Dry hills, Northern States, especially New Jersey ! to Louisiana! Arkansas
! and Texas ! Aug.-Sept.—This species appears to assume a variety
of forms, and is not easily defined. It is, as it were, intermediate between
L. violacea and L. hirta; some forms approaching the former so as to be
essentially distinguished only by the many-flowered peduncles, more hairy
legumes, and few apetalous flowers ; while others differ from L . hirta chiefly
in the purple flowers, smaller leaflets, ■ rather shorter calyx, longer and less
villous and more pointed legumes, &c. and connect this section with the
succeeding.
§ 2. Flowers all fertile and perfect, in dense or 'capitate spikes : corolla about
the length of the calyx, white or ochrpleucous, with a purple spot on the

5. L. hirta (E ll.): stem erect, branching above, villous or tomentose;
leaflets roundish-oval or somewhat obovate, emarginate, pubescent or silky,
mostly longer than the petiole ; spikes oblong or cylindrical; the peduncles
at length much longer than the leaves ; calyx very hairy ; the segments
linear-lanceolate, acuminate, somewhat 3-nerved, scarcely exceeding the oval
villous legume.—Ell.' sk. 2. p. 207 ; Torr.! comp end. p. 267. L. poly-

<5. Louisiana, Drummond. Arkansas, Nuttall! Dr. Pitcher! Aug.-
Sept.—Stem 2-4 feet high, wholly herbaceous. Calyx-segments lanceolate-
subulate. Corolla white vexillum oblong, scarcely spreading, with a purple
spot near the base : wings narrow, scarcely auricled at the base.__This
plant has been generally supposed to be the Hedysarum fratescens of Linnaeus
; but that species was founded on a plant of Clayton’s (H. fol. ternatis ;
foliohs subovatis, See. Gronov. ! Virg.), which, as our most esteemed friend
Jjr. x5oott first observed, is Linnaeus’s own H. violaceum, while the synonym
of Gronovius, adduced under the latter species, belongs to Psoralea melilo-
toides . But the reference to Mill. diet, in the second edition of the Species
Plantarum doubtless relates to the present species.
Arachis bypogasa (the Pea.nut) was sent in the late Mr. Drummond’s collection,
from Covington, Louisiana; but the specimens were doubtless cultivated.
Psoralea, Linn, should doubtless be referred to the tribe Hedysare®: as Mr.
Dentham has suggested.
