It is most likely that all the species of Puccinia occurring on the 

 species of Carex are heteroecious, and this has now been proved by 

 experiments for many species; concerning a number of species of 

 Carex it is, however, not yet known among which species the uredo — 

 and teleutospore — form occurring on them must be classified; the 

 morphological signs give but little information as they are almost all 

 very much alike. So I shall be obliged to state a number of forms 

 under the name of Puccinia caricis although it may later on be proved 

 that these forms should be named differently.

Heter-eu-puccinia, st. I very common in May— June on leaves and 

 fruit of Ribes, st. II <S^ III on leaves and stems of Carex during the 

 rest of the year; the species is distributed all over the country, and, 

 particularly during late years, it has caused damage to the goose- 

 berries in the gardens in Jutland. Rostrup reports (R 99 a '^'^ £^ 05 b ^°') 

 an uncommonly severe attack on Ribes in the Garden of the Vet. &. 

 Agricult. College caused by the spreading of peaty earth containing 

 remnants of leaves of Carex under the bushes.
