parate i'nnn one another, but always stand lower than tin- 

 margin of the corolla. Tlie stigma is two-lobeil. The Iruii 

 is a superior, simple, two lobed capsule, the valves of which 

 being bent inwards, form, with their inner margins, the a{)arl- 

 nient for the numerous seeds. These contain the erect 

 embryon, with its evolved cotyledons, in the middle of the 

 albuminous substance. 



Diag7iosu: 



The most nearly related to this species is the Gcnt'unui, tri- 

 fiora Pall. ; but, in this last species, the linear leaves are alwut 

 two inches long, and pointed. The flowers, though of the 

 same size, are }H'operly without stalks, and are placed by 

 threes on the uppermost axilla'. This species grows in east- 

 ern Siberia. G. algida Pall, has much broader, longer, lan- 

 ceolate, three-nerved leaves. G. asclcpiadca is much larger, 

 more branchy, and has ovate-lanceolate leaves. The other 

 species are still more imlike. 



Geographical Distribution. 

 In Europe this species seems to grow i'rom 45° to 64" 

 N. Lat., for it is not found more southerly than Gretx:e, nor 

 more northerly than Lapland. In North America it seems 

 to be confined to the space between the 40^ and 50" North 

 Lat.
