1. Wislizenia melilotoides Greene, 1. c., p. 130. 
Glabrous, stout and low, freély and somewhat fastigiately branched, 
all the branches short, very leafy, ending each ín a short subsessile ra- 
ceme: leaflets cuneate-obovate, very obtuse, almost truncate, mucronulate, 
1—2 em long: fruiting racemes narrow, the oldest only 5—7 cm long: 
fruit 4 mm wide; carpels long-pyriform, remarkably smooth and rounded, 
at most only obscurely lineolate and with traces of two or three tubercles, 
more usually with none at all. 
Vieinity of Holbrook, northern Arizona, apparently first collected 
by H H. Rusby, August 20, 1883, no. 581 as in U. S. Herb.; again at 
Hardy Tank in the same region, by E. O. Wooton, 1892; the most per- 
fect specimens by Miss Myrtle Zuck, at Holbrook, August 4, 1896. 
In habit, form and hue of the very copious foliage, and short racemes, 
this species strongly recalls a yellow-flowered Sweet Clover. Its fruit 
characters are very strong, the carpels being usually quite smooth, and
