166 SHORT DESCRIPTIVE NOTES ON THREE RUBI. 



cherrimus, R. anghsaxonicus, and R. viridis. For fully detailed 

 descriptions I must refer my readers to — F. "W. C. Arescboug, 

 'Some Observations on tbe Genus Rubus' (Lund, 1885-86); 

 Fridericbsen and Gelert, ' Danmarks og Slesvigs Kubi,' in Bot. 

 Tidsskr. (pp. 46, 65), torn. 16 (1887) ; Focke, « Synops. Eubor. 

 Germ.,' pp. 368, 369 (R. viridis and incultus). 



Eubus pulcherrimus Neuman (1882). R. polyanihemos Lindeb. 

 (non polyanthus P. J. Muell.). R. Neumani Focke. — Hooker's 

 name R. pulcherrimus, being a synonym of R. lineatus Eeinw., must 

 be dropped, and tberefore tbe plant can bear tbe name given by 

 Neuman. 



Tbe Swedisb autbors assert tbat in tbeir country tbis bramble 

 keeps quite distinct from R. Lindebergii P. J. Muell. Eitber species 

 agrees exactly witb forms placed under R. umbrosus by Englisb 

 botanists. R. pulcherrimus bears more or less numerous (often a 

 few scattered only) glandular seta3 on tbe panicle ; its prickles are 

 of a moderate size ; and in a living state it will be distinguisbed 

 from tbe true umbrosus at first sigbt by its pink flowers. Tbe two 

 species or varieties agree in tbe roundisb sbape and tbe small 

 superficial dentition of tbe leaflets. A careful examination of tbe 

 living plant will sbow if it can be separated from tbe eglandular 

 wbite-flowering umbrosus. 



E. anglosaxonicus Gelert. — By many cbaracters tbis species 

 seems to be intermediate between R. mucronatus and R. Radula. 

 Usually tbe stem bears a good many aciculi, wbicb are often 

 somewbat unequal in size, but always very distinct from tbe strong 

 prickles confined to tbe angles. Tbe leaves are ternate or pedato- 

 quinate, tbe leaflets coarsely serrate and generally wbite-felted 

 beneatb, tbe terminal one ovate or elliptic, witb a sborfc point. 

 After flowering, tbe sepals are patent. Tbe inflorescence is very 

 glandular. 



Tbe stems of R. Radula are mucb rougber, from numerous equal 

 aciculi ; its leaflets are narrow and acuminate ; and its sepals are 

 usually reflexed. R. mucronatus will be easily distinguisbed by tbe 

 sbape and serrature of its leaflets. 



E. viridis Kaltenb. (1845). — Tbis species recalls typical R. 

 pallidus W. et N., but it may be easily distinguisbed by its unequal 

 prickles. Tbe true R. pallidus, a rare plant in England, belongs to 

 tbe radula group, and bears nearly equal prickles well discriminated 

 from tbe aciculi. R. viridis migbt, I tbink, be put by Professor 

 Babington under bis R. Koehleri var. pallidus ; and indeed it is 

 difficult to trace certain limits between R. Koehleri and R. viridis, 

 altbougb tbe typical forms look very different. I consider tbe 

 R. incultus Muell. et Wirtg. (1862) to be a more bairy and very 

 prickly variety of R. viridis, and it is, I believe, mucb more frequent 

 tban tbe typical plant as well in England as in Western Germany. 

 R. viridis and its allied forms are connecting links between tbe 

 Radula' and tbe Glandulosi.
