inverted heart-shape^ shorter than the two filaments. The 

 filaments stand before the calyx leaves, and alternate like 

 them with the petals, (196.) The stigmata are two. The 

 aestivation is valvular. 



The capsule consists of two loculi, opens from Mow, and 

 contains in each loculus a seed, which, without any albumi- 

 nous matter, contains a completely unfolded embryon, with 

 two erect, thickish cotyledons, and a radicle scarcely distin^ 

 guishable. 



A subspecies of this plant is produced in mountain forests, 

 and especially in North America, with a smoother stem, with 

 the leaf-stalks completely linear and smooth, and with leaves 

 more softly ciliated. This is the Circcea intermedia^ Ehrh.

The Circaa alpina, again, is essentially distinguished 

 by a smooth, branchy stem, which is never longer than a 

 small span, and by small cordate leaves. There is also a 

 small bractea vmder every flower, which is wanting in our 

 species. 



Geographical Distribution. 



The Circaea lutetiana appears to be diffused in the northern 

 hemisphere from to the 64° N. Lat. For Sibthorp found 

 it in the Bithynian Olympus, and Marshall of Biberstein in 

 Tauris. On the other hand, it is wanting in Lapland, where, 

 instead of it, the Circaa alpina grows. Its limits in North 

 America have not yet been exactly determined. But it seems 

 to grow from 40"* to the 50^ N. Lat.
