Subdiv. iii. Rubi Villosi. 



JR. calvatiis, Blox. Stem angular, sulcate, with few, spreading 

 hairs (quite denuded in the upper part) ; prickles many, declining, 

 irregularly scattered ; leaves quinate, with hairy petioles, green on 

 both sides, almost bald, the ribs and veins beneath only inconspicu- 

 ously ciliated ; leaflets all stalked, the basal pair retrose, terminal one 

 ovate, cordate at the base, sharply and deeply apiculate, dentate, acu- 

 minate ; rachis deeply ribbed, clothed with stiff, spreading hairs ; 

 panicle long, flexuous, with many corymbose branches, gradually 

 shortening and leafy nearly to the summit ; peduncles densely hairy, 

 closely armed with long pale prickles ; sepals tomentose, loosely 

 reflexed. In exposed thickets, but not very general. Near Tw^y- 

 cross, Leicestershire ; and found by the Rev. Andrew Bloxam in 

 several parts of that county, and in Warwickshire. Precisely similar 

 specimens the late Mr. R. E. Wilson sent me from Cheshire. Also 

 near Ilfracombe, Devonshire. 



A large, remarkably savage-looking and strong bramble, whose 

 stem becomes quite denuded ; and the leaves are singularly bare, a 

 few scattered hairs only being scarcely discernible on the veins and 

 ribs beneath. The central leaflet is often exactly ovate, and very 

 regularly, but deeply, apiculate- dentate, gradually acuminate ; panicle 

 very long, with rough, hairy, and closely prickly branches, leafy 

 throughout, and frequently widely divaricated at the summit. This 

 was formerly confounded with R. villicaulis, W. Sf N. ; but the latter 

 has its barren stem densely covered with white hairs, its leaves tomen- 

 tose, and the branches of its panicle mostly ultra-axillary. It is not 

 uncommon in woody spots. Plentiful in Caernarvonshire, and south- 

 ward to Dorsetshire. 



Subdiv. iv. RuBi Pilosi. 



R. Sprengelii, W. & N. Stem prostrate, round, clothed with long 

 spreading hairs ; prickles small, weak, hooked or deflexed, and dis- 

 persed unequally on all sides ; leaves mostly ternate, thin, smooth 

 above and beneath ; leaflets elliptical, central one obovate, sharply 

 serrate, acuminate, with prominent veins beneath ; panicle slender, 

 with crowded, divaricate, leafy branches ; the peduncles closely 

 covered with attenuated, tortuous hairs, concealing both setae and 

 prickles ; petals small, obtuse, and rugose. In thick woods, ra- 

 ther local. I have gathered it in Buckinghamshire, Devonshire, 

 Gloucestershire (forest of Dean), Leicestershire, Warwickshire, and
