A much weaker plant than I. bona-nox ; leaves 2-4 in. ; sepals in flower more 

 lanceolate, in fruit nearly as of /. bona-nox ; corolla-tube 1-2 by | in., hairy within ; 

 peduncle usually greatly thickened under the fruit. Clearly distinct from /. bona-nox.

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 in. ; 

 flowers 1-3 ; bracts caducous. Sepals in flower |-1 in., obtuse or very shortly acute ; 

 in fruit enlarged, orbicular, often 1-| in. diam., embracing the capsule. Corolla-tube 

 2 by \ in., sometimes much longer, limb 3 in. diam. Capsule obtuse ; peduncles in 

 fruit somewhat" thickened. The length of the peduncle is very variable, almost 0, in 

 others, as in the Convolvulus asper and in Thwaites's Calonyction comospermum, more 

 than 4 in. JBrpwn describes his /. longiflora as with obtuse sepals, and Bentham's 

 /. longiflora is identical with the Ceylon /. grandiflora ; but F. Mueller has lately sup- 

 plied specimens with much-acuminated sepals, which prove either that the sepals in 

 I. grotydiflora are eminently variable or that there is another species of Calonyction 

 in Australia. 



4. Z. trichosperma, Blume Bijd. 710 ; stem often muricate, leaves 

 ovate-cordate acute glabrous sometimes lobed, peduncles very short 1-fld., 

 flowering sepals large elliptic, corolla very large tube much wider than in 

 I. grandiflora, capsule nearly 1 in. diam. subglobose, seeds softly villous 

 margins shaggy. I. Yomee, Kurz For. Fl. ii. 218. Calonyction trichospermurn,

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.

 crimson (in cultivated varieties orange yellow or white), middle-sized, tube 

 narrow long, mouth rather small. Anthers exsert. Ovary 4-celled, 4-ovuled. 

 Capsule 4-celled.
