I liave not seen this pla-nt and refer it to the ii^enus Anisopus uitli some hesita- 

 tion ; but the situation of the outer corona at tlio mouth of tlie eoroll<.i-tuhe seems li» 

 indicate an alliiince witli that geiuis, and it may even he the same as A. Mannii,

 Marsdenia hicoronata, K. Sdium. , does not ajrrce with the descrijttion, nnd is A.

Calyx 5-partite. Corolla-tube campanulate ; lobes ">, erect, spreading 

 or rotate-campanulate, overlapping to the left and straight or .slightly 

 twisted in bud. Corona of 5 fleshy lobes arising from the staminal 

 column, with their basal part adnate to it, but often with free margins, 

 or projecting like tubercles, which are sometimes confluent at the base, 

 producing more or less the appearance of an outer corona, their apical 

 part free, erect or somewhat connivent, applied to the backs of the 

 anthers. Staminal-column arising from or near the base of the corolla ; 

 anthers erect, with the cells usually more or less concealed under the 

 margin of the dilated part of the style ; appendages membranous, fiee 

 or connate, more or less incumbent on the top of the style. Pollen- 

 masses erect, solitary in each anther-cell, attached in pairsto the pollen- 

 carriers by short or elongated, moderately stout caudicles. Style 

 depressed, convex, conical, or produced into a long beak at the apex. 

 Follicles with a thick pericarp, smooth, sometimes win<;ed. Seeds 

 crowned with a tuft of hairs. — Climbing or erect perennials. Leaves 

 opposite. Flowers small or of moderate size, arranged in umbel-like 

 cymes, or in small sessile umbels or clusters scattered along the 

 branches of the cymes or panicles, which ai-e lateral at the nodes or 

 axillary. — Dregea, E. Meyer; Benth. et Hook. f. Gen. PI. ii. 775.

I cnnnot find any clmracter wliatever to separate Dreqea from Marsdenia. The 

 foronal-lobes of Dret^ea are erect in tbe specits on whicli Meyer fonndcd his jjcnu^. 

 as well as in all the others tliat I have examined, hut in one or two they are very 

 much laterally compressed, and as viewed from above present a stellate appearance.
