deep between them ; veins conspicuously reticulate beneath. Panicles 

 5-8 in. long, lateral, composed of 3-5 distant simple alternate (uni- 

 lateral ?) branches l|-2-J in. long, bearing several sessile umbels of 

 small white flowers scattered along them, minutely and sparsely puberu- 

 lous ; pedicels 1|-1| lin. long, puberulous. Sepals h lin. long, and 

 nearly as broad, broadly elliptic, obtuse, very minutely ciliate. Corolla 

 rotate-campanulate, 1 J lin. in diam., 5-lobed to | the way down ; lobes 

 I lin. long, ovate, acute, glabrous. Coronal-lobes arising from near the 

 base of the staminal-column, erect, free, closely applied to the backs of 

 the anthers, and subinflexed over their tips, flat, oblong, subacute ; no 

 tubercular dilatations at the base of the staminal-column, which is barely 

 I lin. long and is almost destitute of the filamental portion ; anther- 

 wings nearly touching the bottom of the corolla.

Calyx 5-partite. Corolla salver-shaped ; tube inflated at the base ; 

 lobes overlapping to the left and straight or twisted in bud. Corona of 

 5 erect lobes arising from the base of the staminal-column and adnate 

 to it in their lower part, free above, with a narrow or subulate process 

 on their face. Staminal-column arising from the base of the corolla ; 

 anthers oblong, erect, with long erect membranous appendages conni- 

 vent over the apex of the style. Pollen-masses solitary in each anther- 

 cell, erect, attached in pairs to the pollen-carriers by very short 

 caudicles. Style not exceeding the anther-appendages, apical part 

 stout, pentagonal-ovoid. Follicles smooth. Seeds crowned with a tuft 

 of hairs. — Stem twining. Leaves opposite. Flowers of moderate size, 

 numerous, in pedunculate or subsessile umbel-like cymes, subaxillary or 

 lateral between the bases of the petioles.
