k0. Hedysarum canescens (Nutt.! mss.): 
«stems numerous from the same root, erect or decumbent, minutely canescent; leaves on 
short petioles; leaflets #—6 pairs, narrowly oblong or cuneate-oblong, canescent; stipu- 
les very small, sheathing, with subulate points; racemes short; the peduncles longer 
than the leaves; wings much shorter than the keel; joints of the legume 3—%, oval-or- 
bicular, nearly glabrous, transversely rugose-reticulated.» 
«Plains of the Rocky Mountains, particularly near Lewis's River. — Plant (—2 feet 
high: stems decumbent at the base, stout, branching.» Nuttall. —  Racemes at length 
elongated. Flowers somewhat spreading (reflexed in fruit), about the size of those of 
H. boreale. Teeth of the calyx narrowly subulate, rather longer than the tube. — Inter- 
mediate in some respects between the two preceding species (H. boreale et H. Mackenzii).
