As a genus, Roe/la is very nearly related to Campanula. _ 
Ina flower of this fpecies recently expanded, we fee diftinély 
five fhades of colour, which being difpofed in rings, or circles, 
produce a ftriking effe€t; the bottom of the flower is white; — 
of a yellowifh caft, next fucceeds a circle of deep blue, a : 
to black, with afurface highly glazed, the next circle is greyi 
blue, refembling fatin, the next nearly white, and the outermoft 
pale purple. : : | 
The anthere at firft are clofely applied to the furface of — 
the corolla, and refemble fo many {mall ridges; the ftigma, as 
in many other flowers, does not affume its true appearance Ut 
the corolla is on the decay, then it becomes bifid.  —s_ 
This fhrub of low growth, long fince known to the Dutch 
- Botanifts, is a native of the Cape, and was. introduced by 
Mr. Masson in 17743 it flowers in. June, and continues 1m 
bloffom feveral weeks: its foliage does not correfpond wit 
the elegant appearance of its bloffoms; it is a green-houfe 
plant, ufually increafed by cuttings, but not readily, nor 1s the 
plant-fo eafy of culture as many others. eee
