1921] Fernald, — Expedition to Nova Scotia 269 



less pubescent than R. allegheniensis, though with the lower leaf- 

 surfaces thinly velvety; the racemes (except at tip of cane) copiously 

 leafy-bracted, and the sparingly glandular pedicels more often with 

 scattered bristles; in these characters closely matching the scries of 

 Blanchard's Cape Porpoise specimens designated by him as the type. 

 Heretofore known from York Co., Maine and from Cape Cod, Mas- 

 sachusetts. Digby Co.: rich moist open thicket by brook, Sandy 

 Cove, Fernald k Long, nos. 21,589, 21,592, 21,(502. Yarmouth Co.: 

 gravelly shore of Lake Annis, Bisscll, Pease k hinder, no. 21,568;

 Fernald, Long k Linder, no. 21,609; damp rocky thicket, Pubnico, 

 Fernald, Long k Linder, no. 21,(513. Shelburne Co.: rocky spruce 

 and alder thickets, and drv gravelly slopes, Shag Harbor, Fernald, 

 Bissell k Linder, nos. 21,581, 21,(517 and 21,628.

 woods and thickets near Butler's (Gavelton) Lake, Gavelton, Fern- 

 ald, Long k Linder, no. 21,540; moist clearing in spruce woods near 

 Itandel Lake, Argyle, Long k hinder, no. 21,(524. 



** R. amnicola Blanchard, Rhodora, viii. 170 (190(5) as R. amni- 

 coins. The type collection is well matched by our material from 

 Digby Co.: gravelly railroad bank, Digby, Bissell, Pease, Long k 

 Linder, no. 21,(525. 



Brainerd & Peitersen treat R. amnicola as a hybrid of It. argutus 

 and R. canadensis. As yet no typical R. argutus has been found in 

 Nova Scotia, the nearest approach to it being R. Andrewsianus 

 which they consider a hybrid of R. allegheniensis and R. argutus. 



It. canadensis L. Common throughout the province. 



It. multiformis Blanchard. Blanchard included different plants 

 under this name. The typical species is a very distinct low-arching 

 or trailing, freely branching and "tipping" shrub, with remotely 

 prickly coarse canes, glabrous leaves with caudate-tipped leaflets 

 and very lax and elongate racemes (suggesting those of R. elegantulus) , 

 the filiform pedicels not bristly. The following Nova Scotia mater- 

 ial closely matches Blanchard's type series. Kings Co.: Kentville, 

 Blanchard, no. 72(5. Annapolis Co.: Annapolis, Blanchard, no. 

 727. Digby Co.: thickets bordering savannahs by Little River,
