7. R. echinatum : aculeis quinis axillaribus, ramis omnino rcclinatis hispidulis, 

 foliis 5-lobis glabris, raccmis nutantibus multifloris folio, longioribus, pediccllis 

 germinibusque piloso-glandulosis, calycibus campanulatis, bractcis ovatil oKaftis, 

 baccis hirsutis. 



Branches slender, reclining, rarely divided, thickly clothed 

 with long sharp, bristly, brown prickles ; these are five or 

 seven in number, large, long, flattened, and combined under 

 the buds. Leaves five lobed, smooth on both sides, un- 

 equally toothed, on slightly pilose petioles, which are shorter 

 than the leaves. The flowers hang in a lax, slender raceme, 

 nearly double the length of the leaves ; the partial footstalks 

 and germen covered with brown glandular hairs ; bractea? 

 ovate, half the length of the pedicels. Calyx bell-shaped, 

 with rounded, spreading and somewhat reflected segments, 

 brownish-yellow, with a dark rim, scarcely longer than the 

 rounded petals. Berries black, hairy, small, of a pleasant 

 taste. 



This species in several respects is nearly related to R. 

 lacustre. The depressed habit, the much more copious cloth- 

 ing of longer and stronger prickles, the less divided and 

 perfectly smooth leaves, the black-rimmed calyx and black 

 fruit, render it truly distinct. I have not seen R. armatum 

 of the Linnean Herbarium, but I suspect that species to be 

 still more nearly akin to the one now noticed. 



It is a common trailing shrub, on dry shelving rocky places 

 on the mountains, at the Grand Rapids on the Columbia, and 

 on the mountains of Northern California, never frequenting 

 edges of rills or swampy ground in shady woods among 

 Carices as R. lacustre does. This species flowered for the first 

 time last April, in the Society's Garden.
