雌蕊叶

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

With American botanist cypress apply reach Halier, the really beautiful doctrine that British botanist breaths out Qin Song to be a delegate thinks the flower of angiosperm is come by evolution of ball of leaf of primitive gymnospermous bisexual spore, consequently tentative idea angiosperm is the Benneisu that in coming from gymnosperm, eradicates already iron eye, draft Su Tie especially , the bud on ball of its spore leaf piece evolve for perianth, sporule leaf evolves for stamen, big spore leaf evolves for pistil , axis of ball of its spore leaf shortens for rachis.

以美国植物学家柏施及哈利尔，英国植物学家哈钦松为代表的真花学说认为被子植物的花是由原始裸子植物两性孢子叶球演化而来，因而设想被子植物是来自裸子植物中早已灭绝的本内苏铁目，非凡是拟苏铁，其孢子叶球上的苞片演变为花被，小孢子叶演变为雄蕊，大孢子叶演变为雌蕊，其孢子叶球轴则缩短为花轴。
