guishing characters of this little plant. It is more humble than 

 Nemacladus in that it spreads upon the ground, rising little above 

 its surface, but forming depressed tufts; but its white flowers are 

 comparatively conspicuous. Besides its peculiar habit and its ros- 

 ulate tufted spatulate leaves, the new plant differs from Nemacladus 

 mainly in its almost rotate and equally 5-cleft corolla, which is 

 shorter than the foliaceous lobes of the calyx; in the tube of the 

 latter being adnate up to the summit of the ovary; and in the de- 

 hiscence of the capsule by an operculum, the short conical apex 

 separating by circumcision. 



There is already a genus ParisJiia, an East Indian tree; so this 

 little herb must take the name in an altered and diminutive form. 

 The specific name might have been chosen from the desert habita- 

 tion or some characteristic feature of the plant; but it is fitting to 

 associate it with the name of the State in which the Messrs. Parish 

 reside, and the botany of which they have most largely helped to 

 make known. — Asa Gray. 



Notes from Canada. — Having in the latter part of June, 

 made a collecting tour with my friends. Professor Macoun, Domin- 

 ion Naturalist; Mr. Wm. Saunders, Editor of the Canadian Ento- 

 mologist; and Mr. James Macoun, to Point Pelee, Essex Co., On- 

 tario, the most southern point on the mainland in Canada, a list of 

 the rarer plants found there might not be void of interest to some 

 of the readers of the Gazette. The list is chiefly remarkable for 

 the southern nature of most of the species enumerated, some of 

 them so much so, that I hadnotdreamed of find" ing them within our 

 boreal confines. To this locality never before having been thoroughly 

 ' explored, may be attributed the seemingly extraordinary fact, that 

 or' the plants mentioned, the first eleven have not, I believe, been 

 heretofore recorded as found in Canada, while the remaiuing, ten 

 have but very rarely been noted.

The large size and plentitude of the Papaw, Mulberry, Blue 

 Ash, and Sour Gum trees clearly show them to be indigenous, and 

 would indicate that they are not*merely chance survivors, but that 

 the soil and climate fully meet their requirements. 



I might add, that during the week preceding our trip, Profes- 

 sor Macoun had found along Lake Erie, at Amherstburg, Pelee Is-
