A " tree 20 feet high/' glabrous, apparently varying considerably in 

 the size and shape of the leaves. Ultimate branches more or less four- 

 angled and sharply margined by 2 salient lines decurrent from the 

 base of each petiole : these are sometimes so prominent as to form 

 wings, while on other branches of the same individual they are obso- 

 lete or wanting. Leaves coriaceous in texture, and dull, ovate, or more 

 commonly oblong, varying from 5 inches to nearly a foot in length, 

 and from 2 to 6 inches in width, obtuse, cordate at the base by a small 

 sinus, rather sparsely feather-veined and sparingly reticulated, the 

 veins rather obscurely anastomosing ivithin the margin, opaque, only the 

 thinner states showing pellucid dots : the petiole 3 to 6 lines long. 

 Cymes several-many-flowered, terminal, or sometimes axillary; the 

 common peduncle from one to two inches long, articulated, trichoto- 

 mous, with the rather slender partial peduncles usually again divided, 

 about an inch long ; the ultimate divisions terminated either by soli- 

 tary, or by three sessile, articulated flowers. Tube of the calyx tur- 

 binate, half an inch or less in length ; the short lobes 4, nearly equal, 

 rounded, apparently not enlarged in fruit. Petals probably rose-colour. 

 Stamens and style from an inch to an inch and a half long. Ovary 

 two-celled. Ovules numerous. Fruit not collected.
