This well-known plant, remarkable for its clear rose-coloured flowers, wiih scar- 

 coly a tinge of yeliow, in a genus so very generally of that colour , varies much in 

 the size and tint of their parts. In somc states the flowcrs are large and deep-ce- 

 loured ; in otlicrs ihey are small, pallid, and unattractive. It nalurally iiihabils shady 

 damp places, where ihc tempcralure varies between 68° and 75°.
