Type species: Trichloris pluri flora Fourn. 
Trichloris Fourn., Mex. PI. 2 : 142. 1886. Founder includes two species, 
T. fasciculata and T. pluri flora, both described as new. In the generic descrip- 
Fig. 112. — Chloris virgata. Plant X \ ; glumes and floret with rudiment, X 5. 
tion occurs the statement " flore sunmio tabescente mutico." Under the second 
species one finds " flore summo mutico." From this it would appear that 
T. pluriflora represented Founder's idea of the genus; hence this species is 
selected as the type.
