calyx of the fruit spreading or reflexed. Br. FL 1. p. 248. E. 

 Fl. v. ii. p. 408. E. Bot. t. 827. 



Hedges and thickets, frequent. Fl. July, Aug. J? . 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 quite sessile. Panicle very various, sometimes broad and co- 

 rymbose like that of R. 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 setae, 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. W. 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 0. Drupes of the fruit large, juicy, 

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



2. Stem herbaceous or nearly so. 



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

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

 Br. Fl. \.p. 252. E. Fl. v. ii. p. 410. E. Bot. t. 2233. 



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.

9. R. Charruzmorus, Linn. Cloud-berry. Dioecious; leaves 

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