1.常山是八仙花科植物黄常山Dichroa.febrifiuga Lour.的地下部分,而蜀漆是本植物的带叶枝梢,两者都有抗疟的效力。2.木文简单地介绍了前人研究常山的情况,然後详细地描述了,常出和蜀漆的性状和组织构造;并指出了某些组织特徵在分类学上的意义。3.常山的重要特徵是:(1)导管,末梢壁长而斜置,有显著的梯纹穿孔,并常含有侵填体;(2)分隔木纤维;(3)含草酸钙针晶束的异细胞,针晶束外有粘液包围;(4)厚壁的中柱梢纤维;(5)内生性的木栓层。根茎和茎的根部周围有显着的根鞘,根鞘由厚壁的木化细胞所成,壁上有单纹孔。 4.蜀漆的重要特征是:(1)厚壁有疣的单细胞毛;(2)平轴式气孔;(3)垂周壁上具有纹孔的表皮细胞;(4)叶绿锯齿上的水孔;(5)含草酸钙针晶束的异细胞,针晶束外有粘液包围;(6)脂肪油珠,存在於大多数叶肉细胞中。此外、并有由茎中来的厚壁的中柱鞘纤维和内生性的木栓层,以及特殊的梯纹导管,其形状和在地下器官部分所见的一样。
1. Changshan is the underground part of Huang Chin-shan Dichroa. febrifiuga Lour. of the hydrangea family, and lacquer is the leaf shoot of this plant, both of which have antimalarial efficacy. 2. The essay briefly introduces the situation of Changshan in previous studies, and then describes in detail the traits and organizational structure of the lacquer and lacquer. It also points out the significance of some tissue features in taxonomy. 3. The important features of Changshan are: (1) Catheters, long and oblique walls of the distal wall, prominent perforation of the tread pattern, and often contain invasion bodies; (2) Separation of wood fibers; (3) Needles of calcium oxalate crystals Of the different cells, surrounded by mucus surrounded by the needle beam; (4) thick-walled mid-tip fibers; (5) endophytic cork layer. There are prominent root sheaths around the roots of the rhizomes and stems, and the root sheaths are made of thick-walled woody cells with single pits in the walls. 4. The important features of lacquer are: (1) thick-walled unicellular hairs; (2) flat-shaft pores; (3) epidermal cells with pits in the peristomal wall; (4) serrated leaves Water hole; (5) Different cells containing calcium oxalate needles, surrounded by mucus surrounding the needle bundle; (6) Fat oil beads present in most mesophyll cells. In addition, there are thick-walled pleural fibers and endogenous cork layers coming from the stem, as well as special ladder catheters, the shape of which is the same as that seen in the underground organs.
