Abstract
We attempted to count type materials and taxa of vascular plant collections in Kanagawa Prefectural Museum of Natural History, in order to make them useful for future researches, and analyzed their configurations based on specimen attributes such as localities of prefectures, collection years, and collectors. As a result, 183 type materials including 46 holotypes are deposited in the museum. We calculated the ratio of the taxa in the museum to those recorded in all Japan and prefectures, only by the number without considering the compositions types. The museum holds vascular plant specimens of 89.4 % for the whole country of Japan, and of 95.4 % for Kanagawa Prefecture with the largest collection. The composition of prefectural collections with a large number of specimens is due to the contribution by Mr. Tatsuyuki Ohba, Mr. Miyoshi Furuse, and Mr. Hideo Takahashi. The number of specimens is also larger in Shizuoka and Chiba prefectures, resulting from other collector and specific flora investigations.
