ATYLOSIA. LEGUMINOS X. RST 
ginary ; at least they neither bear any relation to the colour of the flowers, 
nor are constant on the same individual. Sprengel has added two other spe- 
cies, but they belong to different genera. 
LIV. ATYLOSIA, W. & A.—Collæa, DC. (partly). 
Calyx ebracteolate, campanulate, deeply bilabiate ; upper lip very shortly 
split at the apex ; lower 3-partite, the middle segment longer than the lateral 
ones, and slightly longer than the upper lip. Corolla papilionaceous, at 
length scariose, persistent: vexillum broad, recurved, a little longer than the 
other petals, without callosities: keel slightly faleate, obtuse. Stamens dia- 
delphous (9 and 1), alternately a little shorter: anthers uniform. Ovary 
about 4-ovuled. Lower part of the style slender, hairy ; upper part glabrous. 
Stigma slightly capitate: Legume oblong-linear, compressed, about 4-seeded, 
slightly constricted externally, and with cellular partitions internally between 
the seeds. Seeds roundish: hilum oval, with a large fleshy carunculus.— 
Erect or diffuse shrubby plants. Branches villous or tomentose. Leaves 
palmately trifoliolate : leaflets 3-nerved at the base. Partial stipules wanting. 
Peduncles axillary, or forming a kind of raceme along the young almost leaf- 
less terminal shoots, generally 2-flowered, rarely wanting and with two axil- 
lary pedicels. Legume villous or tomentose. 
This genus we have been induced to separate from the last principally on account 
of the persistent corolla, the absence of callosities on the vexillum, the large carun- 
culus to the seed as in Cantharospermum, and the foliage. 
790. (1) A. Candollii (W. & A.:) erect: branches straight, twiggy ; young 
parts villous with fulvous hairs: leaflets oval; upper side even, pubescent ; 
under reticulated, shortly tomentose, villous on the nerves and margin: sti- 
pules lanceolate, acuminated, spreading: peduncles 2-flowered, longish: 
calyx villous ; segments lanceolate-acuminated, curved upwards, lowest one 
about half the length of the keel: spurs of the vexillum introflexed, slightly 
callous: legumes villous.— Wight ! cat. n. 763.—Collxa trinervia, DC. mem. 
leg. p. 247. t. 41; prod. 2. p. 240.—Odonia trinervia, Spr. syst. suppl. p.219.— 
Rhynchosia Wightiana, Grah.! in Wall.! L. n. 5500. Neelgherries.. 
In our specimens from the Neelgherries, the leaflets are obtuse as in De 
Candolle's figure and description ; but others from Ceylon are more robust, 
with the habit and leaves of the next species: the two, however, are, we 
think, distinct. 
791. (2) A. major (W. & A.:) erect: branches straight, twiggy ; young 
parts villous with fulvous hairs: leaflets oval, slightly acute at both ends; 
upper side even, pubescent ; under reticulated, shortly tomentose, villous on 
the nerves and margin: stipules lanceolate, subulate, spreading: peduncles 
2-flowered, longish: calyx villous; segments subulate, curved falcately a 
wards, lowest one as long as the keel: spurs of the vexillum introflexed an 
slightly callous: legumes villous.— Wight ! cat. n. 762.—Collea trinervia, 
Wall.! L. n. 5571 (not DC.)——Neelgherries. i 
y allied to the former, but larger, and with larger flowers and a longer 
calyx. 
792. (3) A. rugosa (W. & A.:) branches slender, elongated, me 
tose: leaflets obovate, densely velvetty on both sides ; upper dy ; un £ 
Strongly reticulated, whitish : stipules oval, adpressed : peduncles E owered, 
occasionally very short: calyx shortly tomentose ; segments lanceo ate, t 
minated, slightly curved upwards, lowest shorter than the corolla: vexillum 
slightly thickened along the elaw and base of the limb: legume velvetty.—
