 chartaceous when dry ; ovate or ovate-oblong, acuminate at apex, 

 shortly cordate at base ; both surfaces glabrous and yellow when dry ; 

 margins recurved ; 4 to 6 in. long, 2 to 3 in. broad ; ixiidrib slender but 

 prominent, raised beneath ; main nerves 8 to 10 pairs, the lowest pair 

 nearly at right angles to the midrib, the rest at about 45°, nearly 

 straight, joining towards the margin in a looped intramarginal nerve ; 

 reticulations distant, transverse ; petiole pubescent, "5 to 1 in. long ; 

 Cymes few-flowered ; peduncle 1 to 3 in. long, stout ; bracts small, 

 subulate-acLiminate ; pedicels stout, puberulous, "75 to 1-5 in. long ;

 short ; lobes oblong-lanceolate, acute, 3-nerved with netted reticula- 

 tions, '75 in. long, -3 in. broad ; scales none. Corolla-tVihe 1 in. long, 

 thick, with 5 thick ridges within opposite the anthers, the hollows 

 between the ridges filled with brown stiff retrorse bristles ; lobes

Erect or twining perennials. Leaves opposite. Flowers small, 

 lateral between the bases of the petioles or axillary, in simple or 

 branched cymes of flower-clusters or short racemes, or sometimes in 

 sessile flower-clusters at the nodes of the stem. Calyx 5-partite, 

 5-glandular within. Corolla rotate or rotate-campanulate, deeply 

 5-lobed, the lobes slightly overlapping to the right. Corona of 5 small 

 fleshy tubercular processes, adnate to or radiating from the filament 

 part of the staminal-column and arising from near its base. Staminal- 

 column arising from the base of the corolla ; anthers erect, small, with 

 small membranous appendages ; pollen-masses very minute, erect, sub- 

 erect or horizontal, attached by their middle or near their base to very 

 slender caudicles by wliich they are affixed in pairs to the pollen-
