408 BOTANICAL GAZETTE [NOVEMBER 
Dr. C. A. WEATHERBY, who after careful comparison with the 
types left by Dr. Gray wrote as follows: 
The type of P. acutifolius Gray is a plant collected by WRIGHT in western 
Texas in Sept. 1849... .. Your plant is evidently near it, differing in its much 
longer petiolules of the central leaflet and in its broader leaflets. The plants 
[referring to the photographs] with narrow leaflets are P. acutifolius var. 
tenuifolius Gray [fig. 6]. There is also a second variety mentioned by Dr. 
RAY in the Plantae Wrightianae [2:33] without name, which has leaflets 
larger and broader than in your plant and of which I will send a tracing. 

Fic. 7.—The tepary (Phaseolus acutifolius var. latifolius, n. vat.) 
The tracing of the type specimen of P. acutifolius Gray furnished 
by Dr. Ropinson was found on comparison to be intermediate in 
form between P. acutifolius var. tenuifolius on the one extreme and 
the tepary on the other. The tracing of Dr. Gray’s larger, broader- 
leaved, unnamed variety of P. acutifolius, although larger than 
the small specimen of the tepary which I submitted to Dr. RoBIN- 
SON, was identical with the tepary as grown upon the testing grounds 
at this station. In fact, this tracing might have been drawn from 
any one of a number of herbarium specimens of the tepary which 
I have made during the present season (figs. 7-9). 
Careful measurements of the leaves of the specimen of P. 
acutifolius found in the National Herbarium were furnished by
