Type in U.S. National Herbarium, no. 619743, collected at San Rafael, 

 San Luis Potosi, Mexico, November, 1910, by C. A. Purpus and flowered 

 in Washington, July, 1911. 



This is a very remarkable species and quite distinct from all the 

 others which we have had in cultivation. The foliage is of a 

 rather pale green color, quite stiff, almost pungent. The flowers 

 are a lemon yellow, an unusual color in the genus, only one other 

 species being at all like it.
