30. R. KOEHLERI. 203 



Floimrlng shoot from fuscous scales, hairy, very prickly, 

 armed like the stem. Leaves ternate ; or upper floral leaves 

 simple, cordate-ovate or broadly three-lobed. Leaflets obovate, 

 the lateral acuminate, the terminal cuspidate, clothed and 

 toothed like those of the stem. Panicle rather long, very 

 prickly, usually with a broad convex top ; branches mostly 

 axillary, short, few-flowered, corymbose. Sepals ovate- 

 cuspidate, aciculate, setose, felted, leaf-pointed. Petals 

 broadly ovate, clawed, blunt, and slightly notched at the end, 

 pink. Filaments and styles faintly pink. Anthers greenish. 

 Primordial fruit-stalk short, shorter than the sepals, and as 

 well as the terminal fruit-stalks of the branches shorter than 

 the lateral stalks, which are erect-patent. 



The prickles on the panicle of this plant are often 

 exceedingly strong. One of the specimens of Leighton's 

 R. carpi iiijolius has the under side of its leaves felted. The 

 description of R. carpinifolius in the Flora of Shropshire 

 was drawn up from a comparison of that in Eng. Bot. Suppl. 

 (of a plant now combined with R. Grabowskii) with a speci- 

 men named R. carpinifolius by Borrer, but which is now- 

 believed to belong to R. Lindleianus. It is not therefore 

 wonderful that Leighton's description does not agree \vith 

 the specimens published as the R. carpinifolius of his Flora 

 in his Shropshire Ruhi. But I have strong reason to believe 

 that that specimen really represents the plant which he 

 always knew by the name of R. carpinifolius. 



It has often been suspected that this may be the R. 

 horridus (Hartm.) of Arrhenius. That plant is stated to 

 have a very hairy stem, leaves nearly always ternate and the 

 terminal leaflet subovate, sepals exceedingly prickly through- 

 out, whilst those of our plant have only a few acicidi at the 

 base. It seems to be confined to Scandinavia. My speci- 

 mens of it have no good barren stem. See R. diversifolius for 

 further remarks upon Hartmann's plant.
