of the Gila River; fl.June and July.— The botanical history 
of this species is similar to that of most of the larger Agaves, 
the material for whose definition must be gathered pieceiheal an$. 
from many different sources. Oct. i#, 1846, a fruiting specimen 
was collected near the “Copper Mines” by Lieut. Emory, in the 
California expedition (see p. 310), 1. c. p. 59, now preserved In 
the Torrey herbarium and mentioned in the Mex. Bound. Botany 
as a short and broad-leaved form of A. Americana. In 1865 
Dr. E. Coues sent flowerbuds from Fort Whipple, which seem to 
belong to this species. In January, 1868, Dr. C. C. Parry, then 
on a railroad surveying expedition, again found it and collected!!! 12.

plants, raised from them, are now advertised in nursery cata¬ 
logues, but no description has yet been published. Then Mr. F 
Bischoff, of Lieut. Wheeler’s expedition of 1871, brought capsule^! 
and seeds home. The first who, collecting foliage, flowers, and 
fruit, enabled me to connect all these scattered fragments, was rum) ovario 
Dr. J. T. Rothrock, Surgeon and Naturalist of Lieut. Wheelerfs 
Southwestern Expedition of 1874. He met with the plant in 
“Rocky Canon” and as far north as Camp Apache in Northeast-' 
ern Arizona. Why Koch and Jacobi should have referred the 
short notes of Torrey to a plant which they found in cultivation 
in Europe, is unknown to me ; Jacobi's description does in nowise 
agree with pur plant, as the margin of the leaves is nearly straight 
and not “deeply crenate,” etc. 
Leaves erectish or the outer ones patulous, 10-12 inches long, 
3 - 3 ^ inches wide, somewhat concave as all Agave leaves are, ra¬
