Introduction

Apparently the first record of the rust fungi which parasitizegrasses from the southern part of the main island of Kyusyu, wasmade by Naohide Hiratsuka (17) in 1936. In his paper, entitled,"Uredinales collected in Kiushu. III." (1936), there have been record-ed two species of Uro1nyces (Uromyces halstedii De Toni and U.linearis Berk. et Br.) and three of Puccinia (Puccinia cacao McAlpine, P. graminis Pers. and P. lolii Niessl = P. coronata Corda)from Kagosima Prefecture, the southern Kyusyu. In 1952, NaohideHiratsuka (21) recorded one species of Stereostrat~tm, five of Uro-myces, 12' of Puccinia and one of Uredo parasitic on grasses fromMiyazaki and Kagosima Prefectures.

The first account of species of rust fungi which parasitize grassesfrom the Ryukyu Islands, including the Satunan IsIs. (TanegasimalsI. and Yakusima lsI.) and the Amami IsIs., ~as that of Puccinialevig~ta (Syd. et Butt) Hiratsuka, f. by Seiya Ito (31), in 1909. Herecorded Puccinia levigata (Syd. et Butl.) Hirats.uka., f. on leaves ofOplismenus compositus Beauv. based upon specimens which werecollected by Naoharu Hiratsuka at Syuri (Naha-si) in Okinawa Island,as Diorchidium levigatum Syd. et But!.

Rust Fungi on Gl'asses Collected in Southern Kyusyfi & Ryukyu IsIs. 25

Up to 1941 since that time, there have been recorded by NaohideHilllatsuka (18~20) one species of Puccinia in 1938, one of Angiopsora,three of Uromyces and 14 of Puccinia in 1940, and five of Puccinia andtwo of Uredo in 1941 from the Ryukyus. Since 1953, Naohide Hira-tsuka and his collaborators (24~30) have studied actively on the rust-flora of the Ryukyu Islands, and there have been recorded one speciesof Ph.akopsora, one of Dasturella, four of Urom.yces and 28 of Puccinia,which parasitize grasses from the Ryukyu Islands, in 1955 to 1957.

In this article, now, are enumerated the species of rust fungiparasitic on the grasses collected in the southern Kyfisyfi (Miyazakiand Kagosima Prefectures) and the Ryukyu Islands, including theSatunan IsIs., the Tokara IsIs. and the Amami IsIs., and their taxo-nomic account and geographical distribution are presented.

The materials used by the writer in the present work includebesides a number of collectibns made by Naoharu and Naohide Hira-tsuka, Shun-ichi Shimabukuro, Yoshihisa Taira, Shoji Sato, YasujiMorimoto, Nobuhide Hirai, Shoichi Hirata, Shigetaka Katsuki, Yasu-yuki Hiratsuka and others, deposited in the Hiratsuka Herbarium,the specimens collected by the writer herself in Kagosima Prefecturein October 1956, and in Okinawa Island, the Ryukyu Islands inJanuary 1957. The total number of specimens examined amounts tomore than eight hundred, amongst which are included 55 species.The following table shows the number of species, by genera, hithertoknown from the southern Kyfisyfi and the Ryukyu Islands, and thetotal.

and the Ryukyu Islands are 55 species in total. Among all the genera,the largest is the Puccinia having 45 species, next comes the Uromyces.

It is a pleasure for the writer to express her appreciation to Prof.Hirosi Ito and Prof. Naohide Hiratsuka, under whose direction thepresent work was executed, for their useful suggestions and criticism.The writer also wishes to express her sincere thanks to Prof. Shun-ichiShimabukuro (University of the Ryukyus) and Mr. Shoji Sato(Faculty of Agriculture, Tokyo University of Education), who mademany valuable suggestions. She is also indebted to Dr. Jisaburo Ohwiof the National Science Museum (Tokyo) for identification of hostplants of the fungi, and to Miss Eiko Sakai for her faithful assistanceon the present investigations.

The present work has been partially supported by a Grant in Aidfor Developmental Research of the Department of Education (1955-56. no. 21016), to the directors of which the writer wishes to takethis opportunity of extending her sincere thanks.

The specimens studied are all kept in the Hiratsuka Herbarium,Tokyo, Japan.

The present fungus is the tropical or southern species, and itis widely distributed the subtropical and tropical regions.

The uredosorial stage of this fungus was first described by Kruger(1890) under the name of Uro'myces kuehnii, which he has foundparasitic on the leaves of Saccha1"um ojficinarum in Java. In 1914,its teleutosorial stage was first described by Butler, based upon aspecimen which was collected by him at Bassein, Burma on Sac-charum spontaneum, and it was treated by him as a species of Puc-cinia, naming Puccinia kuehnii.

The above mentioned two specimens of the present species fromthe Ryukyu Islands bear the uredosorial stage only. But, the writerfound a specimen of the teleutosori on Saccha1"um ojficinarum froniFormosa among the Mycological Collection, deposited in the Herbari-um of the National Science Museum (Veno, Tokyo)_ That collectionwas made by'Mr. T. Takamure at Sinsya-syo, prove Taichfi, Formosa,and it is the only one of its teleutosoriaI stage in the Japanese Archi-pelago.
