particular with them. It is remarkable for the small size, and i<i\y nerves upon the petals, the calyx, in 

 almost every instance, overtopping the corolla, and for the leafless scape; or, if a leaf be present, it is 

 situated amongst the other leaves, and is always stalked. With the perfect flowering stems, there not un- 

 frequently appear, upon the same root, the stems and withered capsules of a former year, hut still possessing 

 the persistent remains of the calyx and corolla,

Hab. North-West Coast of America. 3Ir. Menzies. Elevated swamps in the Rocky Mountains, between 

 lat. 52° and 56°. Drummond. — Of this remarkable plant 1 have given a figure in the Botanical Miscellany ; 

 M'here, however, I have represented the fringe at the base of the petals rather as hairy or glandular pro- 

 cesses, than as formed by the substance of the petal itself, which it really is. On this and other species 

 of the genus, minute brownish dots are seen under a microscope, and particularly described, as common to 

 almost all parts of the plant in P. Kotzebuei, by Chamisso, sprinkling more especially the petals and scales. 

 Such were very evident on Mr. Meuzies's specimens of the present species, and are repesented in the Bot. 

 Miscell., but I do not find them in Mr. Drummond's. They are probably analogous to the dots in many 

 kinds of Viola, and are of the same colour in both, being sometimes present and sometimes absent in the 

 same species, or in diflferent parts of the same individual plant.

Calycis sepala persistentia, 2 interiora alaeformia. Petala 3-5 tubo stamineo connexa,

Obs. North America includes a very considerable number of species of this extensive and beautiful 

 genus; but they are chiefly confined to the United States, and are most abundant in the southern provinces. 

 The list of species in the Canadas is but small, and probably none has a more northern range than the 

 Saskatchawan, in lat. 52°, unless it he the P. Senega. None was found among the Rocky Mountains, and 

 none in North -West America.
