The genus Fendlerella is not very distinct from Whzpplea in 
-floral-and fruiting characters, but differs very much in habit and 
leaves. The leaves of F. Utahensis, like those of 7. Mexicana, 
break away, leaving’a base silky-hairy in the axils; this char- 
acter is especially evident with F. Mexicana, for the leaves are 
soon deciduous, the nodes are only 3-4 mm. apart, and the long, 
white silky-hairs give a gray appearance to the otherwise naked 
branchlets. The base of some stems is 1 cm. thick. Collected 
on rocky slopes of Cerro de Baxtle, Puebla. No. 2588. 
Rhynchosia prostrata. Caules prostrati ramosi pubescenti 
radice valida 1-1.5 dm. longi: foliolis 3, orbiculatis mucronatis.

diametro 1 cm; petiolis 5-12 mm. longis: stipulis lineari-lanceo- 
latis 3 mm. longis: floribus solitariis flavis 4-5 mm. longis; pen- 
dunculis axillaribus 1 cm. longis: calycis segmentis lineari-lan- 
ceolatis tubo zequilongis: leguminibus 18 mm. longis: seminibus 
2 compresso-globosis.

which this species is closely related. Collected at Esperanza, 
Puebla. No. 2479.
