petioled. Calyx very small for the flower. Corolla 21-3 in., widely tubular-funnel- 
shaped, nearly glabrous without, purple. Stamens included; anthers not twisted. 
Ovary 2-celled; stigmas 2, sessile, globose.— Fruit not seen, hence this may be an 
Ipomea; but the large long-petioled leaves and large wide-tubed corollas indicate 
rather Lettsomia. This resembles L. elliptica, Wight, which has smaller flowers, more 
numerous in the corymbs.

Scandent; stems sparsely softly hairy. Leaves 4 by 3 in, somewhat deeply 
cordate ; petiole 2-3 in. Peduncles 2-44 in.; bracts deciduous before the flowers 
expand ; pedicels 1-3 in. Sepals l-lin. Corolla 13-2 in., widely tubular-funnel- 
shaped, softly silky without on the plaits, at least when young, rose-purple. Ovary 
elled ; stigmas 2, sessile, globose. Fruit not seen.—From the habit and few- 
flowered peduncles, this has been supposed a Rivea ; but the ovary is 2-celled. The 
var. lanata, Choisy, is founded on Convolvulus glandulosus, Ham. in Wall. Cat. 2252, 
collected in Lower Assam. This plant is not now in Wallich’s herbarium, but from 
the deseription it may have been Argyreia Roxburghii, Choisy.
