Hab, Between Cumberland House and Hudson's Bay. Drummond. Kotzcbuc Sound. Captain 

 Beechey, Eschscholtz Sound. Mr, Von Cliamisso ; y. Labrador. Dr. Morison. — The variety /3. grows in 

 the Altai. See an account of the confusion of synonyms of this species in Chamisso and Schleehtendal 

 {LirmcBa \, p. 188.) where they have stated all points with their usual exactness. — The SwerticB o^ "^Ir , 

 Pursh are quite doubtful; his Swertia pusilla is certainly Sw. Stellerianay Cham. Schlecht. — another spe- 

 cies of PleurogynCy which I do not consider specifically distinct from Sw, Carinthiaca, Wulf; Mr. Pursh 

 states that he has seen specimens of it from Labrador in the Banksian herbarium, but as the variety y. of 

 PL rotata is indeed very similar to it, I did not deem it convenient to follow his statement, not having seen 

 specimens from that country. There are specimens of our plant scarcely an inch hi^h, the sepala being 

 sometimes larger than in the common form; Pleurogyne Stelleriana differs from them only by its blunt 

 ovarium, broader leaves, shorter sepala, and the insertion of theseeds being analogous to Gentiana. 



3. SWERTIA. L. 



FovecB epipetala^ glanduliferse, fimbriis cincta3. Stigma terminale, ovario impositum, 

 continuum, reniforme. Capsnla uniloculans, seminibus indefinitis valvulis affixis. Corolla 

 rotata pentamera absque corona. 



1. Sw. perennis (L.); caule basi ascendente, petalis elliptico-oblongis coriaceis sepala 

 lanceolata duplo superantibus, foveis binis, fimbriarum cristis distlnctis, seminibus alatis, 

 L. Sp. PL \.p, 328. Engi. Bot L 1441. Jacq, Austr. 3. t. 243.-/3. obtusa; petalis latt- 

 oribus obtusioribusj foliis radicalibus obtusioribusj caulinis plerisque alternis. 



Hab. (i. N.W. Coast. Mr. Menzies, — There is no difference from the Altaic form. I have examined 

 the same variety collected at Konigsberg, and its characters are not constant. — Swertia fastigiata, Pursh, 

 may be another species of this genus: it seems, however, more probable that it is a Frasera, as Mr Pursh 

 refers the genus to Tetrandria. 



4. FRASERA. Walt.

 Corolla rotata decidua tetramera.
