From Seram Island, Indonesia
Journ. Hattori Bot. Lab. No. 63 : 421-424 (Dec. 1987) A NEW SPECIES OF LEPIDOZIA (HEPATICAE) FROM SERAM ISLAND, INDONESIA HIROSHI DOEl! Very recently, I reported ten species of Lepidozia (Lepidoziaceae) from Seram Island, Indonesia, on the basis of a collection made by the botanical expeditions to Central Moluccas of the University of Tokyo and Herbarium Bogoriense (Doei 1987). In the collection, I found a distinctive new species of Lepidozia. The species is best characterized by the filiform plants as well as by the unlobed and long triangular leaves. As the species was recorded as nomen nudum in that paper, I will formally describe it below. I wish to express my cordial thanks to Prof. M. Tamura of Kobe University for his kind advice and encouragement throughout the present study. Thanks are also due to Mr. H. Akiyama of Kyoto University who kindly afforded me an opportunity to study his interesting collection and to Prof. N . Kitagawa of Nara University of Educa tion who gave me valuable suggestions and critical advice.
