368 Dr. T. Bell Salter on some forms of Rubus. 



9. 7. Reichenbachii. — Aciculi and setae few on the barren stem. 

 Leaflets suborbicular. 



Hob. Spring Vale near Ryde, Mr. Thomas Meehan, 



Syn. R. Reichenbachii {Kohler), Rubi German, p. 87. tab. 37. 



This is a very remarkable bramble, characterized generally by 

 the darkness of the stem, which may be described as of afusco- 

 ater tint, and except in the form 7. by the extreme jaggedness of 

 the leaves, which are of a deep dark green above; also by the 

 length of the pedicels of the leaflets, in some cases little less 

 than that of the leaflets themselves. The prickles are pungent, 

 generally clothed with silky hairs, nearly equal, not passing into 

 setse or aciculi. Aciculi short, equal both among themselves and 

 to the dense clothing of hairs and setce. The panicle is extremely 

 large, much-branched and leafy. The prickles of the panicle are 

 long, and except in fi. slender and nearly horizontal. Rachis very 

 setose. Leaves of the panicle ternate below, passing by means of 

 broad simple leaves with large stipules into leafy ternate bracteas. 

 Bracteas hairy, upper ones very setose. The calyx has a few 

 prickles, is thickly clothed with dark-coloured setse, and has most 

 generally a leafy point, is much reflected, and even strongly re- 

 pressed on the peduncle when in fruit. This long reflected calyx 

 gives a decisive character to the plant. The fruit is oblong, large 

 and shining. The flowers are small, usually white. 



The var. ^. Leiyhtonii is characterized by that form of leaflet 

 spoken of in the general observations above as the abrupt form. 

 The prickles of the panicle have broader bases, and are falcate or 

 decurved, and those of the barren shoot, which is not so dark as 

 in the other forms, are slightly unequal. Though these differ- 

 ences in the well-marked variety are considerable, yet I have spe- 

 cimens, collected in the Isle of Wight, which I scarcely know 

 whether to refer to the first form or to /3. The descriptions of 

 both, in Leighton^s ^ Flora,^ under the synonyms above given, 

 are excellent. 



The var. 7. Reichenbachii is the most distinct form, and regard- 

 ing only the barren shoot, might appear, from the diff'erent shape 

 of the leaf which is of a corylifolius form, and from the paucity 

 of setce, to be a separate species. All the parts however of the 

 inflorescence and fructification accord with the normal form, and 

 there are intermediate states. 



10. Rubus Radula (Weihe). — Stem arched, slightly angled and 

 striated. Prickles with thick bases, unequal, declining, passing 

 insensibly into setse. Aciculi, seta and hairs numerous and 

 unequal. Leaves quinate; leaflets obovate, acuminate, finely 

 and unequally serrated, green and channeled above, pale and
