14. A. leptoclada Greene. Stems few or several, radiating horizontally from 

 the root-erown, prostrate but with the tips ascending, 2 to 7 inches long, flowering 

 from below the middle or from near the base ; herbage somewhat succulent, glabrous 

 or weakly hirsutulose ; leaf-blades linear, % to 41/2 inches long ; spikes loose, 1 to 5 

 inches long ; calyx slightly fleshy, cleft i/o or %, accrescent in fruit and 2 to 3 lines 

 long, the tube 5-ribbed; corolla i/^ line broad ; nutlets ovate or lanceolate, contracted 

 slightly above the middle and the upper portion obcompressed; dorsal side of nut- 

 lets finely papillate and sparingly rugulose, otherwise smooth or sometimes with 

 hairy-tufted bristles; ventral side keeled and weakly or obscurely rugulose or 

 granulate ; scar exactly basal, circular and usually separated from the body by 

 a slight constriction.

15. A. humistrata Greene. Stems few or several from the base, mostly pros- 

 trate, flowering from near the base, 3 to 12 inches long; herbage subglabrous or 

 thinly puberulent; leaf -blades linear, V2 to 1 inch long; spikes 2 to 4 inches long, 

 the flowers remote ; pedicels stout, in age commonly deflexed ; calyx markedly ac- 

 crescent, in fruit 3 to 5 lines long, the lobes "turned to one side, standing vertically 

 in a row;" nutlets ovate, the dorsal side unequally or scantily tuberculate and short- 

 rugulose, sparingly provided with short processes bearing a tuft of microscopic 

 bristles ; ventral side keeled, obliquely and rather regularly rugulose or sometimes 

 very sparingly rugulose; scar ovate or somewhat deltoid, lateral but reaching 

 the base.

Refs. — Allocaeya humistrata Greene, Pitt. 1 :16 (1887), "San Diego throughout the state." 

 This description covers what is now accepted as two species but it applies, argues C. V. Piper 

 (Contrib. XJ. S. Nat. Herb. 22:92) "much better" to the plant at Antioch, also included by Greene 

 in his description, than to the plant at San Diego. Collections had been made at Antioch, lower 

 San Joaquin Valley, by M. K. Curran in 1884 and by E. L. Greene on Apr. 7, 1885. Greene's 

 Antioch collection, the part of it preserved in his own herbarium, were, therefore, better taken as 

 the type. The collection of Curran in the California Academy of Sciences Herbarium was, to be 

 sure, also examined by Greene, but the notation "type" on the specimen was written by M. K. 

 Curran (K. Brandegee). The foUowing synonymy here finds place: Plagiobothrys humistratus 

 Jtn., Contrib. Gray Herb. 68:77 (1923). A. limicola Piper, Contrib. U. S. Nat. Herb. 22:97
