LEGUMINOSEÆ
Sophora (Pseudosophora, De C.) sericea, Nutt. Torr. in Ann. Lyc. Novebor, p. 174, n. 65. Our specimen is entirely covered with white appressed hairs, which cover also the upper side of the leaves; the flowers are white; the calyx is gibbous below, and quinquefid; the upper teeth are broader and rather shorter. Of the 10 stamina every 2-3 are united at the bottom by the thick filaments; the two upper ones are more slender, and quite free. The ovary is covered with silky hairs; the claw of the standard is very stiff; the keel runs into a narrow point, as in Oxytropis.
Thermopsis rhombifolia, De C. (Thermea rhombifolia, Nutt.; Cytisus rhombifolius, Pursh.)
Petalostemum violaceum, Mich., var. foliis plerisque ternatis.
Petalostemum virgatum, nob. P. spicis cylindricis compactis, bracteis scariosis obovatis cuspidulatis calyce paulo brevioribus, calycibus glabris sulcatis dentibus ciliatis, foliolis subtrijugis lanceolato-oblongis glabris, caule ramoso virgato ramis monostachyis.
Intermediate, between the two divisions of this genus, the proper Petalantheræ and Kuhnisteræ. The perfectly spiked inflorescence connects it with the former; the nature of the bracteæ and the ciliæ of the shorter teeth join it to the latter. From the two white flowering Petalostemones P. candidum and macrostachyum, it is sufficiently distinguished by the two short bracteæ, quite hidden under the flowers; it cannot be more closely connected with Petalostemum corymbosum, because of the spiked inflorescence.
Psoralea incana, Nutt. (Ps. argophylla, Pursh.) Folia in nostra quinata, summa ternata.
Psoralea tenuiflora, Pursh? Foliola ternata, oblongo-lanceolata, mucronata. Legumen ovatum, in rostrum attenuatum, glandulosoexasperatum, calyce longius. Flores cœrulei. An nov. sp.? Quite the form of an amorpha, but the flowers appear like those of glycyrrhiza; unfortunately it cannot be accurately examined.
Amorpha nana, Nutt. De C. (A. microphylla, Pursh.) Calyx glaber dentibus ciliatis.—Oxytropis Lamberti, Pursh.
Astragalus Missurensis, Nutt. An cum A. Hypoglotti conjungendus?—Astragalus racemosus, Pursh. Var. foliolis foliorum inferiorum ovalibus.
Astragalus gracilis, Nutt. Torr. l. c. p. 179. This is indisputably the Dalea parviflora, Pursh, but whether really his Astragalus tenellus, I doubt.—Astragalus Carolinianus, L.
Lathyrus polymorphus, Nutt. De C. Torr. in Ann. Lyc. Novebor. II. p. 180, n. 99. (Lathyrus decaphyllus et Vicia stipulacea, Pursh.)—Vicia Americana, L.
Vicia Americana β angustifolia; foliolis oblongo-linearibus mucronatis pubescentibus. An distincta species?
