lower leaves small, upper the largest, these are oval to obovate,

I can see no character to surely separate this species from A. 

 diphysiis Gray, and it is not at all certain that it is distinct from. 

 A. Coulter i. 



Astragalus lentiginosiis Douglas. A plant collected at 

 Alcalde, Cal., 1890, by Mr, Brandegee would fall under the 

 variety Fremonti. It is evidently' perennial, one and one-half 

 feet high, erect, whole plant tomentose-canescent, sparse above; 

 calyx densely black-hairy, cylindric-campanulate, three lines 

 long, a line wide, teeth one-third the tube; flowers ochroleucous, 

 five lines long; peduncles a little surpassing the leaves, densely 

 ilowered; pods very shortly stipitate and jointed at tip of stipe, 

 sparsely hairy; leaflets about ten pairs, obovate; no petiole above. 



Astragalus latus (A. diphysus Gray var. latus Jones, Zoe iii, 

 287). It is manifest that this is a distinct species as I have had 

 a chance to stud}- it this season from the beginning of its develop- 

 ment to the end. It forms a loose mat on the ground, which 

 is from one to two feet in diameter, the stems are short and the 

 leaves long, the peduncles only half as long as the leaves and 

 so the flowers are hid among the leaves, calj^x thickened at base 

 and the lower side the longer but straight, hyaline, white, 

 sprinkled with minute black hairs, four lines long, one and one- 

 half lines wide and a line thick, not bent nor uneven in width, 

 cleft deeper above, teeth unequal, subulate, about a line long, 

 inclined to spread; banner usually with sides not reflexed, ovate, 

 four to six lines wide in the middle, bent abruptly at tip of calyx 

 teeth at an angle of 45°, six lines longer than calyx, deeply 

 notched at tip, thin and not thickened at base, light pink-purple, 

 occasionally the outline of the banner is oblong, triangular or 

 even fiddle shaped by the varying position of the sides; sulcus 

 conical, and very small at its apex the tip of the keel; white 

 spot obovate, cut up by radiating purple veins, reaches within 

 one and one-half lines of the tip; wings narrowly oblong oblan- 

 ceolate to broadly oblanceolate, rounded at apex which is often 

 considerably enlarged, minutely notched on the lower side near 

 the apex, one and one-half lines longer than the keel and purple 

 at apex and lighter below, ascending 45°, concave to keel and
