目的:对铁轴草进行鉴别研究。方法:采用性状与显微鉴别的方法。结果:铁轴草茎密被锈色柔毛;叶红棕色,叶面密被锈色柔毛,叶密被白色柔毛,根横切面皮层较宽,木质部导管大而多;茎横切面韧皮部较狭窄,外侧有断续排列成环的纤维束,棱角处较密。非腺毛众多,不分枝和分枝的均有,腺毛也有短柄和长柄两种,非腺毛和腺毛均个别细胞缢缩。结论:以上特征可作为铁轴草的主要鉴别依据。 Objective: To study the identification of Trifolium repens. Methods: The method of character and microscopic identification was used. RESULTS: The stems of the stem were densely rust-colored; the leaves were red-brown, the leaves were densely rust-colored pilose, the leaves were densely covered with white pilose, and the roots were transversely sectioned with a wide cortex; the xylem vessels were large and numerous; the stems were transversely sectioned and phloem. It is narrow, and there are intermittently arranged fiber bundles on the outside, and the corners are dense. There are many non-glandular hairs, both unbranched and branched. Glandular glandular hairs also have both short and long stalks, and individual glandular hairs and glandular hairs are contracted by individual cells. Conclusion: The above characteristics can be used as the main identification basis for the iron grass.
