356 SYSTEMATIC BOTANY 



twisted in bud, and generally funnel-shaped. The 

 stamens are five, the ovary superior two-celled, with 

 two ovules in each cell. The fruit is in some genera 

 fleshy, but in most a capsule which opens irregularly, 

 or is circumciss. The cotyledons are usually long and 

 rolled up in the seed. 



The genera differ in the fruit, whether fleshy or dry, 

 in the ovary being one or two-celled, in the shape of 

 the stigmas, and the hairiness of the filaments. 



Of the other species commonly grown in gardens, 

 or otherwise known: 



I. CARNEA, Jacq. is a garden shrub with somewhat 

 leafless stems and large pale mauve flowers, which 

 are usually very numerous at the beginning of the hot 

 weather. 



I. HEDERACEA, Jacq. has bright blue or purple flow- 

 ers, and palmately three-lobed leaves. 



I. BONA-NOX, L., the Moon-flower, has a corolla of 

 a rather different shape having a narrow tube with 

 large almost flat limb. It opens at night, and emits 

 a strong scent, which attracts moths, for whose long 

 tongues this tube appears to be an adaptation (p. 235). 



I. QU^EMOCLIT, L. is a small annual of a few weeks' 

 duration, with dark green, very much divided (pin- 

 natisect) leaves. The corolla has a tube, an inch or 

 so long, of a brilliant red colour, with expanded limb. 



I. BILOBA, Forst., (l. PES-CAPR^E, Roth.), is a creeper 

 on sandy seashores. The leaves are two-lobed ; the 

 creeping stems and branches are usually covered by 

 the drifting sand, but the leaf-stalks lengthen to keep 

 the blades above it (p. 112). It is very common 

 on sea beaches in the Tropics, where it grows with
