Lettsomia.] ci. cONTOLTULACEiE. (C. B. Clarke.) 195 



petioled. Cal^x very small for the flower. Corolla 2J-3 in., widely tubular-funnel- 

 shaped, nearly glabrous without, purple. Stamens included; anthers not twisted. 

 Orary 2-eelled; stigmas 2, sessile, globose. — Frmtr^ot seen, hence this maybe an 

 IpomcBa ; 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.

 Tiairy beneath, peduncles long 1-5-fld., bracts caducous, sepals vsddely elliptic 

 obtuse sparsely softly hairy. Convolvulus rubens, Wall. Cat. 1421. Ipomsea

Scandent; stems sparsely softly hairy. Leaves 4 by 3 in., somewhat deeply 

 cordate ; petiole 2-3 in. Feckmcles 2-4^ in. ; bracts deciduous before the flowers 

 expand ; pedicels ^-f in. Sepals ^— J in. Corolla ] ^-2 in., widely tubular-funnel- 

 shaped, softly silky without on the plaits, at least when young, rose-purple. Ovary 

 2-ceIled; stigmas 2, sessile, globose. Fruit not seen. — Prom the habit and few- 

 flowered peduncles, this has been supposed a Bivea ; 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' description it may have been Argyreia Soxburghii, Choisy.

 above ; petiole ^-| in. Peduncle 0-J in. ; bracts numerous, scarcely i in. broad, 

 iulvous-hirsute. Sepals J in., elliptic-lanceolate, in fruit ovate. Corolla Ij in.,
