摘要:

广义的安息香科(Styracaceae)有15个属,本文报道了其中13属93种植物的光学显微
    镜与扫描电镜的花粉形态观察结果,根据这15个属的花粉形态特征可将它们归之为三个花粉
    类型,即:安息香型,山矾型及非洲安息香型。在Wagenitz(1964)的安息香科系统中所包括
    的11个成员,正好都是属安息香型花粉的那11个属,因此他的观点可以从花粉形态方面获得
    有力的支持。将其他的四个属,即:山矾属(Symplocos),非洲安息香属(Afrostyrax),蒜味树属
    (Hua),尖药树属(Lissocarpa)从安息香科中分出的处理是合理的。狭义的安息香科有11个
    属,其中大多数属之间,在花粉形态上较难区分,这是由于安息香属的花粉形态变异幅度可以
    将其它几个属的都包括进去。因此我们认为,狭义的安息香科是一个很自然的分类群,安息香
属以外的10个属可能都是通过安息香属在进化过程中衍生而得的产物。

Abstract:

Since the establishment of the family Styracaceae by Dumortier in 1829, 15 genera have been associated with it.  Its components and circumscription were debated often and are still Waiting for evidences other than megamorphology to further clarify.  The present paper contributes the knowledge of pollen morphology for this purpose.  Pollen grains of 13 genera and 93 species in the family (sensu lato) were observed and described. Based on our own observation and data from other authors, 3 pollen types may be distinguished; viz., Styrax-type (including: Styrax, Alniphyllum, Bruinsmia, Pamphilia, Huodendron, Halesia, Pterostyrax,  Rehderodendron,  Melliodendron, Sinojackia, Parastyrax) ; Afrostyrax-type (Afrostyrax, Hua, Lissocarpa) and Symplocos-type ( Symplocos ) .
      In Wagenitz’s (1964) system of the family Styracaceae, the genera Symplocos, Afrostyrax, Hua and Lissocarpa are excluded. Its components are the remained 11 genera. It is interested enough that their pollen grains are all of the  Styraxtype.  Obviously, Wagenitz’s Styracaceae is very natural from the viewpoint of pollen morphology. Concerning the intergeneric relationships, almost all variations observed in the pollen of the
10 small styraceous genera are encountered in the large genus Styrax. The genus Styrax seems to be the stock of this family, and the others, the final products derived from it in the course of evolution.
