Low shrub, much resembling E. gracile; branches commonlystraight, with light colored bark; thorns mostly single, but veryshort, gray, like the outer bark; leaves wedge-shaped, deeply 3-5lobed, smooth or slightly downy, ciliate on the margins and veins,petioles pubescent, the hairs sometimes glandular-tipped whenvery young, peduncles short, 2-3-flowered, rather slender like thepedicels; calyx lobes narrow or oblong, greenish or dull purplish,much shorter than in R. gracile, apparently seldom reflexed; petalsobovate, small, fllaments longer than the calyx lobes, style 2-cleft,villous; berry small, smooth, agreeable.

The leaves correspond much better to the name rotundi-folium than do those of the more common form referred to thisspecies. The plant seems to approach B. curvata. Western Massachusetts and New York, southward to NorthCarolina along the Alleghanies. This appears to be unknown in cultivation, owing, no doubt,to the small size of its fruit. 17. R. LEPTANTHUM, Gray. (Fig. 89.) Sturdy, much branched, rigid shrub, 1-4 feet (3-12 decimeters)high, with grayish bark, and no prickles, thorns long, slender,single or triple, like the bark in color; leaves roundish, verysmall, 3^-% inch (6-15 mm.) in diameter, 3 5-cleft, t
