LEGUMINOSAE 



Field note. — This narrow ranj;e species probably has its center of distribution and greatest 

 development in the mountains between Tejon Pass and the upper Santa Clara River. The 

 numerous stems from the root-crown, partly erect and partly spreading, branch low, thus forming 

 dense clumps 10 to IS inches high and 2 to 4 feet broad.

 near Frazier Borax Mine, Mt. Pinos, Ventura Co., 

 Ahrams 4' McGregor 219; a sjTionym as evidenced by 

 the type specimen (N. Y. Bot. Gard.) ; Rydberg says 



"pods linear-elliptic", but they do not differ from the >A^.Krf\ G 



usual or prevailing form. 



42. A. trichopodus Gray. Coast Loco. 

 Steins riprid, erect, 1 to 3 feet high; herbage 

 thinly strigose-puberulent or the upper surface 

 of the leaves glabrous; leaves 3 to 5^^ inches 

 long; leaflets numerous, narrowly oblong or 

 cuneate-oblong, obtuse to retuse, 3 to 6 (or 7) 

 lines long; racemes short, commonly dense, the 

 peduncles commonly shorter than the leaves; 

 pedicels recurved in fruit; flovrers 4 to 6 lines 

 long; calyx-teeth triangular-subulate, % as 

 long as the campanulate tube; corolla yellovr- 

 ish-white; pods compressed or somewhat in- 

 flated, mostly semi-elliptic with the ventral 

 suture nearly straight or a little convex, acute 

 at base and apex, 1-celled, glabrous, 6 to 11 

 lines long, 3 to 4i^ lines broad, pendulous on a 

 filiform minutely pubescent stipe 3 to 6 lines 

 long. 



Caiions or mesas in the immediate coastal region, 50 to 1000 feet : Santa Barbara 

 Co. to Orange Co. May-July. 



Variation. — The pods differ much in size, varying in various collections from ^/^ to IVq 

 inches long. There is also some variation in shape : 1. Pods with the ventral margin straight or 

 only slightly curved, the dorsal suture strongly curved (Santa Catalina IsL, Trash; Santa Ana 

 Canon, Orange Co., J. T. Howell 2415 ; Gaviota, Santa Barbara Co., Eastwood) . 2. Dorsal margin 

 less markedly curved (La Brea Canon, Puente Hills, T. W. Minthorn) . 3. Ventral margin with a 

 long low curve, the dorsal margin rather strongly curved, the pods short, 5 to 7 lines long (Santa 

 Barbara, Eastwood) .

 by the type specimen (Univ. of Minn. Herb.) and not the equivalent of A. antisellii Gray as said 

 by Rydberg (N. Am. Fl. 24:274), a species which belongs in a different climatic region. 



43. A. cimae Jones. Cima Loco. (Fig. 212.) Stems several from the root- 

 crown, branching, diffuse, 10 to 12 inches high; herbage glabrous; leaves 2 to 5^ 

 inches long; leaflets 11 to 19, broadly ovate or suborbicular, obtuse, 7 to 10 lines
