梾木属的一新亚属——华茱萸亚属

Cornus L. s. 1. is a large polytypic genus. The classificantion of which has been so different that some authors recognize several separate genera, while others treat them as ei- ther subgenera or sections.  New evidence from many disciplines such as palynology, cyto- logy, wood anatomy and embryology supports the view that the genus should remain in the broad sense.  I basically agree with the treatment by Ferguson (1966b) before my finishing a comprehensive study on Cornus L. s. 1. except for supporting  the separation  of subgenus Afrocrania as an independent genus.  A new subgenus Sinocornus Q. Y. Xiang, containing one species, C. chinensis Wangerin, is established here on account of its inflorescence axillary and different from the other members of the genus which all have terminal inflorescences only. The inflorescence developed from a terminal bud implicates the sympodial nature of axis of stem and the one from an axillary bud the monopodial one.   It is reasonable to regard the character as of subgeneric value.  Also a new combination, Cornus subgen. Syncarpea (Na- kai) Q. Y. Xiang, is proposed here as a substitute for Cornus subgen.  Benthamia (C. B. Clar- ke) Schneider used for a long time.  Because the valid publication of the former name subgen. Syncarpea Nakai is earlier than the latter one.  The types of inflorescences of 8 subgenera re- presented by type or selected species are illustrated.     

试析“不X不Y”格式

本文从描写语言事实入手，按“小三角”的研究思路，从结构成分，语义类型，语用价值三个角度对“不X不Y”结构，作了较全面的考察，从结构成分来看，能够嵌入“不X不Y”结构的“X、Y”一般是单音节，也有双音节乃至多音节，“不X不Y”结构构成两个停顿，两个停顿前后之前表并列，表因果或表假设关系。
