Distinguished from A. cephalantha by the form of the leaf and colour of the 

 ower, and also by the somewhat larger obscurely veined bracts and still coarser 

 indumentum. 



20. A. delamereana, Rendle in Journ. Bot. 1901, 60. Shrubby. 

 Stem robust, densely clothed as are the peduncles and petioles with 

 subferruginous stellate tomentum. Leaves broadly ovate or sub- 

 orbicular, 2|— 4 in. long and broad, apex subobtuse, inconspicuously 

 mucronate, base shallowly cordate, undulate in the margin, stellate- 

 pubescent on both surfaces, more densely beneath ; veins prominent 

 beneath and stellately tomentose ; petiole |-1 in. long. Flowers in 

 dense many-flowered heads ; peduncles stout, 1-2 in. long, 1 lin. thick, 

 free from the subtending leaf ; pedicels under 2-1- lin. long ; bracts 

 small, oblong-acuminate, caducous. Sepals unequal, about 5 lin. long ; 

 2 outer ovate, subacute, stellate-pubescent, hiding the lanceolate inner 

 ones. Corolla funnel-shaped, nearly 2 in. long, apparently a very pale 

 purple. Filaments 4-6 lin. long. Ovary glabrous.

21. Ipomoea dendroidea, Choisy in Mem. Soc. Phys. Geneve, viii. 

 55. Stem shrubby, terete, branched, clothed like the leaves with 

 yellowish-black stellate pubescence. Leaves linear-lanceolate, entire, 

 obtuse, subsessile, 1-2 in. long, 3-6 lin. broad. Peduncle 1-fiowerecl, 

 very short. Calyx-segments ovate-oblong, obtuse, unequal, 3 lin. long, 

 outer with a median line of stellate hairs, inner glabrous. Corolla 

 funnel-shaped, yellow, scarcely 1 in. long; tube very narrow, glabrous. 

 Capsule glabrous, 4-valved. Seeds like a grain of wheat, clothed with 

 simple red-brown hairs. — DC. Prodr. ix. 356.

 Perhaps this is a species of Astrochlcena. 



25. QUAMOCLIT, Tournef. ex Moench, Metb. 453. 



Sepals herbaceous, subequal, small, glabrous, obtuse, often mucronu- 

 late or appendaged below the tip. Corolla in African specimens 

 hypocrateviform, scarlet, glabrous ; limb small. Stamens and style 

 exserted. Ovary glabrous, 4-celled, 4-ovuled. Pollen and stigma of 

 Ipomma. Capsule 4-celled, 4-seeded. Seeds generally glabrous, dark. — 

 Annual climbing herbs, usually glabrous. Leaves entire, lobed or 

 pinnate. Flowers rather small, in lax cymes. — Ipomoea, Benth. et
