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 structure which appears to be simple, though actually derived from the fusion of separate structures, as a pistil which appears to be composed of a single carpel, though actually composed of two or more carpels.
假单基数的 Pseudomonomerous 实由离生结构愈合而成却看似单一的结构,如看似单心皮的雌蕊,实为两个或多个心皮组成。

The developmental process of W. delavayi indicated that the syncarpous and uniloculate gynoecium was in fact bicarpellate, which consisted of a fertile carpel and a sterile one. It was pseudomonomerous.
根据对雌蕊群的发生和发育过程观察,该种的子房是由一个近轴面的可育心皮和一个远轴面的不育心皮融合而成的单室子房,为假单心皮雌蕊。
-
Botany A dry, single-chambered fruit that splits along only one seam to release its seeds, as in larkspur and milkweed.
骨突:干燥、单心皮的果实,仅沿着一个生出种子的合缝裂开,如飞燕草和马利筋
-
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。

Fruit 1-5 drupelike or nutlike monocarps produced per flower.
果为1-5个核果状或者坚果状的单心皮果。

carpel:心皮
构成雌蕊的单位称为心皮(carpel),是具生殖作用的变态叶. 有些植物,一朵花中的雌蕊只是由一个心皮所构成,称为单雌蕊(simple pistil),如蚕豆、大豆. 更多种类植物的雌蕊是由几个心皮构成的,其中有的各心皮各自分离. 因而各雌蕊也彼此分离,
