1 . Uredo Rottboelliae Diet., in Engl., Bot. Jahrb., 32, 1903, (52) ; 34, 
1905, (591) ; Sacc., Syll., 17 , 1905, (457).— (PI. XII. Fig. 9). 
Hab. On Rottbcellia compressa L. v&x. japonica Hack. 
Honshü. — Prov. Musashi: Tokyo (II. June 22, 1896; II. Oct. 20, 1896. S. IIoki; II. Oct. 23, 
1899. N. Nambu ; II. Nov. 25, 1899. T. Nishida). 
Distrib. Japan. 
REMARKS. Sydow (2) suggested that this Uredo might belong to 
Puccinia Rottboellice Syd. 
In 1902, ARTHUR (3) made this species synonymous to Uromyces 
Rottboellice Arth. of Himalaya. 
In 1906, McAlpine (1) writes of the present species as synonymous 
to Puccinia cacao McAlp. of Australia, after the determination by DlETEL. 
In our country as its teleutostage is not yet known, it is still under 
question, whether our species belong to Uromyces Rottboellice , or to Puccinia 
cacao or to Puccinia Rottboellice. But one fact is certain that our species 
has no amphispores, of which Arthur (5) writes in the case of his Uromyces 
Rottboellice. In short, it seems to me safe in the present case to treat the 
present species as Uredo Rottboellice. 
2 . Uredo Kühnii (Kriig.) Wak. et Went., De Ziekten van het Suiker- 
riet op Java, 1898, (144). 
Syn. : Uromyces Kühnii Krüg., Bericht Zuck. West-Java, 1890, (117) ; 
Sacc., Syll., 11 , 1895 (182). 
Hab. On Saccharum officinarum L. 
Formosa.— Dailioku (II. Nov. 20, 1906. T. Kawakami). 
Distrib. Japan, India, Java and Australia. 
REMARKS. The present fungus was first described by KRÜGER (i) 
under the name of Uromyces Kühnii, which he had found parasitic on the 
leaves of suger cane in Java together with Cercospora Vagince Kriig. 
Later, Wakker and Went (i) proved by the infection experiments, 
that the fungus lacks entirely the teleutostage and gave it the present name.
