A much weaker plant than Z. bona-nox; leaves 2-4 in.; sepals in flower more 
lanceolate, in fruit nearly as of Z. bona-nor ; corolla-tube 1-2 by i in., hairy within; 
peduncle usually greatly thickened under the fruit.— Clearly distinct from Z. bona-noz. 
3. X. grandiflora, Lamk. Ill. i. 407 ; stem usually muricate, leaves 
cordate-ovate acute entire glabrous, peduncles 1-3-flowered short, flowering 
sepals large elliptic, corolla white tube linear, capsule nearly 1 in. diam. 
globose, seeds softly shortly villous margins shaggy. I. longiflora, Br. Prodr.

A large twiner; stem often softly muricate. Leaves 3-6 in. diam., often deeply 
cordate, secondary nerves prominent; petiole 2-5 in. Peduncles usually 1-2 10.5 
flowers 1-3; bracts caducous. Sepals in flower 2-1 in., obtuse or very shortly acute ; 
in fruit enlarged, orbicular, often 1} in. diam., embracing the capsule. Corolla-tube 
24 by 1 in., sometimes much longer, limb 3 in. diam. Capsule obtuse ; peduncles 15 
fruit somewhat thickened.— The length of the peduncle is very variable, almost 0, 1n 
others, as in the Convolvulus asper and in Thwaites's Calonyction comospermum, more 
than 4 in. Brown describes his Z. longiflora as with obtuse sepals, and Bentham $ 
I. longiflora is identical with the Ceylon Z. grandiflora ; but F. Mueller has lately sup- 
plied specimens with much-acuminated sepals, which prove either that the sepals in 
I. grandiflora are eminently variable or that there is another species of Calonyction 
in Australia. 
4. I. trichosperma, Blume Did. 710; stem often muricate, leaves 
ovate-cordate acute glabrous sometimes lobed, peduncles very short 1-fid., 
flowering sepals large elliptic, corolla very large tube much wider than m

Very near 7. grandiflora, but some of the leaves are lobed, and the flower is very 
large; in Parish’s example more than 6 in. long, with the tube 1 in. diam.—The 
Khasian examples are in fruit, and have the leaves very slightly lobed ; some Javan 
specimens have subdigitate leaves.
