gle, no. 4200) : Oaxaca, Cuilapan, alt. 1,840 m., June 27, 1895 (Z. G 

 Smith, no. 778). Originally from Volcan de Jorullo, Michoacan. 

 Briquet bases his species S. trichandra upon Pringle's no. 4200, stating 

 in his description of the calyx that the upper lip is entire. In the speci- 

 mens of this number, as represented in the Gray Herbarium, the upper 

 lip is usually tridentate, thus placing the plant distinctly with S. pru- 

 nelloides.

 puberulent, tubular-campanulate, in anthesis 7 to 8 mm. long, the tube one
