 westward through the provinces of New Brunswick, Quebec, and Ontario. Banks along 

 the roadside at the Rifle Range, Bedford, N.S. — Lawson. London, Ont.^ — ■Millmati, 13th 

 August, IStit, Herb. Can. Survey. In the townships in rear of King.ston, in Frontenac 

 and adjoining counties, as between Kingston and Odessa, Waterloo, and Hinchinbrook ; 

 also Toronto. — Lainson. Windsor, N. S. — Prof. Hoiu. Nicolet and St. Johns, Q., and

 Ottawa and I'rescott Railway, abundant ; rare in thickets northward to Chelsea. — Mr. B. 

 Billings jr. Belleville, abundant in low grounds, along small streams ; also Thunder Bay, 

 Lake Superior. — Macoun. Red Lake River, September, 1860. — Dr. Sclmltz. Provancher 

 cites Pied du Cap Tourmente and Isle Yerte, which is the last outpost north-eastwardly. 



Mr. Barnston observes that westwardly this species does not appear to pass the longi- 

 tude of Red River or Lake Winnipeg, and is rare to the N.W. of Ontario Province. South 

 end of Lake Winnipeg. — Drummo/td. Canada to Greorgia, and west to the Mississippi. — 

 T. and G. Said by Sir John Richardson to be coumon to Oregon, the eastern United 

 States and Canada, and to extend northwards to the Saskatchewan ; but Sir John no 

 doubt included the form ligiisticifolia, which, although described from Nuttall's Notes in 

 Torrey and Gray's Flora, was not then well known or generally recognized as a species. 



Hooker observed that this had been long cultivated in England, where it proved a 

 hardy plant, well adapted for covering walls and arboiirs. Its flowers are highly fragrant, 

 which is not usual in this geni\s. The first notice of its ciiltivation in England is in 

 Hortus Kewensis, " 1*76*7, by Mr. James Gordon." 



3. — Clematis ligusticifolia, Nuttall. 



Stem shrubby, trailing or climbing. Leaves pinnate and five-leaved, or teruate, occa- 

 sionally seven-leaved; the leaflets oval, oblong or lanceolate, from broad to A'ery narrow, 

 tri-lobed or with few distant teeth. Inflorescence in close pauicled corymbs, flowers on 

 long, slender pedicels, dioecious. Otherwise as C. Virginiana. In Professor Macoun's 

 specimens from source of the Qu'Appelle the leaves are pinnate, the leaflets short, as 

 broad as long, and shortly stalked, inflorescence corymbose. In a form (apparently of this) 

 collected in May, 1883, near Canyon City, Colorado, the leaflets are narrowly oblong- 

 lanceolate, A-^ery acuminate, with a few distant teeth.
