 Also Labrador ! Newfoundland ! Saskatchawan in lat. 53°, and Rocky 

 Mountains! — " Berries amber, very deliciou?," Pursh. (The fruit seldom 

 ripens in Lapland.) — The remarks of Chamisso and of E. Meyer are con- 

 firmed by the specimens before us. The pistils, according to the latter, are 

 approximate in the sterile plant, and the filaments somewhat dilated. 



' 10. R. pedatus (Smith) : stem creeping and flagelliform, branching from 

 the base, herbaceous, filiform ; leaves 3-foliolate, or i)edately 5-foliolate by 

 the division of the two lateral leaflets, membranaceous, nearly glabrous ; 

 leaflets obovate, incised and serrate ; stipules roundish, scarious, persistent ; 

 peduncles filiform, mostly bibracteate, 1-flowered; sepals ovate-lanceolate, 

 entire or serrate-incised, at length reflexed, nearly the length of the obovate- 

 oblong often crenulate sessile (white) petals ; carpels 3-C, large and pulpy 

 (red) in fruit. — Smith! ic.ined. t. 63 ; Pursh ! I. c. ; Hook. ! Jt. Bor.-Am. 1.

 Menzies ! Eschscholtz! Mr. Ihlmie ! Sitcha, Bongard! Oregon, Douglas ! 

 Dr. Scouler ! and in the Rocky Mountains between lat. 52° and 56°, Drum- 

 mond ! — Differs from the present genus only in the few carpels, and in want- 

 ing the protuberant receptacle ; and from Dalibarda only in the pulpy fruit 

 and divided leaves : but several species of Rubus of very different habit 

 among themselves also have the carpels reduced to about 6 or 8. It differs 

 essentially from Comai'opsis. There are 2 suspended ovules in each ovary, 

 one of which is abortive, as in the rest of the genus. 



11. R. saxatiiis (Linn.): herbaceous; flowering stems simple, erect; 

 stolons prostrate and sterile ; leaves 3-foliolate, on long petioles, somewhat 

 pubescent ; leaflets rhomboid-ovate, mostly obtuse at both ends ; ^^eduncle 

 3-8-flowered ; pedicels short, and, with the calyx, pubescent, but not glan- 

 dular; sepals at length reflexed, as long as the petals; fruit red, composed 

 of few very large grains. — Linn.! spec. 1. p. 494; Engl. hot. t. 232; DC. 

 prodr. 2. p. 564. 



Greenland, Hornemann ! — This species seems not to have been found in 

 any part of the American continent proper. 



-' 12. R. trijiorus (Richards.): unarmed; stem suffiutescent at the base, 

 ascending, the branches herbaceous, often flagelliform ; leaves 3- (sometimes 

 pedately 5- ) foliolate, on slender petioles ; leaflets membranaceous, almost 

 glabrous, or pubescent beneath, rhombic-ovate or somewhat ovate-lanceolate, 

 acute at both ends, often acuminate, coarsely doubly serrate, often somewhat 

 incised ; the terminal one petiolulate ; stipules ovate, entire ; peduncle termi- 

 nal, 1-3-flowered ; the pedicels elongated, and, as well as the calyx, minutely 

 glandular; sepals (5-7) lanceolate, acute or acuminate, at length reflexed, 

 rather shorter than the spatulate-oblong erect (white) petals ; fruit small, 

 red. — Richards. ! appx. Frankl. journ. ed. 2. p. 19 ; Hook.! Jl. Bor.-Am.
