themselves would have little significance. Moore himself points out that tne 

 habit of the plant is variahle and that it cannot he regarded as a universal 

 endophyte, while the presence or absence of a colourless tube is of little 

 consequence. 



Three other species have been established by Scliroetor, but the information 

 o-iven about them is so scanty that it would be pracfically impossible to 

 identify them again. It is possible that they may belong to certain other 

 species already described, but in the absence of the original paper * it is 

 impossible to determine their affinities. 



XT. Chlohocmiytrium L/ETUM, Schroet. (1883). 

 This species is endophytic in the leaves of Lychi'is Flos-mcuU. 



XII. Chlorochytkium viride, Schroet. 



This alfra occurs in the leaves of Rumex oUu&ifolius in Silesia, giving a 

 red colour to the epidermis of the host. 



XIII. (yHLOROCHYTRiUM RUBRUJI (Schroet.), Freeman. 



The alo-a trvows in the intercellular spaces of the leaves of Mentha aquatlca 

 and Pq)Us Fortida, on which it produces tubercles wliich are eithi'r irrc- 

 (Tularly globose or ovoid and are often red. It was originally described by 

 Schroeter in 1883 as Endosphum rubra, but Freeman in 1898 transferred it 

 to the genus Chlorochjtrium.
