 — It is doubtful if this species can be maintained as distinct from 

 the preceding, though certainly Hartweg, no. 191 (C. tenuijlora), and 

 Andrieux, no. 156 (G. canescens), specimens cited by Bentham and 

 represented in hb. Gray, are dissimilar, as is indicated in the above key. 

 The flowers seem alike in the dried specimens, though perhaps those of 

 G. canescens spread more widely from the flowering axis. The follow- 

 ing are in hb. Gray, — San Luis Potosi : Parry & Palmer, no. 688,
