barren shoots tban Mr. Coleman's plant, and about the same 

 amount of setae, aciculi and hairs ; its petioles and flowering shoot 

 are 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 in it ; but they are so 

 closely connected by intermediate forms with the type of R. fusco- 

 ater, and that through the var. echinatus with R. Koehlerij 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. Kcehleri (Weihe); caule decurvato procumbenteve hirto se- 

 tose, aculeis multis validis incequalibus ssepissime 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. Kcehleri ; aculeis permultis incequalibus rectis paulo declinatis, pilis 

 paucis, yb/^o^ terminali obovato acuminato, paniculse superne tomen- 

 tosse ramis corymbosis patentibus aculeis multis longis rectis.

The surface of the barren stem is almost covered by the very 

 unequal prickles, aciculi and setse. Leaves pale green beneath, 

 coarsely serrate ; general and partial stalks and midrib beneath 

 very prickly ; stipules linear. 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. 



/3. cuspidatus ; aculeis brevibus rectis horizontalibus, pilis paucis,/o- 

 liolo terminali obovato cuspidato, paniculse superne tomentosae, 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 difierent from the typical R. Kcehleri , 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, paniculse superne subtomentosae 

 ramis racemoso-corymbosis setis multis aculeis multis brevibus 

 validis declinatis deflexisve.
