We explore these questions in Legume model system, Lotus japonicus. Compared with model plants Antirrhinum and Arabidopsis, floral pattern formation of Lotus japonicus is different in several aspects. Floral organs initiate in an order of sepals, carpel, petals, stamens. Within each whorl, organs initiate unidirectionally from ventral side to dorsal side. Initiation of organs in different whorl overlaps. Stamens exist in both 2nd whorl and 3rd whorl, and 2nd whorl is heterogeneous for the existence of different identity organs .

与模式植物金鱼草和拟南芥相比,豆科模式植物百脉根的花模式建成有其特殊性:一、花器官从腹部向背部单向起始;二、器官起始顺序是萼片—心皮—花瓣—雄蕊;三、不同轮的器官起始时间相互重叠;四、相同属性的器官出现在不同轮中;五、第二轮不均一,出现不同属性的花器官;六、花瓣和雄蕊不单独起始,而是经过了短暂的花瓣—雄蕊共同原基的阶段。

Capsule inflated, bladderlike, with membranous fruit wall, dehiscing at tip of each carpel.

膨大的蒴果,囊状,具膜质的果壁,每心皮在顶部开裂的。

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 may contain more than one carpel.

一朵花可以有一个以上的心皮。

The artificial flower doctrine that with German botanist Engele is a delegate thinks the flower of angiosperm and gymnospermous ball flower agree completely, every stamen and carpel, be equivalent to a male flower that degrades extremely and female flower respectively, consequently tentative idea angiosperm is to come from child plant hemp is yellow kind yellow Ephedra Campylopoda of curved handle hemp, following plan institute are shown, in this tentative idea, the bud of male flower piece turn into perianth, the bud of female flower piece turn into carpel, the small bud of every male flower piece after disappearing, remain a stamen only, female flower small bud piece ovule is remained only after disappearing, ministry of foundations of move unripe Yu Zi.

以德国植物学家恩格勒为代表的假花学说认为被子植物的花和裸子植物的球花完全一致,每个雄蕊和心皮,分别相当于1个极端退化的雄花和雌花,因而设想被子植物是来自棵子植物麻黄类的弯柄麻黄Ephedra campylopoda,如下图所示,在这个设想里,雄花的苞片变为花被,雌花的苞片变为心皮,每个雄花的小苞片消失后,只剩下一个雄蕊,雌花小苞片消失后只剩下胚珠,着生于子房基部。

Three separate origins of a single carpel and two separate origins of syncarpy in the subclass are also proposed. Basally connate carpel condition was the ancestral character in Alismatidae and evolved in two directions.

本文同时估计在泽泻亚纲中单心皮至少有3次独立的起源而基部合生心皮则是泽泻亚纲最原始的心皮性状。

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。

The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

观光木的花原基最初为近圆形,随着顶端分生组织的活动,花原基边缘处出现浅凹,形成第一轮花被片原基,此时,花原基呈三角形排列,后两轮花被片原基依次发生,与前一轮互生;在内轮花被片发生的后期,最初几枚雄蕊原基几乎同时出现,呈螺旋状向顶发生,最后排列成三角圆锥状;雄蕊原基发育后期,心皮原基开始发育,形状与发育初期的雄蕊原基相似,随后心皮原基进行侧向生长,在近轴面出现浅凹,进而发育为凹槽,形成腹缝线,最后腹缝线完全愈合。
