ICOSANDRIA— POLYGYNIA. 



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

 son, differs in no other respect from the octopet'ala, 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. Pef. 5, less than the 

 smaller segments of the calyx to which they are opposite, 

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

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

 long as the corolla. Ant/i. roundish, incumbent, deci- 

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

 lected into a head. Sfi/les straight, simple, short, lateral. 

 Stigmas simple. Scec/s numerous, nakecl, ovate, even, 

 scattered over the surface of a large, dry, spongy, hair^-, 

 hemispherical, permanent receptacle. 



Herbaceous, creeping, with pinnate and ternate leaves, and 

 several pan\c\ed JloxnTrs. The genus is allied in character 

 to Fraga)-ia, but totally different in habit. The very 

 unequal catijx, and small lanceolate p^/^/.s, 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 Linnajus 

 could be referred to Cnmannn ,■ certainly by no natural 

 or artificial character.
