Penstemon 1 species recorded from Colorado (by KWC) were all 
checked or identified by the well known authority on the Scrophu- 
lariaceae, Dr. Francis W. Pennell of the Academy of Natural Sci- 
ences, Philadelphia, Pa. The Colorado Phacelia were likewise 
checked by Prof. Robert Prettyman of Butler University. Phacelia 
sericea and Ph. ramosissima were named by Dr. R. E. Schultes, of 
Harvard University, from dried specimens. Dr. C. D. Michener 
supplied the name Phacelia popei for the record of Pseudomasaris 
texanus, and Dr. J. Bequaert determined the Ph. calif ornica from 
fresh material. 
Of the 1 1 species mentioned below, the first three are all that are 
known from Colorado. The Colorado captures are set off from 
other records in separate paragraphs for ease of reference.
