nated basal lobes; the outer series of bristles is y 8 m length 

 of the inner one; V. angustissima has the corollas divided only 

 to one fourth of the length, the anthers are linear with short 

 ligula and long -acuminated basal lobes; further the outer 

 series of bristles is only l / 12 of the inner one. These structural 

 differences are such as do not occur in one species, hardly 

 in the same group of species. This fact together with the 

 existence of a certain difference in habit (Gleason remarks, 

 1906 b, p. 181: The single specimen examined Wright 

 n. 2786 does not agree in every particular with Lessing's 

 description ), and with the different distribution has induced 

 me to propose this new species.

Not seen. The species comes near to V. angustissima 

 and V. stenophytta, but differs from both in its small - leaves 

 and few-flowered heads.
