Nomismta. - LEGUMINOS XE. 237 
with minute glands on the under side, with very minute setaceous partial sti- 
pules at the base of the partial petioles. Racemes axillary, often springing 
from the very young axillary twining shoots. Calyx hairy. Legume sprink- 
led with hairs. ; 
In this genus, as well as in almost all that follow of the Phaseolee, the tenth or 
free stamen is jointed near the base, a character which De Candolle has given to 
Rynchosia alone. Another peculiarity of structure, equally common to this group, 
is that of the style, which, although often compressed in the lower half, is tumid, po- 
lished, and of almost a horny texture for a considerable length below the point: it is 
strange that. De Candolle should have overlooked this, inasmuch as that while de- 
ee Cylista scariosa, where he had noticed it, he supposed it to be the effect of 
accident. 
128. (1) N. nummularia (W. & A.:) petioles longer than the leaves: leaf- 
lets cuneate-obovate, broader than long, retuse ; racemes few-flowered, lax, 
much shorter than the petioles, usually on the young shoots : calyx-segments 
(except the lowest) about half the length of the corolla: legume strongly 
wrinkled with a few parallel transverse slightly branched nerves, with reticu- 
lating connecting veins, terminated by the straight mucro-like base of the 
style, 1-seeded.— Wight ! cat. n. 835.—Glycine nummularia, Linn.! mant.

_ Linneus describes the racemes as slender and longer than the leaves, ow- 
ing to having mistaken the young flower bearing shoots for racemes. 
129. (2) N. capitata (W. & A.:) petioles about the length of the leaves : 
leaflets nearly orbicular with a cuneate base: racemes peduncled, many- 
flowered, longer than the leaves, with a slender leafless and somewhat abor- 
tive young shoot springing from about the middle of the peduncle ; the flori- 
erous portion at first somewhat lax, soon becoming very flexuose twisted 
up and resembling a capitulus: calyx-segments long, subulate, forming a 
short hooked point to the flower-bud during sestivation : vexillum not striped: 
legume marked with numerous close parallel transverse veins, terminated by 
the hooked base of the style, 2-seeded.— Wight ! cat. n. 837.—Glycine ca- 
pitate, Heyne in Roth, nov. sp. p. 946; Spr. syst. 3. p. 197.—Rhynchosia 
capitata, DC. prod. 2. p. 386. à 
ʻe have not seen a specimen named by Heyne or Roth, but, with the ex- 
ception of the legume being stipitate (Roth says sessile), we can perceive no 
essential difference between our plant and Roth’s description. We have, 
owever, specimens from Rottlers herbarium marked by him Hedysarum 
aureum, var., and given him by Heyne. | 
730. (3) N.aurea (W. & A.:) petioles about the length of the leaves: 
leaflets nearly orbicular, cuneate at the base, terminal one often rhomboid 
and slightly acute: racemes peduncled, few-flowered, flexuose, shorter than 
the leaves; not bearing a young shoot on the peduncle : calyx-segments long- 
Subulate, much faleate, forming a long subulate hooked point to the flower- 
bud during wstivation : vexillum broad, elegantly striped longitudinally with 
dark-coloured veins : legumes marked with numerous close parallel me 
veins, terminated by the hooked base of the style, 2-seeded.— Wight / cat.
