430 ICOSANDRIA— POLYGYNIA. Geum. 



this species, smooth and naked, soon falls off with the stigma. I 

 do not find the economy of these organs clearly explained by 

 authors. The seeds, according to Gsertner, have only a simple 

 pellicle, or membrane, within their hairy outermost coat, and the 

 latter therefore cannot come under the denomination of any sort 

 of seed-vessel. 

 The flowers of Ehrhart's G. intermedium are not, either in his spe- 

 cimens or mine, much larger than the common urhanum, but 

 they are of a tawny hue, and rather drooping. The divisions of 

 the leaves vary in both. I have suspected this G. intermedium 

 might be a variety of rivale, caused by the pollen of urhanum j 

 but, on account of its general aspect, have removed it hither. 

 The styles seem to agree best with G. rivale. I have not seen 

 the ripe seeds, which it would be desirable to examine. I follow 

 the opinion of Ehrhart in the synonyms attached to this variety, 

 not having been able to verify them.
