368 Dr. T. Bell Salter on some forms of Rubus. 
9. y. Reichenbachii.—Aciculi and sete few on the barren stem. 
Leaflets suborbicular.

This is a very remarkable bramble, characterized generally by 
the darkness of the stem, which may be described as of a fusco- 
ater tint, and except in the form y. 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 
setee or aciculi. Aciculi short, equal both among themselves and 
to the dense clothing of hairs and sete. The panicle is extremely 
large, much-branched and leafy. The prickles of the panicle are 
long, and except in @. 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 sete, 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. 8. Leightonii 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 8. The descriptions of 
both, in Leighton’s ‘ Flora,’ under the synonyms above given, 
are excellent. 
The var. y. Reichenbachii is the most distinct form, and regard- 
ing only the barren shoot, might appear, from the different shape 
of the leaf, which is of a corylifolius form, and from the paucity 
of sete, 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 setee. Aciculi, sete and hairs numerous and 
unequal. Leaves quinate ; leaflets obovate, acuminate, finely 
and unequally serrated, green and channeled above, pale and
