barren shoots than Mr. Coleman’s plant, and about the same 
amount of setze, aciculi and hairs ; its petioles and flowering shoot 
@re armed in the manner usual to the species. These plants are 
very nearly allied to those included in the preceding section, and 
might without much impropriety be placed init; but they are so 
closely connected by intermediate forms with the type of R. fusco- 
ater, and that through the var. echinatus with R. Kehleri, that I 
feel confident that this is their true position. Indeed the arma- 
ture of the barren shoots, if carefully examined, will be found to 
be rather that of this section than of the preceding. 
23. R. Kehleri (Weihe); caule decurvato procumbenteve hirto se- 
toso, aculeis multis validis inequalibus sepissime rectis, foliis qui- 
natis opacis subtus hirtis mollibus, foliolo terminali obovato vel 
elliptico acuminato, infimis intermediis dissitis, panicula ramosa 
inferne foliosa spinosa setosa, sepalis patentibus fructuve reflexis. 
a. Kehleri; aculeis permultis inequalibus rectis paulo declinatis, pilis 
paucis, foliolo terminali obovato acuminato, panicule superne tomen- 
tosz ramis corymbosis patentibus aculeis multis longis rectis.

The surface of the barren stem is almost covered by the very 
unequal prickles, aciculi and sete. Leaves pale green beneath, 
coarsely serrate ; general and partial stalks and midrib beneath 
very prickly ; stipules lmear. In a subvariety the leaves have 
fewer prickles on their midrib and stalks and linear-lanceolate 
stipules ; its barren stem is rather less prickly. In another form 
the prickles on the panicle are rather hooked. 
f. cuspidatus ; aculeis brevibus rectis horizontalibus, pilis paucis, fo- 
liolo terminali obovato cuspidato, panicule superne tomentose, ramis 
corymbosis brevibus patentibus setis multis aculeis paucioribus 
brevibus rectis.

I do not find a figure of this plant in the ‘ Rubi Germanici.’ Its 
aspect is considerably different from the typical R. Kehleri, and 
it may be known by its cuspidate leaves, which are usually deeply 
inciso-serrate at the end, and the fewer and shorter prickles 
throughout. I believe this to be the R. apiculatus from Beeston 
Castle referred to by Dr. Salter (Phytol. ii. 132). In some forms 
of this plant the leaves are very much truncated, and in a spe- 
cimen from Killarney, quite abrupt like those of R. Lingua. 
y- pallidus ; aculeis tenuibus rectis declinatis, pilis multis, foliolo ter- 
minali obovato-elliptico acuminato, panicule superne subtomentose 
ramis racemoso-corymbosis setis multis aculeis multis brevibus 
validis declinatis deflexisve.
