摘要
自《槐属的研究》一文发表后,作者对本属植物的地理分布特点、主要形态特征和某些化学物质的演化趋势及其与临近属的相互关系等作了综合分析研究。结果表明:本属植物的演化趋势是由乔木→灌木或亚灌木→草本;羽状复叶→近掌状复叶或单叶;托叶有逐步退化趋势,小托叶有→无;顶生圆锥花序→多种着生的总状花序;花萼裂片连合程度逐步增加,小苞片有→无;荚果果皮构造及质地也呈进行性退化趋势,即果皮从三层完整果皮向二层过渡,质地肉质→木质→革质或近革质,开裂方式由不开裂→豆科典型的二瓣开裂→本属特有的四瓣开裂。金雀花碱在本属植物中出现较早,在肉果亚属已有较多种类含有此碱,并随着植物的进化而含有种类在逐步减少,而苦参碱在本属植物中出现的较晚,肉果亚属的植物只有少数种类含有此碱,裂果亚属含此碱的种类较多,并随着植物的进化而含有种类在逐步减少。据此,作者提出了本属植物的系统树,并对本属各分类群的系统位置作了全面修订与补充。
After publication of the study on the genus Sophora, author makes the systematic study on the parts of the geographical distribution,a variational trend of main morphylogical characteristic and some chemical matters in the genus Sophora, and the relationship with near genera once again. Results shewed trend of evalution on Sophora plants was: tree to shrub or subshrub to herb, pinnately compounds leaves to unifolialate leaves, stipelate to instipelate, panicle to raceme, a connection of calyx has been increasing gradually, bracteolate to bractless, legume carpodermis is carnous or subcarnous to ligniferous to lethery, indehiscence to bivalve dehiscence to tetravalves dehiscence, For the above reason, we proposed the Sophora systematic tree, and revied systematic position of all taxa,
