6 in. long. Peduncles 2 to 4 in. long, bearing 3 to 6 large white flowers, 

 usually forming a simple one-sided raceme. Sepals acuminate, i in. long or 

 more. Corollartube near 4 in. long, slender, scarcely enlarged at the top ; the 

 limb opening almost flat, near 5 in. diameter. Stamens and style projecting 

 from the tube. — Oalonyction speciosum, var. vulgare, Ohois. in DC. Prod. ix. 

 345; Wight, Ic. t. 1361. 



On the outskirts of woods, Mance. Widely spread over the tropical regions of tlie Old 

 and the New World, but perhaps introduced into the latter, being much cultivated in gar- 

 dens. The I. muficata referred here hy Choisy as a variety, is a totally different species. 

 It has not the " stamina exserta" of the true bona-nox, whilst the latter has not the " corolla 

 infundihuliformis" of /. murieata, although both of these characters are given as essential to 

 the genus Calonyction. 



6. I. chryseidis, Eer, Sot. Reg. t. 370 ; Chois. in DC. Frod. ix. 383. 

 A slender glabrous twiner. Leaves on long petioles, broadly ovate-cordate or 

 almost hastate, acuminate, 1 to 2 in. long, entire or with 2 broad rounded and 

 sometimes toothed basal lobes. Peduncles as long as the leaves or nearly so, 

 with 2 spreading branches, each bearing 3 to 4 small flowers, with 1 in the 

 fork. Sepals glabrous, coriaceous, oblong or almost ovate, olituse or truncate, 

 nearly equal, about 2 lines long. Corolla yellow, broadly campanulate, about 

 5 lines long. Capsule glabrous, usually marked with 4 raised angles. 



In open places, Hance. Common in tropical Asia. 



7. !• sinensis, Ckois.; DC. Prod. ix. 310. A herbaceous twiner, hoary 

 with rather long stiff hairs, reflexed on the stem, more or less spreading on 

 the leaves and calyxes. Leaves stalked, broadly heart-shaped, entire or ob- 

 scurely S-lo^ed. Peduncles axiEary, 1-flowered, rather shorter than the peti- 

 oles. Plowers about |- in. long. Sepals herbaceous, the outer ones 3 lines 

 long, broadly cordate-lanceolate, the inner ones narrower, lanceolate, and rather 

 shorter.- Corolla narrow-campanulate, not lobed. Stigma, as in the rest of 

 the genus, of 3 rounded lobes. Ovary 3-celled. 



Hongkong, Hance. Only known from S. China. This species has all the characters of 

 Aniseia, which however can scarcely be considered otherwise than as a section of Ifomtsa. 



4. JACQUEMONTIA, Chois. 



Corolla usually broadly campanulate, angular or broadly 5-lobed. Ovaiy 

 3-celled, with 3 ovules in each cell. Style filiform, bifid at the the top, with 

 3 flattened usually oblong stigmatic lobes. Fruit a dry capsule. — Herbs, 

 mostly twining, and sometimes woody at the base. Leaves entire or slightly 

 lobed! Plowers rather small, in axUlaiy pedunculate cymes. 



A small tropical genus, chiefly American, with at least one Asiatic species. It ia inter- 

 mediate, as it were, in the shape of the stigma between I^omcea, and ConvoVmhis. 



1. J. violacea, Ohois. in BC. Prod. ix. 397. A herbaceoias twiner, 

 sometimes nearly glabrous, but usually more or less pubescent. Leaves 

 stalked, heart-shaped, acuminate, entire, 2 to 3 or even' 4 in. long, usually 

 more glabrous than the rest of the plant. Peduncles about as long as the 

 leaves, bearing a dense cyme of blue flowers. Sepals 2| to 3 lines long, the 

 outer ones ovate-cordate, acuminate, and always softly pubescent, sometimes 

 enlarging when in fruit to 5 lines. Corolla broadly campanulate, about J 

 in. long. Stigmatic lobes broaclJy linear, obtuse, recurved. — Convolvulus
