96 11. R LATIFOLITJS. 



ship. It much resembles some states of R. corylifolius in 

 foliage; but differs by its deeply furrowed stem, want of felt 

 on its leaves, prickles confined to the angles of the stem, and 

 the total absence of aciculi and setae. The panicle also wants 

 the long spreading branches which are usually conspicuous 

 in R. corylifolius. 



Mr Kirk justly remarks {Phytol. iv. 969) that the plant 

 found near Thirsk to which I once gave the name of R. 

 latifolius is not distinguishable from R. corylifolius P con- 

 jungens. I have only seen one specimen of it. He says 

 that it sometimes has a furrowed stem, which is unusual in 

 R. corylifolius. Its leaves are very different from those of 

 the true R. latifolius. 



Mr Lange quotes a specimen named R. latifolius by me, 

 as belonging to the R. Wahlbergii (Arrh.). As I do not 

 know from whence the specimen was obtained, it is possible 

 that it may be the misnamed plant from Yorkshire. In my 

 opinion the it. Wahlbergii is not distinguishable from my 

 R. corylifolius /3 conjungens. 



The fact that this plant has been noticed in only three 

 or four places and in very small quantity renders it probable 

 that it is an abnormal state of some better understood 

 species. Its fruit is unknown. If a distinct species its true 

 place in the genus is not yet determined. It associates very 

 badly with the Rhamnifoliiy although agreeing with them in 

 technical characters.
