32 DROSERACEiE. * [Pamassia. 



Hab. Near Cumberland House, lat. 54°. Dr. Richardson. North-West Coast of America. Mr. Menzies, 

 Only two specimens of this are in Dr. Richardson's collection. The true D. longifolia, with seeds desti- 

 tute of arillus, and with shorter leaves than the present, I have received from New York and near Boston ; 

 but I have not seen specimens fi-ora Canada, where it is yet very likely to he found. 



3- D. linearis; foliis exacte linearibus obtusis sublonge petiolatis, petiolis longissimis 

 nudis, scapis radicatis l-S-floris, calycibus glabris, seininibus exarillatis la^vibus. (Tab. 

 XXVII. A,)—Goldie in Edin, Phil Joum. 1822. p. 325. De Cand, Prodr. v. 1. p. 318. 



Radix parva, fibrosa, annua, e fibris descendentibus simpUcibus, subfasciculatis, crassiusculis, nigris. 

 Folia omnia radicalia, subdigitalia, erecta, limbo duas fere tres unclas longo, duas lineas lato, exacte lineari, 

 obtuso, inferne in petiolum suhteque long^m, glahrum attenuato, margine dorsoque pilis longis patentibus, 

 ruhris, glandulosis tecto. Scopus solitarius, erectus, gracilis, glaber, dum florens, foliis subreque longus vel 

 paululum brevior, plerumque uni- nunc hi-triflorus, demum, fructiferus, folia cxcedens. Flores pedicellati ; 

 pedicelli breves, glabri. C«/^a; glaber, profunde 5-fidus. Capsula ovalis, calyce plusquam duplo longior, 

 ii-valvis. Semina ovali-oblonga, exarillata, laevia, nigra. 



Hab. Lake Simcoe, in Upper Canada. Mr, Goldie. It was found sparingly in fruit also in Upper Canada, 

 as well as plentifully in a SM'amp near Jasper's Lake in the Rocky Mountains, by Mr. Drummond. — It was at 

 my suggestion that Mr, Goldie, on his return from his travels in Canada, published the present plant as a new 

 species in the Journal above quoted. The form of the leaf alone did appear to me quite decisive of a specific 

 difference ; but the American Botanists, and especially Dr. Torrey, entertained a diflferent opinion, though I am 

 not aware that the plant is at all known to them ; and the able Botanist just mentioned has been disposed to 

 unite it with the D. longifoUa, It was therefore peculiarly gratifying to me to find amongst Mr. Drum- 

 mond's rich collection many specimens gathered in the Rocky Mountains, and all possessing the characters 

 detailed by Mr. Goldie, under his D. linearis. The name is singularly applicable; for from the blunt apex 

 nearly to the very base of the limb or blade, it retains the same width. It must not he confoimded with 

 the American D. filiformis (tenuifolia, WiUd. and Muhl.); which has the leaves vastly longer and filiform, 

 and which Dr. Toi-rey aptly compares to the rare and beautiful Drosophyllum lusitanicum.

Hab, Throughout Canada, as far north as the Arctic Circle, and among swamps in the Rocky Moim- 



tains, between lat. 52° and 56°. — Labrador and Newfoundland. Mr. Morrison. Kotzebue's Soimd and Bay 



of Eschscholtz. Ckamisso; and Messrs. Lay and Collie in Capt. Beechey*s Expedition. Cape Newenham. 



Nelson. — The broad, truly cordate, leaves, especially the cauline one, readily distinguish this from P. parvi- 



jiora ; and the numerous, slender, white pellucid hairs of its scale from all the other species of the genus.
