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。

A flower with carpels forming separate pistils, as in a buttercup..

离心皮的 Apocarpous 花中的心皮形成离生的雌蕊,如毛茛科植物。

Gynoecium of 1-5 distinct 1-loculed carpels or 2 to many partially to completely connate carpels; placentation axile ; ovules 1 to many per locule.

雌蕊群有1-5个离生1室的心皮组成,或者2到多数部分或完全合生的心皮组成;中轴胎座;胚珠1到很多每室。

A pistil composed of two or more united carpels .Having fruit or pistils with two or more carpels .

果为多心皮的,有多子房雌蕊的有带两层或更多层心皮的果实或雌蕊的

It is possible for the unicarpellate condition to have been directly derived by reduction from syncarpy, and it could also be that the unicarpellate state has been derived from apocarpy by reduction in carpel number. The present results indicate that a progression has occurred in the evolution of carpels in Alismatidae from basally connate carpels through syncarpy or apocarpy to a single carpel.

本研究揭示了泽泻亚纲中不同心皮之间可能的演化过程,即从基部合生心皮向合生心皮或离生心皮方向演化,而单心皮,则很有可能是通过具多数、合生的心皮直接简化而来;同时它也有可能从具多数、离生的心皮简化而来。

Ovary superior, disk absent, locules and carpels 3-5 or more; placentation axile; ovules anatropous with a single integument, 10 or more per locule; styles as many as carpels, distinct or connate, generally persistent.

子房上位,无花盘,室和心皮3-5或更多;中轴胎座胚珠倒生,有单个珠被,每子房室有10个或更多的胚珠;花柱和心皮同数,离生或者合生,通常宿存。

Leaves odd-pinnately 3- to many foliolate or sometimes digitately 3-foliolate (occasional leaves even-pinnate, 2-foliolate, or 1-foliolate); functional gynoecium 1-5-loculed, with distinct carpels or carpels basally connate; fruit of 1-5 distinct or basal

叶奇数羽状复叶3-对具小叶的很多或有时具3小叶偶然偶数羽状复叶,2具小叶,或单身复叶;功能的雌蕊群1-5室,具离生的心皮或心皮基部合生; 1-5离生或者基部的果 1 Zanthoxylum 花椒属

Fruit drupaceous, of separating mericarps or ± completely syncarpous, drying brown to black or rarely pale gray-brown when ripe; abortive carpels, if any, persistent; outer pericarp ± fleshy; endocarp bony next to locule, otherwise woody, in mericarps developed from 2-ovuled carpels forming a median longitudinal partial partition within locule.

果核果状,有分离的分果瓣或者多少完全的合心皮,成熟后变干,棕色或黑色,很少灰棕色;败育心皮,如果有的话,宿存;外部果皮多少肉质;内果皮骨质或木质,在分果瓣里内果皮由2胚珠的心皮在每室内形成中间的分隔。

Five floral organ identity genes of Mussaenda pubescens were cloned and their expression patterns among different organs were detected by RT-PCR. The AP1 homologue, MupAP1, is expressed in enlarged and small sepals, petals and stamens, carpels and fruits; the SEP3 homologue, MupSEP is strongly expressed in all floral organs and weak in leaves as well. Two of the B class gene, AP3 homologue MupDEF and TM6 homologue MupTM6, were detected expressed in all floral organs, however, the other B class gene, MupGLO, homologous to PI, were detected expressed in small sepals, petals and stamens, carpels and fruits, but not in enlarged sepals.

本论文选殖出五个毛玉叶金花花器同源基因,其中A群基因AP1的同源基因MupAP1在两型花萼、花瓣及雄蕊、心皮、果实中有表现,E群基因SEP3的同源基因MupSEP则在所测部位均有表现,B群基因中,AP3的同源基因MupDEF及TM6的同源基因MupTM6在两型花萼、花瓣及雄蕊、心皮及果实中均有表现,另一个B群基因,PI的同源基因MupGLO则在花瓣及雄蕊、心皮、果实及小花萼中有表现,但在膨大花萼中并没有侦测到表现。

Where other carpels to give a multilocular ovary, the marginal placentae of the carpels may fuse in the center of the ovary,giving axile placentation, as in tulip(Tulipa spp.).

某些心皮形成多室子房,心皮的边缘胎座可能在子房中央融合形成中轴胎座,如在郁金香中。
