Hab. On leaves of Anemone cernua Thunb.

Distrib. Europe, N. America and Japan. 



REMARKS. No account concerning the occurrence of Puccinia on Anemone 

 (Pulsatilla') cernua has yet been recorded. I obtained from Mr. KASAI a specimen 

 of Puccinia on the leaf of this host. The morphological characters of the fungus 

 are as follows : 



Teleutosori amphigenous, .mostly hypophyllous, small, roundish, evenly scattered, 

 not confluent, soon naked, with the ruptured, elevated epidermis on their margin, 

 powdery, conspicuous and brown. Teleutospores oblong-obovate, oblong-ellipsoidal 

 or piriform, (both cells roundish or ellipsoidal, especially ellipsoidal in the lower 

 cell), conspicuously constricted at the septum, rounded at both ends, rarely 

 attenuated at the base, apex not thickened, densely verrucose, chestnut-brown at 

 the upper cell, lighter colour at the lower cell, 29 45 x 16 26/A; pedicels 

 short, hyaline, deciduous. 



From these characters, I am disposed to consider tins fungus to be identical 

 with Puccinia suffusca Holw. 



In 1881, ROSTRUP (12) described a species of Puccinia on Anemone of the 

 Pulsatilla type, under the name of P. Pulsatillae (Opiz), correcting OPIZ'S Dicaeoma 

 Pulsatillae. In 1884, WINTER (19) described another species of Puccinia on 

 Anemone of the Anemone type, under the name of P. fusca. In 1902, HOLW AY (5) 

 described, independently of P. Pulsatillae, a Puccinia on Anemone ( Pulsatilla), 

 giving to it the name of P. suffusca, and remarking the differences between this 

 new species and P. fusca. In 1903, BUBAK (1) pointed out clearly the morpho- 

 logical differences in the characters of the Sori and spores of P. fusca 

 and P. Pulsatillae, and he regarded P. svffusca as a synonym to P. 

 Pulsatillae. But the name of P. Pulsatillae \vas- given to a different species of 

 Puccinia on Anemone by KALCHBRENNER in 1865, hence, the name given by 

 ROSTRUP must be changed. In 1904, SYDOW in his monograph included P. suffusca 

 in P. fit-ten . II'! remarked that the differences between them are not constant as 

 BUBAK had stated, ;<nd these differences should be determined by further experi-
