DESCRIPTION OF SPECIES— LEGUMINOS^. 301 



Legiiiniiiosites! aracliioidcs, Lesqx. 

 Plate LIX, Figs. Ki, 11. 



CarpolUhes arachioides, Lesqx., Annual Report, 1872, p. 403. 



Capsules or siliques alternate and sessile, on flexuous, tbick, woody pedicels; obovate, rounded to 

 a, short acumen, mostly enlarged on the lower side, bossed under the point as inclosing a round seed, 

 regularly striated with narrow ridges, generally tending in a curve from the borders to the point, 

 obscurely and transversely wrinkled. 



These capsules, or pods, are turned upward in the upper part of the 

 branches, horizontal or pending in the lower part, two and a half centimeters 

 long, one centimeter broad in the middle, flattened by compression, but gen- 

 erally convex or inflated near the point, as from the presence of an inside, 

 large, round seed; narrowed in curving to a very short, broad, petiole. Tlie 

 relation of these racemes of fructification is as yet uncertain; they seem to 

 belong to the Legumiiwscr, especially resembling branches bearing fruits of 

 our Arachis hypogaa, Linn., the Ground-nuts of the South. But they do not 

 bear at the base any trace of remains of the calyx or receptacle, which, in 

 the species of this family, is scarcely absent except perhaps in the fructifi- 

 cations of some Scleroloblum, Cenostigtna^ etc. Fig. 14, left side, has the 

 pedicel attenuated and elongated as part of a broken tendril. 



Habitat. — Evanston, Wyoming; in a block of iron-stone taken out from 

 the mines. No leaves or any other vegetable remains were recognizable 

 but these. The fruits appear of a hard, woody consistence.

Plate XXIX, Figs. 6, 7. 



Leaves small, linear, subfalcate, entire, narrowed to an inequilateral base, pointed or acuminate ; 

 lateral neives close, parallel, camptodrome, separated by short tertiary ones. 



These two fragments of leaves, mixed upon the same specimens with 

 those of Ficus nrenacea, cannot be referable to this species, though they have 

 some characters in common: the thick consistence, the entire borders, and 

 the inequilateral base. The upper part of these leaves is destroyed; they 

 seem to be acuminate and somewhat turned to one side, like leaves of 

 Sapindus. They are also related to this genus by their nervation. The 

 relation is, however, distant, not more definite than with some Leguminosce: 

 Cassia, Podogonium, etc. 



Habitat. — Green River group, Wyoming {Dr. F. V. Hayden).
