Stamens unequal, included or exserted ; filaments filiform or dilated at base, 
often hairy, not with processes subconnivent over the ovary; anthers oblong, 
ultimately twisted or straight. Ovary 2-celled, 4-ovuled, rarely 4-celled and 
4ovuled (subgenus Quamoclit), or 3-celled and 6-ovuled (subgenus Pharbitis) ;

Extensively scandent; stems smooth, or not rarely muricate. Leaves 3-8 in., 
glabrate, secondary nervation much less prominent than in Z. glaberrima; petiole 3-6 
m. Peduncles 2-6 in.; bracts caducous. Sepals j in., usually ovate, obtuse, mucro- 
nate, in fruit unaltered or slightly enlarged. Corolla-tube 3 by } in., limb 3-5 in. 
diam., pure white or with plaits greenish, never with at all purple. Anthers shortly 
exserted or subincluded. Capsule narrowed upwards; peduncle at length somewhat 
thickened.—Moon-flower of the English; the flower expands at night, closes to 
wither about one hour after sunrise; see Sir W. Jones in Asiat. Research. iv. 257. 
t does not appear that Linnæus ever saw Z. grandiflora, Roxb., which is perhaps 
Specifically distinguishable from the American Z. bona-nox; there are many speci- 
mens of the typical Z. bona-nox supplied from Asia; but American seeds of this 
were grown in India in Roxburgh's day, if not before. It is consequently now 
MM difficult to decide whether J. bona-nox and I. grandiflora should be regarded as 
istinct.,
