As it is of some importance to know where the examined specimens are to 

 be found, I have, in order to state this, used the following abbreviations: 



HB. =- Herbarium Musei Ijotanici Berolinensis. 

 HC. -= Herbarium H. Christ, Basel. 

 HH. = Herbarium Musei botanici Hauniensis. 

 HR. ^-= Herbarium E. Rosenstoci<, Gotha. 



HS. = Herbarium Holmiense (Herbarium Regnellianum and Riksmuseels Herba- 

 rium, Stockholm).
