| 知多一點點：木賊屬的孢子大多是無性孢子，但問荊較小的孢子則可以產生出雄性的原葉體。孢子含有四個彈絲，有如濕度感應彈簧般地作用著，讓孢子只會在孢子體已縱向地裂開後才開始傳播。 |
More to learn: Horsetails are mostly homosporous, though in the field horsetail smaller spores give rise to male prothalli. The spores have four elaters that act as moisture-sensitive springs, assisting spore dispersal through crawling and hopping motions after the sporangia have split open longitudinally.[7] |
