In this paper the range of the following species of hepatics is treated. 10. Microlejeunea punctiformls (TAYL) SPRUCE Microlejeunea punctiformis belongs to one of the smallest hepatics and is usually found in corticolous or epiphyllous conditions in Asia. There are 89 psecimens of this species from various sources in our herbarium at present. In this paper it will be reported for the first time from Tochigi (1), Ibaraki (2), Nagano (1), Shizuoka (2), Yamaguchi (1), Kagawa (1), Tokushima (1), Kochi (4), Fukuoka (2), Saga (1), Nagasaki (2), Oita (2), Kumamoto (2), the Bonins and the Liukius. Additional new localities of the species are in municipitabity of Tokyo (1), the prefectures Hiroshima (9), Ehime (4), Miyazaki (3), Kagoshims (10), and Formosa (3). Map 10 in the text is based on 57 localities, among which 54 are new additions and 23 were previously known. From the it may be noticed that the northernmost limit of distribution of the specier is at Nikko (36°45' L.N.) in Tochigi Pref. With regard to the nature of the substrata, the results given in Table 9 were obtained from an examination of the habitats of 65 specimens. 95 (95%) specimens were collected on tree-trunks, [Table] and 3 (5%) on the living leaves of vascular plants. The macrofrequency of this species in each district is shown in Table 10,and the distribution-fall is distinct between S.W. Honshiu and M. Honshiu. [Table]
