short r/z/^r>OT(' and nodulose rootlets; leaves interruptedly pinnate, 

 leaflets cut into narrow serrated segments ; flowers in crowded, 

 erect, compound cymes, pink externally in bud, when open, white 

 and scentless. — Dry pastures on a limestone soil. Distinguished 

 from the preceding by its elegantly cut foliage, pink buds, and 

 whiter, scentless blossoms. A double flowered variety is common 

 in gardens. — Fl. June, July. Perenniah

 scattered, stipulate ; _/'('7f'(7\ in terminal and axillary clusters, rarely 

 solitary, white or pink ; sepals 5, persistent ; petals 5 ; carpels

1. Ji. Idd'iis (Raspberry). — A shrub with many suckers, and 

 nearly erect, round, glaucous, prickly : stei/i : leaves pinnate, of

 when ripe. — Rocky woods; common. The origin of the garden 

 raspberry, which differs but little from it. — Fl. May — August.

2. R. fniticosiis {y>iM'\'\h\s, or Blackberry). — The collective name 

 for a large number of closely allied forms, which, though many 

 of them have fairly definite distinctive characters, are difficult to 

 discriminate. They agree in being shrubs, without suckers, with 

 prickly stems; leaves of 3 — 5 leaflets arranged palmately or 

 pedately ; jlojuers m erect compound jianicles ; and fruit claret- 

 colour or black, not separating from reseptacle when ripe. Nearly 

 a hundred species have been described, as British, besides many 

 named varieties ; but it will be sufficient here to describe the 

 nine maui groups under which these puzzhng forms are arranged. 

 Group I., Snberectl — Stems usually sub-erect, rarely rooting at the 

 tip, glabrous or very slightly hairy, without bristles or gland-tipped 

 hairs, \\\\.\\ prickles mostly equal and canfined to the angles of the 

 stem ; stipules linear ; leaves, when malure, green beneath ; sepals 

 green, with narrow white margin ; drupels numerous. Group II., 

 Rhauiuifolii — Stems liigh-arching, often rooting froar a callus at 

 the tip and thus giving rise to a multitude of individuals, glabrous, 

 or with few hairs, usually without stalked glands ; prickles mostly 

 equal and confined to the angles ; iepals grey, or white felted, 

 with no conspicuous white margin, olten reflexed in fruit : fruit 

 large, black, juicy. Group III., Discolbres — Stems arched or 

 prostrate, rooting at tile end, with adpressed hairs and eL]ual, 

 strong prickles, with no stalked glands ; leaices i|uinato, white-felted 

 beneath ; ief'als grey, reflexed in fruit ; petals often pink ; drupels
