PENTANDRIA. MONOGYNiA. 155 
lated; peduncles about 3-flowered; flowers 5-petalled; 
fruit scabrous.—Leaves somewhat shining, and remarka- 
ble for their opacity; fruit of the usual brilliant colours; 
theca bursting from the centre—Generally in shady 
moist forests, amongst rocks. The singular habit of this 
plant almost indicates a specific distinction, for the pre- 
sent, however, I cannet consider it as any thing more 
than a permanent variety. : er 
2.* obovatus. Stem prostrate radicant; surculi erect, 
obtusely quadrangular, marked with 4 distinct lines; 
bark and calix inflated, leaves broad obovate, obtuse, 
acttte at the base, subsessile, margin acutely serrulate, 
flat; peduncles 3-flowered; stamina 4 and 5.—A very 
distinct. species, though proximately allied to E. amer7- 
canus. Ops Stem about a foot high, nearly simple, or with 
a few short and opposite branches appearing truncated” 
at their extremities, by the inflation of tiie bark; leaves 
nearly opaque, cuneite-obovate, often dilated so as to ap- _ 
pear nearly as broad as long, margin finely and acutely 
serrulate, serratures and nerves on the upper side mi- — 
nutely hispid (seen through a lens), marginal nerves of 
the petiole decurrent on the stem, forming the sole 
ligatures of attachment bet'vixt the inflated bark and the © 
wood; calix inflated, nearly entire, or crenate, membra-. 
naceous; petals 4 and 5, roundish, green, with a tinge of 
purple; anthers sessile. Ihave not seen the fruit—Has.
