ICOSANDllIA— POLYCiYNIA. Cmiarum. 4S3 



which I have from West Greenland, gathered by Mr. W. Jame- 

 son, differs in no other respect from the octopct'nlu, and may be 

 a variety.

Cal. inferior, of 1 leaf, concave, coloured, permanent; limb 

 large, in 10 deep, spreading, acute segments, 5 alternate 

 ones exterior, much the smallest. Pet. 5, less than the 

 smaller segments of the calyx to which they are opposite, 

 attached to its rim, lanceolate, acute. Filam. numerous, 

 from the rim of the calyx, awl-shaped, erect, nearly as 

 long as the corolla. Anth. roundish, incumbent, deci- 

 duous. Germens numerous, small, ovate, smooth, col- 

 lected into a head. Styles straight, simple, short, lateral. 

 Stigmas simple. Seeds numerous, naked, ovate, even, 

 scattered over the surface of a large, dry, spongy, hairy, 

 hemispherical, permanent receptacle. 



Herbaceous, creeping, with pinnate and ternate leaivs, and 

 several Y>amc\edJlo-wers. The genus is allied in character 

 to Fragaria, but totally different in habit. The very 

 unequal calyx, and small lanceolate j5^^a/5, with the spongy 

 permanent receptacle, are good technical characters, strong- 

 ly confirmed by a most distinct habit. It is difficult to 

 conceive upon what principle Fragaria sterilis of Linnaeus 

 could be referred to Comarum -, certainly by no natural 

 or artificial character.
