CL. VII.] 12. TRIENTALIS EUROPyEA. 3^9 



peculiar membranaceous, glandular circle, commonly seven 

 filaments, almost of the size of hairs, somewhat shorter than 

 the corolla, and bearing curved anthers. The germen is su- 

 perior, and has a simple pistil. The fruit is a spherical, dry 

 berry, the seeds of which are fastened to a spherical cavity. 

 The embryons stand upriglit in the albumen. 



Affinity. 



Although the external appearance of this plant corresponds 

 with that of the Stellariac, the situation of the embryon, how- 

 ever, is completely different. In the Stellariac, the curved 

 embryon surrounds the central albumen ; in the Trientcdisj 

 it stands upright, almost in the axis of that substance. By 

 this circumstance, our plant becomes associated with the Ly- 

 simachia?, AnagaUiSy and the family of the Primuleae. The 

 peculiar numerical proportion probably arises from an imper- 

 fect union of two flowers (185.) ; in consequence of which, 

 instead of ten, there are only seven divisions of the calyx, 

 seven petals, and seven anthers. However, there are ex- 

 amples of five, six, and ten filaments.

Geographical Distribution. 



Few plants are found so far north as diis. For it is found 

 at the North Cape, and in Siberia on the Lena, under the 

 70° N. I.at. It grows also in North America as far as Hud- 

 *!on's Bay, but with smaller, and more sharply pointed leaves.
