A. douglasii var. piscinus Jones, Contrib. W. Bot. 10:61 (1902). Phaoa piscina Eydb. N. Am. 

 Flora 24:345 (1929). 



8. A. douglasii Gray. Dobie Loco. Stems many, ascending or decumbent, 

 ll^ to 3 feet high; herbage appressed-pubescent or in age glabrate; leaves 3i/^ to 

 61/4 inches long; leaflets 15 to 25, linear to oblong-linear, obtuse or retuse, 4l^ to 

 12 lines long; racemes 1 to 2 (or 3) inches long, commonly loose; flowers spreading, 

 3 to 4 lines long; calyx-teeth subulate, I/2 to % as long as the campanulate tube; 

 corolla white, yellow or greenish; pods remarkably inflated, oblong to ovate, ab- 

 ruptly very short-acute, thinly pubescent with short straight hairs or in age gla- 

 brate, 1-celled, 1 to 2 inches long, the ventral suture slightly intruded; seeds many. 



Dry adobe or sandy flats, slopes or gulches in the hills, 180 to 4000 feet : western 

 Yolo Co.; lower San Joaquin Valley plain; South Coast Ranges; Tehachapi Mts.; 

 mountains of Southern California. May. 



Note on variation. — The fruiting racemes are sometimes few-podded and loose, or some- 

 times many-podded and dense, with every gradation between. Throughout the range of the species 

 the pods are commonly or often about one inch long, varying to two inches in length. Indifferently 

 in the large-podded or small-podded states we find the seed-bearing suture barely intruded 

 (Cahuilla Valley, sw. Riverside Co., Jepson 1472), slightly intruded (betw. Mossdale School and 

 Atlanta, San Joaquin Co., Jepson 13,744), or intruded nearly 1 line (Bates sta., Fresno Co., 

 Jepson 12,909). This character has, therefore, no importance in differentiating the species and 

 its forms. If Astragalus douglasii be evaluated as to its outstanding characters and the features 

 disregarded which are in the main individual or obviously fluctuating, we find a unit which is 

 satisfactorily natural as above diagnosed. The specimens cited below may be regarded as fairly 

 typical of the species.

Var. parishii Jones. Plants more robust than in the species, 1% to 3% feet high; leaflets 

 oblong, 4 to 9 lines long; peduncles l^/^ to 3% inches long, about equaling the racemes; banner 

 scarcely exceeding the wings; pods 1% to 1% inches long. — Laguna, San Bernardino and San 

 Gabriel mountains to the Tehachapi Mts., 4000 to 6700 feet. 



Tax. note. — With the accumulation of material the differences between Astragalus parishii 

 Gray and A. douglasii Gray have been reduced to a matter of size except for the shape and 

 relative size of the petals. In extreme forms the banner of A. parishii is broader than in A. 

 douglasii; it exceeds the wings by about % line, in A. douglasii by about 1^^ lines. Variation in 

 the one species, however, as to all organs, is about as great as variation between the two. Astra- 

 galus parishii is, therefore, accepted here only as a variety and should, doubtless, be reduced to 

 complete synonymy.
