    The present paper contributes the knowledge of wood structure of Manglie- tiastrum sinicum Law, a new monotypic genus of the family Magnoliaceae. The anatomical feature of this wood is described as follows: Diffuse-porous wood ; pores 15-25 per sq. mm, solitary or in radial multiples of 3- 4 (may be up to 6) pore cluster also occur but rare, more or less angular in shape, perforation plates scalariform, with 6-12 bors (may be up to 17), generally 7-8 or 10, intervascular pittings scalariform with fine spiral thickenings; vessel elements 748-1224, generally 876 longl wood rays heterogeneous, type IIA with 1-2, sometimes 3-4 rows of upright cells on both margins, uniserate rays 3-7 cells (may be up to 13) or 193-230u high, the multiseriate rays 3-5 cells or 68-119.2u wide, and 16-22 cells or 340-748u height; oil cells absent, fiber-tracheids 0.8-2.8 mm, generally 1.5 mm long; wood parenchma terminal, narrow banded (generally 7-8 cells wide, may be up to 12), rarely scanty paratracheal.

    The present paper is the outcome of a taxonomic study of the Chinese Buddleja in our Flora. Buddleja is one of the largest genus in the Loganiaceae. The geographical distribution of this genus is all over our Chinese territories except the northeast regions, extending from 86 to 120 of longitude and 18 to 38 of latitude. It includes 2 subgenera, 2 sections with 28 species and 6 varieties. Ten synonyms are herewith reported as new. The basic idea of classification of Marquand and Leeu wenberg is accordingly adopted, but some important alternations are made necessary for our own arrangements.

    This is paper reports the chemical constituents of f the resin from Cunninghamia unicanaliculata var. pyramidalis. On the basis of the observation made on GC and TLC, we found the resin contains more than tell components, two of them are monoterpenes (a-pinene and limonene). The other eight components were isolated from petroleum ether extract of resin. By spectroscopic data (UV, IR, NMR and GC/MS) the eight compounds were identified as α-caryophylrne (Ⅰ), P-selinenr (Ⅱ), pimara-8, 15-dinene (Ⅲ), trans-biformene (Ⅳ ), pimaradienol (Ⅴ), pimaranol (Ⅵ), trans-commuol (Ⅶ ), and trans-communic acid (Ⅷ ), respectively.

    The percentages of germination of the seeds of Gastrodia elata on different days after pollination were studied under sterile condition. The result shows that within certain period before the dehiscence of the capsule (about 1/4 of thetime required from pollination to dehiscence), the percentages of germination of different day old seeds are similar and higher than 85%.

    Dipterocarpaceae is well known as a dominant family in the tropical flora of South-East Asia, which belonged to the constituent of Paleotropic. There are 5 genera, 11 species and 1 varieties of diptrocarp native in Chinese tropicel flora and 7 genera, 16 species plantcd in Xishuangbanna Tropical Botanical Garden situated in the South of Yunnan Province were introduced from South-East Asia and other tropical regions of our country.

    The biological effects of the community structure of onr artificial rubber forest were observed with the modern instruments and the traditional microcli-mate observations. The variation regularity of some ecological factors was preliminarily discussed. It was observed that the temperature of rubber trees and the sunlight intensity at the experimental locality were closely related. In Xishuan-banna, the rubber tree temperature of facing southwest part is higher than that of facing northeast part. The highest temperature difference between W and N parts of rubber trees was 1 ℃. The temperatures of the surface and shallow parts of the rubber trees were directIy and obviously influenced by the sunlight intensity. And the influence was gradually reduced to the deeper parts of the rubber trees. The core parts of the rubber trees were indirectly influenced by the sunlight intensity.。
