A native of forests, hedges, &c. it is one of the largest 

 species of the Convolvulacea I know. Flowering" time the 

 wet and cold seasons.

 down. Leaves petioled, broad-cordate, entire ; many large, 

 distinct, opposite nerves running parallel ; the upper side 

 pretty smooth, the under side covered with much soft, white 

 silky hair; from four to twelve inches each way. Petioles 

 shorter than the leaves, tapering, round, at the apex on each 

 side is a large, flat, scabrous, dark-coloured gland. Pedun- 

 cles axillary, like the petioles, but longer, bearing- an erect 

 umbel, of many flowers. Flowers large, of a deep rose-co- 

 lour. Bractes many, large, oval, white, waved, pointed,
