The last three species as well as Melampsora larici-tremulae Kleb., 

 all of which have st. II and st, III on the leaves of Populus tremula 

 were — when their biological circumstances were found — separated 

 into just as many species as forms of caeoma were found, although all 

 three stadies were quite alike morphologically. Now Bubak has pro- 

 posed (99^*) that they should be considered as one species, divided 

 into more"Anpassungs-Formen". Rostrup also writes (02 a '^^°) that they 

 may be considered as biological species. 



1371. Melampsora hypericorum (de C.) Schroeter, Perikonrust 

 (R 04 a 52). 



Was formerly always considered a hemi-melampsora ; according to 

 the experiments of Tranzschel and Klebahn (05 b ^"^ c. icon.) this 

 species must also be divided into more formae speciales of different 

 cycles of life; the form on Hypericum humifusum has uredo and te- 

 leuto, but the form found on the other species of Hypericum has 

 caeoma and teleuto.
