Abstract: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.
