pointed, with short hairs on the upper surface, and the under 

 one downy, from two to eight inches long, and from one to 

 five broad ; those accompanying the ramifications of the in- 

 florescence are very small, more pubescent and coloured, in 

 fact they may be called bractes. Stipules a connecting- ridge 

 only, cxtendhig- through the division of the inflorescense. 

 Panicles axillary, large, downy, generally composed of a 

 few opposite pairs of branches, bearing single, opposite, 

 long-ped uncled involucred umbellets of small white flowers. 

 Bractea no other than the floral leaves above-mentioned. 

 Involucre three-leaved, from five to ten-flowered; leaflets 

 spreading, sessile, oblong, veined, ofien emarginate or refuse, 

 tomentose, much longer than the flowers; those on the inside 

 of the base next to the flowers iiairy like the calyx. Pe- 

 rianth proper, campanulate, five-toothed, both sides clothed 

 with long soft white hair. Corol one-petalled ; tithe cylin-

 viz. the interior one in all the exterior flowers in the same 

 umbeliet, is divided into three short, rounded segments ; the 

 oilier, or exterior one, as long as the tube, and deeply divided 

 into tNvo obovate segments. Filaments four, more than twice 

 the length of the corol, variously contorted; the pair next 

 the long lip shorter. Anthers iwo-\ohei\. GVrwi superior, 

 oblong, two-celled, each cell half divided by two incomplete 

 partitions, which project from the centre of the complete par- 

 tition, containing four seeds attached to the upper end of the 

 angle formed by the partitions. Style as long as the stamina.
