After examining a large number of type and authoritative specimens of Schizophragma Siebold & Zucc., S. elliptifolium C. F. Wei and S. integrifolium var. glaucescens Rehder were reduced to synonyms of S. hypoglaucum Rehder and S. integrifolium f. cordatum S. Y. Wang was reduced to synonym of S. corylifolium Chun. Schizophragma crassum var. ellipticum J. Anthony was treated as the correct name of S. crassum var. hsitaoanum (Chun) C. F. Wei. The name S. integrifolium var. minus Rehder is reinstated. The taxonomic treatment is supported by leaf epidermal characters. 相似文献

利用光学显微镜和扫描电子显微镜对中国卫矛属(Euonymus L.)24种以及沟瓣属(Glyptopetalum Thw.)3种植物的叶表皮微形态特征进行了观察研究,测量并统计了气孔器长宽比、密度和气孔指数。结果显示,两属植物叶表皮微形态特征基本一致:叶上、下表皮细胞形状多为多边形,垂周壁平直-弓形;气孔器通常仅分布在叶下表皮;均具有无规则型气孔器,部分种还具环列型气孔器。扫描电镜下角质膜纹饰、表皮细胞界限及气孔特征在一些种间存在差异,可以作为区分部分近缘种类的参考依据。 相似文献

The anatomical structures, especially the type, distribution and arrangement of the constituent elements in the secondary phloem of Euonymus bungeanus Maxim. have been studied. The results showed that the secondary phloem was thicker, consisted of sieve-tube elements, companion ceils ,phloem parenchyma cells ,secretory ceils and rays. Sieve-tube elements, phloem parenchyma cells and secretory cells were alternately arranged in tangential bands, forming a conspicuous zone-like constitution. There was no obvious boundary between the functional phloem and the non-functional phloem. Sieve-tube elements were long, slender cells with very oblique end walls and compound sieve plates. Sieve areas on lateral wall were highly differentiated. Companion cells were triangular in transection and slender in radial section. Mostly,two or three companion cells stayed along with one sieve-tube element. In the functional phloem, phloem parenchyma cells were also slender, containing a few starch grains;but in the nonfunctional phloem they enlarged and contained abundant starch grains. Secretory cells were longer than sieve-tube elements, consisting of rubber-like material. Rays were uniseriate. Finally, the authors also discussed the phylogenetic position of E. bungeanus, which may provide some references for further study of the classification of different genera of Celastraceae. 相似文献
