PLANTEZ FENDLERIANA, 35 
inch long, deep blue, or perhaps violet, and showy. The stout and thickish pods are 
ascending, an inch and a half in length, one fourth of an inch broad, at first scymetar- 
shaped, but at length turgid and dilated, with a very broad and deep groove on the 
convex side from the strong introflexion of the dorsal suture, while the ventral shows a 
salient ridge and is not at all introflexed. —In some respects this species accords with A. 
humilis, Geyer (Hook. in Lond. Jour. Bot. l. c., —a name which, by the way, is preoc- 
cupied by Bieberstein) ; but that is said to have an ovate fleshy legume, and evidently 
belongs to the same section as A. caryocarpus. May it not be A. pachycarpus? 
149. A. Missourrensis, Nutt. Gen. 2. p. 99. (A. melanocarpus, Richards. ! in 
Frankl. Jour.; Hook.! Fl. Bor.-Am. 1. p. 150. Stony hills, Rio del Norte and at 
Santa Fé; May. — The mature legume is elliptical, compressed, margined, and with 
neither suture manifestly introflexed.* 
1150. A. Hypoerorris, Linn.; Hook. § Arn. Bot. Beech. p- 334. (A. goniatus, 
Nutt.!) Prairie, on the Mora River; August. 
7151. A. sp. Dry, gravelly hills near Santa Fé; May. A dwarf, canescent species, 
of which only a single small specimen was collected, in fruit only; so that it cannot be 
safely described, if new. The legumes are arcuate, nearly an inch long, canescently 
puberulent, deeply grooved at the dorsal suture, and 2-celled. 
+152. A. moxuissimus, Torr. in Ann. Lyc. New York, 2. p. 178, § Fl. N. Am. 1. 
p: 337. Between McNees Creek and Cold Spring; August.— In fruit only ; apparent- 
ly a dwarfish form, with very densely silky-villous foliage. Dr. Gregg gathered it near 
Chihuahua and Lieut. Abert near Bent’s Fort, on the Arkansas. 
7153, A. moxuissimus, Torr. l.c. Ojo de Bernal ; August. — In fruit and flower. 
Leaves, &c., much larger than in the last, and more nearly agreeing with the de- 
scription of this species. The largest leaflets are even an inch and a half in length. 
The stipules cohere for nearly half their length with the base of the petiole. 
+154. Oxyrropis Lamperti, Pursh; Torr. §- Gray, Fl. 1. p. 339:—a variety 
with 7 to 13 leaflets and rather few and scattered flowers; nearly the same as No. 77 of 
Geyer’s Oregon collection. Prairies, Mora River ; August. 
* A. distortus, Torr. & Gray, is found by Dr. S. B. Mead, in Mason county, Illinois. The mature 
legumes are longer than in the original Texan specimens, strongly arcuate rather than abruptly bent, and 
fully three fourths of an inch long, following the curvature, but much smaller than those of A. obcordatus. 
Those of the latter are somewhat laterally compressed, with an acute and salient ventral suture, as described 
- in the Flora of N. America, and the dorsal suture merely sulcate, but little introflexed. In the former, the fully 
ripe legumes of Dr. Mead’s plant are obcompressed, strongly sulcate along both sutures, with the dorsal so 
much introflexed as to become nearly or quite 2-celled.
