OCTANDRIA— MONOGYNIA. Chlora. 217 



leafy throughout the winter. Stems simple, numerous, leafy, de- 

 cumbent, hardly a span long, roundish, with 4 angles j the 

 flowering extremities ascending ; the base when luxuriant throw- 

 ing out a few weak leafy branches. Leaves opposite, on short 

 stalks, more resembling E. roseum than any other species, but 

 more pointed and of a deeper green. Fl. in leafy clusters j the 

 Jloral leaves often alternate. Petals broadly heart-shaped, rose- 

 coloured, veiny, full as large as those of E. palustre. Germen 

 and base of the calyx clothed, more or less, with fine, close, hoary, 

 recurved hairs. Capsule long and slender, generally smooth. 

 There can be no doubt of the wide difference between this and all 

 varieties of the following, with which it was long confounded.
