S. ITO. 
Hab. On Melica nutans L. 
Hokkaido. — Prov. Ishikari : [ozankei (II. Aug. 22, 1898. K. Miyabe; II. Aug. 24, 1898. T. 
Nishida); Yamahana (II. Sept. 15, 1007. S. Irr.) ; Maruyama (IT. Sept. 22, 1907. S. Ito). 
Distrib. Japan. 
Remarks. Compared with Puccinia Melicce of Europe, our species 
resembles it very closely in the remarkably small size of their uredospores. 
But they differ from each other in the fact that in our species there are 
yellow-ochre colored clavate paraphyses, although few in number, while 
ERIKSSON particularly laid stress on the absence of paraphyses in the sori 
of Puccinia Melicce. 
5 . Uredo Bromi pauciflorae S. Ito. n. sp. — (PI. XII. Fig. 13). 
Uredosori, epiphyllous ; minute, oblong or sublinear, scattered or 
gregarious, often confluent, naked, with ruptured epidermis, pulverulent, 
brownish yellow. Uredospores, globose or broadly ellipsoidal, echinulate, 
yellow or brownish yellow, 20-32 x 20-28/2 ; epispore thin ; germ-pores 6-8 
(rarely 10) ; paraphyses numerous, clavate, hyaline, apex not thickened, 
44-86 x 14-22/2. 
Hab. On Brovins pauciflorus Hack. 
Hokkaido.— Prov. Oshima: Kamiiso (II. July 12, 1890. K. Miyabe). 
Remarks. Although there are many species of Puccinia known to be 
parasitic on Brovins, yet Puccinia coronata is the only species that has the 
paraphyses in the uredosori. While our species has numerous germ-pores, 
Puccinia coronata only 3 or 4. Moreover, the shape of their paraphyses are 
quite different. 
The present species seems to agree Puccinia gibberosa on Festuca which 
is closely related in its systematic position to Brovins. 
6 . Uredo Polliniae-imberbis S. Ito. n. sp. — (PI. XII. Fig. 11). 
Uredosori, hypophyllous ; minute, roundish or oblong, on brownish 
spots, scattered or gregarious, sometimes confluent, naked, pulverulent, in- 
conspicuous, orange-colored. Uredospores, globose, subglobose or piriform, 
densely echinulate, yellow or yellowish-brown, 20-26x16-24/2; epispore 
thin; germ-pores 5-9, rarely 11, scattered irregularly; peraphyses numerous,
