obtuse at both ends but prominently mucronate, alternate on 

 a filiform rachis ending in a branched and well developed ten- 

 dril ; stipules of lower leaves semisagittate, the lobe with a 

 few subulate teeth, the main part entire, of middle leaves nar- 

 rowly lunate, very acute and entire, the lobe of about equal 

 length with the main part, whole plant glabrous to the naked 

 eye, but a scattered villous hairiness visible under a lens, 

 chiefly along the rachis and about the stipules : racemes not 

 equalling the foliage, about 5-flowered, the flowers 54 inch 

 long, narrow, purple. 



Var, i.ATiuscui,A. Leaves only % inch long, oblong-linear 

 and even oblong, subtruncate, mucronate ; flowers fewer in 

 the raceme, only V^ inch long. 



From an elevation of 7500 feet in the mountains of middle 

 Arizona, 16 June, 1912, A. D. Read ; the type and the variety 

 growing together, even with intermediates, but all alike as to 

 color, texture and indument of herbage. 



ViciA HYPOLASiA. Stature and habit of the last, leaflets 

 also 10, but more crowded on their rachis, % inch long or 

 very little more, lance-oblong, obtuse, only minutely mucro- 

 nate, of a rather vivid green and thinnish texture, under a lens 

 notably feather-veiny on both faces, glabrous above, not very 

 sparsely villous-hairy beneath, more especially towards the 

 midvein : racemes quite surpassing the leaves, 4-flowered ; 

 corolla more than % inch long, narrow only below the strongly 

 developed and suberect banner, the wing petals unusually 

 short : pods little more than 1 inch long, tapering to both 

 ends, about 3-seeded, transversely flexuous-veiny.

 acute, color of herbage pale glaucous-green, nearly or quite 

 glabrous : leaves of about 10 leaflets 1% to 2 inches long, very
