The ovary was trilocular with axile placentation and the ovule was anatropous, biteguminous and crassinucellate.

3室，中轴胎座。胚珠倒生，双珠被，厚珠心型。

The ovule is bitegminous and tenuinucellate.The archesporial cell locates under the nucellus epidermis, which develops into fuctional megasporocyte.

孢原细胞位于珠心表皮之下，直接起大孢母细胞的功能。

Simple ovary, the placentation is brink.The ovules are campylotropous.The ovule is bitegmic and crassinucellate.The megaspore archesporium is initiated from sub-epidermis of nucellus.

沙青心皮1室，边缘胎座，弯生胚珠，胚珠具双珠被、厚珠心。

Vacuoles in the synergids tended to concentrate mainly in the chalazal region.There was a peak period of lipid formation in the two synergids.

三是助细胞与珠心相接胚囊壁有些部位出现十分明显的突起，个别突起内有大型嗜锇体。

Utricles convex on both sides; rostra nearly equal to length of kernel; seed free from pericarp; leaves and bracts acicular to spinulose at apex.

胞果凸的两面；喙差不多等于珠心的长度；种离生的果皮；对具微刺的在先端针状的叶和苞片。
