up; the hard and horny, dark colored edge of this spine extends down to about the middle of the leaf, bearing the 
crowded strong hooked teeth (2-3 lines long) ; below the middle the teeth-bearing margin is herbaceous. The stalk 
is, according to Dr. Parry, 4~10 feet high, 1-2 inches thick below. The flattened branches of the panicle, almost 
horizontal below, longest (2-3 inches) in the middle and nearly erect upwards, divide into not very compact clusters 
of forked pedicels, 2-3 lines in length, the ultimate ones shorter, bearing a profusion of bright yellow flowers. Pris: 
matic ovary a little shorter than the perigone and scarcely contracted at top ; perigone 10-11 lines long, tube only 14-2 
lines long and wide, lobes about 9 lines long and 23 wide; filaments inserted at base of lobes, about twice their length s 
anthers as long as lobes ; capsule 12? inches long, 6-7 lines wide, pointed ; seeds 2} lines in diameter,

Western New Mexico to Northern Arizona, and perhaps eastward to the mountains below El Pas 
apparently not south of the Gila River ; flowers June and July.— The botanical history of this species is (318 (24) ] 
similar to that of most of the larger Agaves, the material for whose definition must be gathered piecem 
and from many different sources. Oct. 19, 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. Cones 
sent flowerbuds from Fort Whipple, which seem to belong to this species. In January, 1868, Dr. C. C. Parry, then 
on a railroad surveying om again found it and allncien seeds, which I distributed in Europe as A. Parryi; the 
young plants, raised from them, are now advertised in nursery catalogues, but no description has yet been published. 
Then Mr. F. Bischoff, of Lieut. Wheeler’s expedition of 1871, brought capsules and seeds home. The first who, 
collecting foliage, flowers, and fruit, enabled me to connect all these scattered fragments, was Dr. J. T. Rothrock, 
Surgeon and Naturalist of Lieut. Wheeler’s Southwestern Expedition of 1874. He met with the plant in “ Rocky 
Cahon” and as far north as Camp Apache in Northeastern 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 our plant, as the margin of the leaves is nearly straight and not “deeply crenate,” ete. 
aves erectish or the outer ones patulous, 10-12 inches long, 3-34 chien: wide, somewhat concave as all Agave 
leaves are, rather abruptly acuminate and terminating in a very robust spine, 1 inch long, flattened above, with two 
sharp lateral angles and a slight ridge in the middle ; from this spine a horny, brown margin runs down the leaf-edges 
for 1 inch or more and to the uppermost teeth. Teeth 6-12 lines apart, comparatively small, only about 13 lines long, 
straight, or slightly curved up on upper, and smaller and curved back on lower part of leaf. Scape 8-12 feet high, 
1-2 inches thic numerous large (2 inches wide at base, and twice as long, smaller upwards), triangular, 
closely adpressed bracts, herbaceous, with scarious brown margins and sharp points. Panicle itself, in 
well-developed plants, about 3 feet long, and 1 foot in diameter, the stouter branches considerably flattened, [313 (25)] 
? inch wide, 6 inches long ; ultimate pedicels usually 2-3 lines long. Flowers over 2 inches, the perigone 
12-14 lines long, tube 4-4} lines long and wide, lobe 9-9} lines long and 2 wide ; stamens inserted at the base of the 
lobes, the inferior a little lower than the exterior ones; filaments 1} inches, anthers 10 lines long ; style often at last 
longer than stamens. Capsule wider in proportion to its length than in any other of our species belonging to this 
section, about 13 inches long and half as wide ; seeds 4 lines wide, with flat, punctulate, strongly marked reticulation,

San Domingo, Parry & Wright, U. S. Expl. Exp., Feb. 1871, in flower. —The unusual color of the flower and 
the native country a the plant make it almost certain that this is Descourtil’s plant, and I adopt his, the oldest name, 
even if Grisebach’s (Flor. West. Ind. p. 582) suggestion should prove true, that it might be identical with A. soboli- 
fera, Salm, hort. 1834 (A. vivipara, Lam., non Linn.). This plant is also reported to come from San Do omingo and
