Macbride — Certain Borraginaceae 49 
seems to be C. ambigua.”’” However, the specimen represents per- 
fectly C. scoparia, heretofore known only from the plains of west- 
ern Idaho. This extension of range is not surprising as it simulates 
the ranges of many other plants, such as Astragalus Spaldingii 
Gray and Oreocarya spiculifera Piper. 
C. INTERMEDIA (Gray) Greene. C. echinella Greene, Pitt. i. 115 
(1887), should be referred to this species. 
C. ramosa (Lehm.) Greene has an exact synonym in Krynitzkia 
mexicana Brandegee, Zoe v. 182 (1904), which was wrongly com- 
pared with the very different C. pusilla (T. & G.) Greene. 
CRYPTANTHA KELSEYANA Greene, Pitt. ii. 232 (1892). This 
species was described by Greene (I. c.) from one collection, made by 
him August 6, 1889 at Elliston, Montana. He compared it with 
C. Pattersonii. In 1900 Dr. Rydberg (Mem. N. Y. Bot. Gard. i. 
332) referred two other collections to C. Kelseyana and, continuing 
Greene’s comparison, wrote, “‘ three [nutlets] are gray, ovate, acu- 
minate, and sparsely tuberculate, the fourth much smaller, red and 
smooth.’ This statement agrees in substance with Greene’s original 
description but it does not coincide with the facts as they are illus- 
trated in the Montana specimens. Actually the fourth nutlet is 
the largest, the species, in this respect, agreeing perfectly with 
C. crassisepala. I have talked with Dr. Rydberg in regard to this 
discrepancy in the description and he informs me that he is certain 
that Greene’s characterization is incorrect, the error being due, 
probably, either to the immaturity or the poor development of the 
original specimen. I had also reached this conclusion because speci- 
mens invariably have the fourth and smooth nutlet the largest, and 
in the twenty-five years elapsing since the discovery of C. Kelseyana 
no plant answering to the original description has been found. Thus 
interpreted, the species is nearest C. crassisepala. It differs in the 
acute and narrower nutlets, the groove open toward the base and 
there forked but not excavated; and in the sepals which are not 
connivent over the mature fruit but open, the midrib only slightly 
thickened. Since collections representing C. Kelseyana have often 
been confused with C. crassisepala, C. Pattersonii, C. ambigua, or 
C. multicaulis, it seems worth while to cite the following material of 
the New York Botanical Garden (N. Y.) and the Gray Herbarium 
(Gr.).
