Introduction

Apparently the first record of the rust fungi which parasitize grasses from the southern part of the main island of Kyusyu, was made 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 Mc Alpine, P. graminis Pers. and P. lolii Niessl = P. coronata Corda) from Kagosima Prefecture, the southern Kyusyu. In 1952, Naohide Hiratsuka (21) recorded one species of Stereostrat~tm, five of Uro­ myces, 12' of Puccinia and one of Uredo parasitic on grasses from Miyazaki and Kagosima Prefectures. The first account of species of rust fungi which parasitize grasses from the Ryukyu Islands, including the Satunan IsIs. (Tanegasima lsI. and Yakusima lsI.) and the Amami IsIs., ~as that of Puccinia levig~ta (Syd. et Butt) Hiratsuka, f. by Seiya Ito (31), in 1909. He recorded Puccinia levigata (Syd. et Butl.) Hirats.uka., f. on leaves of Oplismenus compositus Beauv. based upon specimens which were collected 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 Naohide Hilllatsuka (18~20) one species of Puccinia in 1938, one of Angiopsora, three of Uromyces and 14 of Puccinia in 1940, and five of Puccinia and two 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 species of 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 fungi parasitic on the grasses collected in the southern Kyfisyfi (Miyazaki and Kagosima Prefectures) and the Ryukyu Islands, including the Satunan 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 include besides a number of collectibns made by Naoharu and Naohide Hira­ tsuka, Shun-ichi Shimabukuro, Yoshihisa Taira, Shoji Sato, Yasuji Morimoto, 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 Prefecture in October 1956, and in Okinawa Island, the Ryukyu Islands in January 1957. The total number of specimens examined amounts to more than eight hundred, amongst which are included 55 species. The following table shows the number of species, by genera, hitherto known from the southern Kyfisyfi and the Ryukyu Islands, and the total.

As shown in the above table, the rust fungi which parasitize grasses found in the southern districts of the main island of Kyiisyo. 26 T. HIRATSUKA 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 the present work was executed, for their useful suggestions and criticism. The writer also wishes to express her sincere thanks to Prof. Shun-ichi Shimabukuro (University of the Ryukyus) and Mr. Shoji Sato (Faculty of Agriculture, Tokyo University of Education), who made many valuable suggestions. She is also indebted to Dr. Jisaburo Ohwi of the National Science Museum (Tokyo) for identification of host plants of the fungi, and to Miss Eiko Sakai for her faithful assistance on the present investigations. The present work has been partially supported by a Grant in Aid for Developmental Research of the Department of Education (1955­ 56. no. 21016), to the directors of which the writer wishes to take this opportunity of extending her sincere thanks. The specimens studied are all kept in the Hiratsuka Herbarium, Tokyo, Japan. Rust Fungi on Grasses Collected in Southern Kyusyu & Ryukyu IsIs. 27

The present fungus is the tropical or southern species, and it is 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 found parasitic on the leaves of Saccha1"um ojficinarum in Java. In 1914, its teleutosorial stage was first described by Butler, based upon a specimen 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 from the Ryukyu Islands bear the uredosorial stage only. But, the writer found a specimen of the teleutosori on Saccha1"um ojficinarum froni Formosa among the Mycological Collection, deposited in the Herbari­ um of the National Science Museum (Veno, Tokyo)_ That collection was 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.

DISTRIBUTION. World wide. The oldest valid name of the leaf rust or brown rust fungus complex of small grains and grasses is Puccinia recondita Roberge ex Desm. described on Secale cereale L. in 1857, thus antedating Puccinia rubigo-vera Winter of 1882. Puccinia recondita is a common rust of wheat and rye in Japan. In literature, it is usual to find this rust of wheat under Puccinia triticina, and of rye under Puccinia dispersa, both are merely biologic forms or varieties of Puccinia recondita.

Geographical distribution

It is an interesting matter to compare the flora of the grass rusts of the southern Kyftsyft with that of the Ryukyu Islands, and the flora of the rusts of the southern Kyusyu and the Ryukyu Islands with that of other regions in the world and to consider their relations. Before the writer goes further in the discussion of the subject, it is necessary to show the distribution of each species in .different regions of the southern Kyftsyft and the Ryukyu Islands, as shown in Table 2. Such species are distributed in other regions of the world, as shown in Table 3.

1. Number of genera and species in the southern KytisyU and the Ryukyu Islands. From Table 2, it will be noted that the l1umber of genera is 5, the species totalling 55. They are: Phakopsora 1 species, Dasturella 1 species, Stereostratum 1 species, U'romyces 6 species, Puccinia 45 species and Uredo 1 species. The number of genera and species in the southern Kyftsyu and the Ryukyu Islands is shown in Table 4, and those in the northern and southern districts of the Ryukyu Islands in Table 5.

The first detection to be made from Table 6 is the comparatively close relationship between the species of the southern Kyftsyft and the Ryukyu Islands and those of China and India (80 %). Secondly, the table shows that Formosa (69%), Northern and Middle Kyusyft (67 %), Honsyft (67 %), Shikoku (64%), and Philippines and Malaysia (45 %), each possesses more than 45 % of the species represented in the southern Kyftsyft and the Ryukyu Islands.

3. The southern or tropical species in southern KytisyU and the Ryukyu Islands. The flora of rust fungi parasitic on the grasses in the southern Kyftsyft and the Ryukyu Islands is largely dominated by species of the southern or tropical origin. The southern or tropical species in the southern Kyusyft and the Ryukyu Islands are as follows:- ( 1) Phakopsora incompleta (Syd.) Cummins. 92 T. HIRATSUKA

南九州お よび琉球列 島所産のイネ科植物に寄生する鏡菌 (摘要)

平 塚 利 子

1. 本論文は南九州および琉球列島所産のイネ科植物に寄生する銃歯の分類学的ならびに地 理学的研究の成果である｡ 2. 本研究における調査地域は,南九州の鹿児島,宮嶋両県および琉球列島の薩南群島,奄美 群島,沖縄群島,宮古および八重山群島である｡ 3. この地域内で採集 した標本は 800 点以上に達する｡これ らの標本をもとにして,確認 したイネ科植物に寄生する鋳菌の種類数は Melampsoraceae に属する Phakop80r a 属 1 種, D asturella 属 1 種, Pucciniaceae に属する StereoStratum 属 1 種, UromyceS 属 6 観, Puc oinia属 45 種,および Uredinale8Im.perfecti に属する Uredo 属 1 種,総計 6 属 55 種 である｡これらの属の うち Puo oinia属に属する種類が 45 種で最 も多く,つぎが Uronyoes 属の 6 租である｡これ らの種類すべてについて,その形態的性質を記載 し,その地理的分布を 示 し,既往の同地域内における記録 をあげ,さらに主なる異名を示 した｡ 4. 南九州および琉球列島所産種類総数 55 種に対する南九州の種類数および琉球列島の種 類数の割合はそれぞれ 80% および 75% である｡ 5. 南九州および琉球列島に塵する種類 と典通観の一世界各地域における分布状態は,本地域 に塵する55 種に対 して最 も共通種が多いのは中華大陸および インド地域に塵する44 位 (80%) である｡ 6. 南九州および琉球列島所産租類総数 55 租の うち,南方系の種類は, Phakopsora 属 1 位, D asture lla 属 1 穂, UronyoeS 属 2 位, Puc oinia属 23 種,および Uredo 属 1 種,計 5 属, 28 種である｡ 所産種類総数 55 種に対する北部琉球列島および南部琉球列島の割合は,いずれ も56% ,南九州が 37% となり,琉球列島が南九州 よりも著 しく多いが琉球列島の南部および 北部地域ではほ とんど大差がない｡ 7･ 今回,新 しく加 った榎頬は,つぎの如 くである｡

1) 新 種: Puo oini aa rund inis -do nacis T.HiratSuka-A r undodo nax( ダ ンチク) に寄生. 2) 南九州のフロラに新に加 った種: (1) Phakop80r a incomplet a (Syd.)Cummin 8, (2)Uronycesooronatus MiyabeetNi8hida , (3) Puc oiniad iplaohnicola Dietel ,
