 GreeneiGtvy P. A. A. xvi 105.) 



Astragalus gracilentus var. fallax (Wat.) (A. fallax 

 Watson P. A. A. xx 362) is a form with larger flowers and short 

 calyx lobes. 



Astragalus Fcndkri Gray PI. Wright ii 44 is a synonym of 

 A. flexuosus Dougl. Hook. Fl. Bor. Am. i 140. Watson con- 

 fused this with the gracilentus forms in P. A. A. xv 362. 



Astragalus Pinonis, n.sp. Frisco, Utah, June 22, [880, at about 



8000 ft. alt. among junipers and pinons, in gravel. Perennial, 



rather slender, ashy-puberulent throughout, nearly erect, stems 



branched below, rounded and flexuous, about 6 inches high, nodes 



usually 6 to 9 lines apart; stipules triangular, small, a line or less 



long, not membranous, distinct; leaflets linear, rounded at both 



ends and barely petiolulate, 4 to 10 pairs, 6 lines long, a line 



wide, not contiguous, leaves 2 to 3 inches long, all short-petioled; 



proper peduncles 1 to 2 inches long, shorter than the leaves, 



slender, racemosely few-flowered, the rachis equals the peduncle 



or is halt as long; fruit pendent on 2-lines— long, slender 



pedicels; bracts triangular, half a line long; calyx campan 



ulate, narrowed below, the tube a little over a line long, 



subulate teeth half the tube; flowers probably purple; keel 



about two lines long and purple tipped, tip abruptly erect, 



straight, acute, produced, nearly 1% lines high, ^ line wide at 



base, equaling the oblong wings; banner oval about as long as 



keel; these are not fresh flowers, being only fragments on the 



pods; pods straight, short-stipitate, linear-oblong, shortly acute 



at both ends, a little larger above, 2 lines high and nearly as 



wide, 9 lines long, corrugated, somewhat inflated, coriaceous, 



both sutures narrow and rounded externally, the ventral 



a trifle raised, neither suture at all intruded and pod wholly 



r-celled, ventral side nearly straight, dorsal convex. This 



has the appearance of A. atratus but the pod is nearer A. 



Pattersoni. This has remained unpublished for 17 years with 



the hope of finding good flowers and more ample material, but 



it has not been seen yet.
