greenish ; segments oblong-lanceolate, longer than the corona, which is membranous

Stem robust, glabrous or sparingly hairy. Leaves 3-5 in., very variable in 
breadth, basal lobes small rounded, sinus narrow, midrib broad, nerves very slender 
spreading ; petiole 3-1 in. Peduncles shorter than the petioles. Flowers 4 in. diam., 
quite glabrous Corona follicles and seeds as in C. alatum.—Very closely allied to 
C. alatum, but quite distinct in the much larger size and glabrous habit. 
tt Peduneles of cyme long, slender. 
9. C. corymbosum, Wight Contrib. 6; quite glabrous, leaves ovate- 
or orbicular-cordate cuspidate or acuminate membranous glaucous beneath, 
basal lobes rounded decurved or incurved, peduncles long equalling the long 
petioles, corona campanulate plicate with longitudinal thickenings within, mouth 
irregularly crenate, anthers sessile, follicles large clothed densely with long 
fleshy spines, Wall. Cat. 8222, 8231, F. Cynoctonum corymbosum, Dene. in

Stem rather stout. Leaves 2-6 by 1-3 in., membranous, white beneath ; petiole 
1}-3 in.  Peduncle slender; flowers racemose or corymbose, j-j in. diam. quite 
glabrcus. Sepals ovate, obtuse. Corolla-segments obtuse. Corona large, much 
longer than the short column, with internal thiekenings as in C. alatwm. Seeds 
4 in. long, orbicular-ovoid, with a wrinkled nucleus surrounded by a very broad 
wing deeply crenate at the lower end.—The large lanceolate almost fleshy follicles, 
4-5 by 1-1} in. diam., densely clothed with soft reversed hooked spines 4-} in. long, 
are quite peculiar, and recall those of Demia. It is remarkable that this species, 
though collected both in the Nicobar Islands and Penang, should never have been 
found in Burma or the Malay Peninsula. 
10. C. deltoideum, Hook. f.; twining, glabrous or nearly so, leaves 
deltoid-cordate acuminate membranous, peduncles slender, flowers small 
umbelled glabrous, corona 10-lobed to the middle, 5 lobes large ovate obtuse, 
5 intermediate very small rounded.

Stem slender. Leaves 2-3 in. long and nearly as broad, pale beneath, basal lobes 
large rounded, sinus broad; petiole 1-14 in. Umbels many-fld.; peduncle longer 
than the petiole, and pedicels hairy. Sepals ovate, glabrous. Corona concealing the 
sessile column, the large lobes elliptic and thickened, smaller membranous.
