410 SHORT NOTES. 



densely tufted and taller than F. pusilla, which abounds in a wet 

 autumn in all the clover fields in the neighbourhood. The spores 

 are covered with high ridges or crests. Mr. Pearson, to whom at 

 the time I sent fresh specimens, said it was not F. caspitiformis, 

 which I had named it, but F. cristata Lindb. I was hoping to have 

 gathered further specimens, but not once during the last seven 

 years has the level of the water subsided sufficiently to expose the 

 clay bank, and there is no other suitable habitat at the locality. —

RuBi OF Streathaii and Tooting Commons. — Spending the 

 closing days of last August at Streatham, I was able to examine 

 the very numerous bramble- thickets on Streatham and Tooting 

 Commons pretty thoroughly. As these commons are so near 

 London, and most of the brambles on them are particularly well 

 marked and abundant, I have some hope that my lists may be of 

 exceptional interest. They are not, however, so nearly exhaustive 

 as they might have been had the season been less advanced. 

 Streatham Common : — R. idmis Linn., R. carpinifolius \Vh. & N., 

 R. Lindleianus Lees, R. enjthrinus Genev., forma (jlandulosa, R. 

 rhamnifollus Wh. & N. (our usual form, the R. caniiophyUus Lefv. & 

 Muell.), R. pulcherrlinns Neum., R. rusticanus Merc, R. piibescens 

 Weihe (sp. coll.) and its var. subinermis Rogers, R. leucostachys 

 Schleich., R. radula Weihe var. echinatoides Rogers, R. adoniatus 

 P. J. Muell., R. dametoruin Wh. & N. (a form or forms intermediate 

 betweeu vars. diversifoUus Lindl, and concinnus Warren), R. coryl'i- 

 foUus Sm. a. subliistris (Lees). Basides typical R. pulchenimm, the 

 highly glandular and aciculate form which we have been calling 

 var. selosus {s,QQ Juiini. Bot. 1891, 240; 1895, 48, 49) is locally 

 abundant, and keeps (as usual) very distinct from the type. Of 

 these fifteen strongly marked forms, the only ones that I did not 

 see in great quantity are idceus, Lindleianus, leucostachys, and sub- 

 liistris. Tooting Common : — All that are given above for Streatham 

 Common except (apparently) the var. setosus of pulcherrimus ; but 

 here R. Lindleianus is exceedingly abundant, and R. pulcherriinics, 

 R. pubescens, and R. adornatus far more so than on Streatham 

 Common. There are also the following additional forms : — R. 

 integribasis P. J. Muell., R. ajfinis Wh. & N., small typical R. radula 

 Weihe, very distinct-looking small-leaved states of R. carpinifolius 

 and R. rhamnifolius, and what seems a form of R. mucronatus Blox., 

 with terminal leaflet less mucronate than usual, and a rather ex- 

 ceptionally hairy stem. Tooting Common is a very good place for 

 studying most of the Rubi in these lists, as they grow there for the 

 most part in separate thickets or clumps, with extraordinarily little 

 intermixture of species. They were all known to me for Surrey 

 before, except R. inteyribasis, typical ii. radula, and the remarkable 

 glandular form of R. erythrinus, which is identical with plants which 

 I saw last year in West Kent, — at Sevenoaks and at Tunbridge 

 Wells. — W. MoYLE Rogers.
