LUNDELL: THE GENUS PARATHESIS 141 
isotypes), shrub 4 m., fl. pink; Tancitaro, canyon 2 mi. east of Tancitaro, elev. 6000 ft., July 21, 
1941, Wm. C. Leavenworth & H. Hoogstraal 1068 (F, MO). Stnavoa: without locality, collected 
in 1920 by the Comision Catastral y de estudios de los recursos naturales del estado, 964 
(LL, US). 
Usually the floriferous branchlets have reduced leaves apically so that the 
axillary inflorescences appear terminal. The villous indument of the inflores- 
cences, leaves pubescent at first on lower surface with fine sessile stellate hairs, 
large sepals, and flowers with all parts conspicuously punctate, including fila- 
ments and style, together with the strongly depressed-globose placenta with 
8-10 ovules are features of P. villosa. 
Although it varies more than usual in size of flower parts, pubescence of 
apical internodes and in the degree of pubescence of the ovary apically, this 
should be expected when the range and diversity of habitat of the species is 
considered. The type of pubescence is typical in all specimens cited.
