The following results were obtaind. 1. Yaeyamashitan in Hirakubo was designated as a national treasure in May 15,1972. 2. Growth of 78 spontaneous trees and cultivars was confirmed on Ishigaki Island. 3. In Hirakubo, in addition to 2 trees as a national treasure, 1 tree (diameter at breast height, 20cm; tree height, 11.5m) and 1 young growth (diameter at breast height, 13cm; tree height, 8m) were confirmed in July, 1991 and December 1994,respectively. 4. Though the number of seeds per legume had been considered to be 1,1\u0026acd;4 seeds per legume were observed. 5. One seed/legume was observed in 43% of 365 legumes, 2 seeds/legume in 39%, 3 in 17%, and 4 in 1% the incidence of 1 seed/legume was the highest. 6. Germination of seeds occurred 2\u0026acd;7 days after seedling in 1 seed legumes, and maximum germination of 3 seeds each was observed 4 days and 6 days after seedling. 7. Of the trees as a national treasure, 1 showed cuts in the trunk and root, and the other showed cuts in the root. This damage was deep, and each cut surface was decayed. Restoration of the damage parts is urgently necessary. 8. The forest stand is considered a Pterocarpus indicus community of Diospyros maritima-Psychouia manilensis alliance in the lowland vegetation.
