Wall. Cat. 8226. Cynoctonum ovalifolium and C. Blumei, Dene. in DC. 
Prodr. viii. 529, 528.  Holostemma leve, Blume Bid. 1055. 
Pznane, Wallich; Maracca, Maingay.—DisrRis. Java. 
Leaves 3-4 by 1j in., coriaceous, pale beneath, nerves spreading; petiole 3-1 in. 
Sepals ovate. Corolla 1 in. diam. ; segments broadly ovate, quite glabrous. Column 
sessile. Follicles 5 in. long, thickly coriaceous, terete, tapering to a narrow but 
stout point, tip recurved, Seeds 4 in., very broad and flat.—‘‘ Produces an excellent 
caoutehoue” (Wallich). Making allowance for the variability of the corona in this 
genus, I am disposed to unite with this the C. formosanum, Maxim. (Diagn. Pl. Nov. 
Asiat. 801), and Cuming’s No. 774 from the Philippines. 
5. C. alatum, Wight § Arn. Contrib. 56; twining, puberulous or 
glabrate, leaves linear ovate or oblong acute base contracted cordate pale 
beneath, umbels shortly peduncled pubescent, corona short cupular plaited 
irregularly crenate, follicles- narrowly 2-winged.. Cynoctonum. alatum, Dene. 
in DC. Prodr. viii. 529; Wight Ic. t..1280. 
NitcHeRrRY Mrs., Gardner, &. TRAvANCORE, at Coimbatore, Wigit. 
Stem slender, sometimes softly pubescent. Leaves 11-23 in., rarely more, very 
variable in breadth, glabrous or puberulous above; basal lobes rounded, sinns open 
or almost closed ; petiole 1-2 in. Umbels 1 in. diam., peduncle and pedicels pubes- 
cent. Calyx lobes ovate. Corolla } in. diam., glabrous, segments oblong-ovate. 
Follicles 2-24 in., dorsally compressed.—Wight’s figure represents the whole plant as 
far too hairy ; he gives Coimbatore:as the only habitat, but. his-specimens are marked 
from the Nilgherries, as are all the others I have seen (Gardner, Hohenacker, 
Schmidt, G. Thomson). In the “ Contributions" he gives Coromandel as the only 
native country, which is unlikely. The plaited. corona has. obseure thickenings on 
some of the folds of the inner face which are rudimentary inner processes. 
6. C. pauciflorum, Br. iw Mem. Wern. Soc. i. 45; twining, nearly 
glabrous, leaves ovate or ovate-lanceolate acuminate; base broadly cordate, lobes 
rounded, umbels shortly peduncled and flowers glabrous, corona much longer 
than the sessile column: 5-lobed with 5 intermediate teeth, follicles terete.

Deccan Pentnsuta; from the Concan southwards to Travancore. CEYLON, very 
common in the Central Province. . 
Stem slender. Leaves 2-2} by 1-1} in., broadest at the base, rather coriaceous ; 
petiole J- I in., glabrous or puberulous; stipular leaves rounded, } in. diam. or less. 
Peduncle shorter than the petiole. Flowers į in. diam. Sepals lanceolate. Corona 
nearly equalling the corolla, campanulate, plieate, large lobes sometimes 2-fid at tho 
tip. Follicles 24 in. long, thinly coriaceous, beak slender. Seeds orbicular, flat, } in. 
diam.—This at first sight resembles C. alatum, but the leaves broad.at the base at 
once distinguish it. The name pauciflorum is not very distinctive. 
7. C. Wallichii, Wight Contrib. 56 ; twining, glabrous, leaves ovate- or 
oblong-lanceolate finely acuminate membranous base deeply cordate with 
rounded decurved or incurved lobes, umbels shortly peduncled and flowers 
glabrous, corona campanulate plicate shortly 5-6-lobed lobes toothed. Wal.

Kuasa and Jynrea Mrs. ; at the foot of the hills, Wallich, &c. 
Stems slender. Leaves 3-5 by 1-2 in., pale beneath, nerves very oblique, basal 
sinus rounded, open or almost closed by the incurved lobes; petiole 1-13 in. 
Peduncles much shorter than the petioles, pedicels slender. Sepals ovate: Corolla
