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。

Ovary surrounded by a coronary disk, partly inferior, becoming inferior in fruit, 2-loculed; ovules anatropous, pendulous, 1 per locule, 1 ovule undeveloped after anthesis; placentation axile.

子房被一个冠状的花盘包围，不完全下位，在果期完全下位，2室；胚珠倒生，下垂，每室1，1胚珠在花后不发育；中轴胎座柱头头状，落叶。

The quantities of starch grains in the two"cells"in micropyle part of embryosac gradually decrease and become unclear.With the further development of embryosac the starch grains in the central cell and antipodal cell disappear in succession,however,the egg cell does not.

在准极核移向胚囊中部前后，不同的功能性细胞有不同的表现，珠孔端的两个&细胞&淀粉粒数量逐渐减少并变得不明显，随着胚囊的进一步发育，其中中央细胞和反足细胞内的淀粉粒相继消失，但卵细胞内却一直保存着。

Past study re-sults had indicated that MMC in the apomictic type could at most develop to te-trad stage.We observed that the sexual embryo sac of"Pingyi Tiancha"coulddevelop into 4-nuclei embry sac.

前人只观察到无融合生殖类型的大孢子母细胞至多能发育到四分体时期，而我们观察到平邑甜茶的有性胚囊能发育到四核胚囊。

To understand the degeneration of unfertilized aposporous embryo sac in an aposporous species Pennisetum squamulatum, the central cell in the unfertilized embryo sac was characterized ultrastructurally.

为理解植物无孢子生殖胚囊未受精条件下的退化，对无孢子生殖植物非洲狼尾草未受精成熟胚囊中央细胞退化做了细胞形态学研究。

Ovary 2-locular, carpels free at apex; ovules mostly 1 per carpel, less often many, but then most of them sterile, crassinucellar, bitegmic, anatropous, halfway between apotropous and epitropous, pendent from ovary top if solitary, along the carpellary margins if numerous; placentation axile.

子房2室，心皮离生在先端；每心皮多数的胚珠1，较少的通常很多，中途在apotropous和胚珠向上转之间，然而他们中大多数不育，crassinucellar，bitegmic，倒生，中轴胎座花柱和柱头2。

Seeds globose, ovoid, or fusiform, small, sometimes appendaged; appendage caudate; embryo straight, minute, enclosed by fleshy endosperm.

种子球状，卵球形，或者纺锤形，小，有时有附属物；附属物有尾尖；胚直，小，被肉质的胚乳包围。

Thpetum is the gland cell type. The pistil has two carpels, the ovules belong to straight ovules with bitegmic;77% nucellus stoped development before from the archesporial cell and disappear and 23% nucellus atrophy .so the flower cannot grow seeds.

安祖花的雌蕊是由2 心皮组成，胚珠为直生胚珠，双珠被，77%珠心细胞在胞原细胞形成之前停止发育，并且逐渐解体消失，23%珠心细胞发生萎缩，导致雌蕊败育。

Seeds not arillate, with usually large embryos and abundant endosperm.

种子不具假种皮，通常有大的胚和丰富的胚乳。

Seeds globose-ovoid, arillate or not, usually smooth; endosperm abundant; embryo straight; cotyledons rather thick, plano-convex.

种子球状卵圆形，具假种皮与否，通常平滑；胚乳丰富；胚直立；子叶相当厚，平凸。
