This is a very distinct species of Beloperone. It is related to 
a plant collected by C. G. Pringle at Las Canoas, State of San 
Luis Potosi, Mexico, 1891, No. 3933, and described by B. L. 
Robinson in Proc. Amer. Acad. xxvii. p. 183, 1892 as Beloperone 
fragilis, Rob. Unfortunately this name cannot stand, since the 
same combination had been used long previously by Martius in 
Flor. Bras. ix. p. 140, 1847, to designate a plant, which, from 
the description, is a quite distinct species, from Prov. Bahia, 
Brazil. For the Mexican plant it is proposed that the name 
Beloperone tenera, Turrill, should be substituted for Beloperone 
fragilis, Robinson.
