THE MORPHOLOGY AND ANATOMY OF SONNERATIA LINN. f. IN CHINA

本文描述我国海南岛产的卵叶海桑、海南海桑、杯萼海桑、拟海桑、海桑等５种海桑属植物的叶、花、果实、种子、木材等的形态结构；分析它们的主要特征在各种植物之间的异同．观察结果表明，海南海桑和拟海桑两新种的形态结构特征与其它各种植物有明显的不同，并讨论它们之间的分类关系。

The present paper deals with the morphology in leaf, flower, fruit, seed and woodof 5 species of Sonneratia Linn. f. in China, which involve S. ovata Backer, S. hainanensisKo, E. Y. Chen et W. Y. Chen, S. alba J. Smith, S. paracaseolaris Ko, E. Y. Chen et W. Y.Chen and S. caseolaris (L.) Eng1. It was shown that the morphological characters of the twonew species (S. hainanensis and S. paracaseolaris) are evidently different from that of othersspecies of Sonneratia. The relationship of these species are also discussed.
