints which are half-rhombodial, the stipe side 

 straight, reticulated, sparsely short-hairy, almost contiguous, about 5 mm. 

 long and 3 mm. high. No. 24260. Miraflores, Lower California, Febm*
