CYANOSPERMUM. LEGUMINOS JE. 259 
3-toothed at the apex : calyx somewhat thin and membranaceous ; upper seg- 
ment narrow-lanceolate, longer and narrower than the lateral ones: both 
spurs on the ale linear-subulate: legume 1-2-seeded.— Wight! cat. n. 878

LVI. CYLISTA. Ait. 
Calyx ebracteolate, scariose (or membranaceous ?), deeply 4-cleft ; upper 
segment 2-lobed (or bifid ?) ; lateral ones much smaller; lowest very large. 
Corolla much smaller than the calyx, papilionaceous, persistent : vexillum 
with two callosities at its base: keel slightly faleate, its petals distinct from 
the base to the curve: ale linear-oblong, spurred at the base on the upper 
margin, slightly gibbous on the lower. Stamens diadelphous (9 and 1). 
Ovary oblong, with 1 (or 2?) ovule. Lower part of the style slender, hairy, 
recurved along the lower suture of the ovary ; upper part tumid, glabrous, 
ascending and parallel to the lower part. Legume obliquely oval, enclosed 
within the calyx, 1- (or 2?-) seeded. Seed compressed, reniform, with a 
small ‘hilum and inconspicuous carunculus.—Perennial twining shrubby, pu- 
bescent or villous plants. Leaves pinnately trifoliolate: leaflets oblong or 
ovate, acuminated. Partial stipules very minute or wanting. Racemes axil- 
lary. Bracteas very caducous. 
We are uncertain whether or not C. villosa, Ait., belongs to this genus, as we have 
never had an opportunity of examining its flowers ; it probably has the callosities on 
the vexillum, Andrews having at one time placed it in Dolichos. 
796. (1) C. seariosa (Ait.:) racemes shortly peduncled, about as long or 
a little longer than the leaves: calyx twice as long as the corolla ; tube short, 
campanulate ; segments very large, thin and scariose, reticulated with co- 
loured veins ; upper one broad, 2-lobed, the lobes ovate-obtuse; lower the 
largest, eymbiform ; lateral ones much smaller than the others, cordate- 
ovate.— Ait. hort. Kew. 3. p. 512; DC. prod. 2. p. 410; Spr. syst. 3. p. 194 ;

We have uniformly found the ovule and seed solitary ; Roxburgh likewise 
Appears to have found them so: but most authors describe the legume as 
Somewhat 2-seeded ; perhaps their characters have been derived from the 
Pent in a state of cultivation, and ought therefore to be regarded as of little 
value. 
LVII. CYANOSPERMUM. W. & A.—Cylista, Roxb. (partly). 
Calyx herbaceous, ebracteolate, bilabiate, divided almost to the base 3 lips 
about equal : upper cuneate, bifid ; lower tripartite ; segments oblong-linear, 
the middle one scarcely longer than the others. Corolla slightly shorter than 
the calyx, persistent, rigidly scariose, papilionaceous: vexillum obcordate, 
spreading, without callosities: keel slightly faleate, obtuse; the petals dis- 
tinet except for a small space at the curve. Ovary 2-ovuled. Lower part of 
the style ascending, slender, hairy ; upper part glabrous. Stigma slightly ca- 
Pitate. Legume 2- (or, from the abortion of the lower one, 1-) seeded, 
Scarcely so long as the calyx, constricted all round between the seeds and as 
if formed of two spherical lobes. Seeds globose, with a small hilum without 
à carunculus.—Twining suffrutescent tomentose plants. Leaves pinnately 
trifoliolate ; leaflets broadly ovate, acute or acuminated. Stipules lanceo-
