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

 lanceolate, in fruit nearly as of I. bona-nox ; corolla-tube 1-2 by i 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. CoroUor-tiibe 

 2 J by i 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 ConvoVvulms asper and in Thwaites's Calonyction comospermv/m, more 

 than 4 in. Brown describes hia /. loTigiflora as with obtuse sepals, and Bentham's 

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

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

 /. grandiflora are eminently variable or that there is another species of Calonyction 

 in Australia. 



4. X. trichosperma) Blwme Bijd. 710; stem often muricate, leaves 

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

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

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

 margins shaggy. I. Yomse, Kurz For. Fl. ii. 218. Oalonyction trichospermum,

Very near /. 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, aiid have the leaves very slightly lobed ; some Javan 

 specimens have subdigitate leaves. 



Sttbgentis II. Quamoclit, Chois. in DC. Prodr. ix. 335 (genus). CoroUa 

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

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