Hedges and thickets, frequent. Fl. July, Aug. T? . — Stem biennial ; 

 the barren ones very long and trailing, unless accidentally supported, 

 sometimes arched, glaucous and purplish, green in the shade. Prickles 

 usually straight, a little deflexed. Setce few or none, except about the 

 inflorescence, and these distinct from the prickles. Leaflets broadly 

 ovate, with a cordate base, soft, hairy, paler or sometimes hoary at the 

 back ; intermediate pair on short stalks, on which the external pair is 

 usually cpiite sessile. Panicle very various, sometimes broad and co- 

 rymbose like that of JR. ccesius, but less so than in most other species. 

 Flowers white. A beautiful variety of this is found in the County of 

 Derry by Mr. Moore, with large soft leaflets, of a rounder form than 

 usual, and purple shining stems. 



7. R. ccesius, Linn. Dewberry. Stem prostrate, round or 

 nearly so, glaucous : prickles straight, unequal, passing insensi- 

 bly into seta?, the length of the largest rarely equalling the dia- 

 meter of the stem ; leaves digitate of three or more, rarely five 

 ovate leaflets, the outermost sessile ; calyx embracing the fruit.

/3. Stem stronger, obsoletely angular, leaflets generally five. 

 R. dumetorum. TV. and N. 



Bushy places and borders of fields, frequent. Fl. June, July. T? . — 

 Stem weak, with many slender branches rooting at the extremities. 

 Prickles usually straight, scarcely deflexed, varying in size and dimi- 

 nishing gradually, so as not to admit of a distinct line of separation 

 between them and the setce, with which the plant is also furnished. 

 "Leaflets broadly ovate, often lobed, pubescent above, more so and 

 softer beneath, and of a paler colour, sometimes covered with long 

 shining hairs ; the outermost sessile, or with only hardly distinguishable 

 stalks. Panicle corymbose ; the divisions frequently cymose. Flowers 

 few in a. more numerous in (3. Drupes of the fruit large, juicy, 

 black, with a fine glaucous bloom and agreeable acid flavour. 



2. Stem herbaceous or nearly so. 



8. R. saxatilis, Linn. Stone Bramble. Leaflets 3, slightly 

 downy, runners creeping, herbaceous ; panicle of few flowers.

Stony mountainous places, more plentiful in the north ; it is also to 

 be met with about Killarney and in the County of Galway. Fl. June. 

 %. — Erect, slender, eight or ten inches high, with a few weak straight 

 prickles on the stem. Leaves two to three ; leaflets ovate. Petals 

 minute, narrow, greenish yellow. Fruit of very few, red, (compara- 

 tively) large clustered drupes.

 simple, lobed ; stem without prickles, herbaceous, single flowered.
