sends specimens, collected by Mr. Robbins at Cambridge, Vermont, which 

 are said to bear fruit intermediate between the two, and the liabit of the 

 plant is apparently intermediate. " It is distinguished by the inhabitants, 

 and was pointed out by them." The specimens seem to belong rather to 

 R. strigosus. R. occidentalis, Schlecht. ! (in Lirineea, 13. p. 271) from Mexi- 

 co, is a different species. 



1.5. R. leucodermis (Dougl. ! mss.) : glaucous, armed with very strong 

 recurved prickles; stems erect; leaves 3-foliolate or sometimes pedately 

 5-foliolate ; leaflets broadly ovate, incised and serrate, acute, canescently 

 tomentose beneath; stipules setaceous; peduncles axillary and terminal, 

 few-flowered ; petals nearly the length of the sepals ; fruit large, brownish- 

 black with a white bloom. — R. occidentalis 0. Hook. fl. Bar. -Am. 1. p. 

 178. 



Oregon, Douglas ! Nuttail ! — The specimens received from Dr. Lindley 

 and from Mr. Nuttail appear to differ from R. occidentalis in the numerous 

 and remarkably strong prickles, larger, broader, and more incised leaflets ; 

 the latter when more than three being pedate, with the 3 upper leaflets 

 much petiolulate, the two k)wer smaller and nearly sessile. The fruit, ac- 

 cording to Nuttail, has the same flavor as R. occidentalis, but is covered with 

 a copious bloom. 



16. R. spectahilis (Pursh) : unanned or with deciduous prickles, erect ; 

 stem and branches terete ; leaves nearly glabrous, 3-foliolate ; leaflets ovate, 

 acuminate, membranaceous, somewhat pinnatifid-incised, serrate ; the lateral 

 leaflets distant from the terminal one, subsessile, often deeply 2-lobed ; sti- 

 pules setaceous ; peduncles solitary or in pairs, 1-2-flowered ; sepals hairy 

 at the base, broadly ovate, with a short acumination, much shorter than the 

 oblong (bright red) petals; fruit large, yellowish or red. — Pursh! fi. 1. p.

In shady woods near streams, Oregon ! and N. W. Coast ! to Unalaschka ! 

 & Sitcha ! common near the ocean. — Shrub 6-10 feet high. Flowers very 

 large. Fruit ovoid, red, more than twice the size of that of R. Idaeus, but 

 much inferior in flavor, Chamisso, (oblong yellowish-white and well-flavored, 

 Douglas : " varying from amber-yellow to cherry -red, highly translucent, 

 but neither abundant nor very finely flavored, being rather watery and acidu- 

 lous." Nuttail.) Styles long and somewhat persistent.

 oblong.) — (Blackberry.) 



17. R. villosus (Ait.) : stem erect or reclined, angular, armed (as well as 

 the petioles and often the midrib of the leaflets) with stout cur^-ed prickles ; 

 branches, peduncles, and lower surface of the leaves tomentose-villous and 

 glandular; leaves 3-foliolate or pedately 5-foliolate; leaflets ovate or oblong- 

 ovate, mostly acuminate, doubly or unequally serrate ; the terminal one con- 

 spicuously petiolulate and mostly subcordate ; stipules linear or subulate ; 

 peduncles many-flowered, the flowers racemose ; bracts many times shorter 

 than the pedicels ; sepals with a linear acumination, much shorcer than the 

 obovate spreading (white) petals; fruit large, black. — Ait..' Kew. (ed. 1.)
