花瓣

Stamens 2 × as many as petals, whorls equal or slightly unequal in shape and length; anthers linear, lanceolate, or oblong, base tuberculate or appendaged, apex beaked, dehiscent by a single pore; connective slightly decurrent forming a spur.

雄蕊为花瓣数的2倍，各轮在外形和长度上等或稍不等；花药线形，披针形，或长圆形，基部具瘤或附属物，具喙的先端，以单孔开裂；药隔稍下延形成一距。

Petals 5-7 × 3-5 mm, obcordate, creamy white to yellowish; base of median filaments conspicuously broadened, appendaged, 0.6-1.1 mm wide; leaves pilose or rarely glabrescent; trichomes of inflorescence rachis minutely branched

花瓣 5-7 * 3-5 毫米，倒心形，乳白色的到淡黄色；中间的花丝的基部显著扩大，附属物，0.6-1.1毫米宽；叶具柔毛的或很少后脱落；花序轴的毛状体精确分开 3 H。 rockii 小叶半脊荠

Petals absent or (1--)3--5, 2-lobed, occasionally appendiculate in sinus and/or auriculate at top of claw.

花瓣无或(1-)3-5，在凹缺和/或耳形在顶端的瓣爪2裂，偶有附着。

Sepals (3--)5(--7), usually greenish, occasionally dark reddish or purple, very rarely abaxial sepal appendiculate (R. angustisepalus), deciduous or, rarely, persistent. Petals (3--)5(--10), yellow, rarely white, exceptionally red, base shortly clawed, with foveolate adaxial nectary pit which is sometimes covered by a scale. Stamens numerous or rarely few.

萼片(3-)5(-7)，通常带绿色，偶有深色带红色或紫色，花瓣(3-)5(-10)，黄，很少白色，异常红色（不在本植物区，雄蕊多数或很少很少。

Sepals, petals, and ovaries 4- or 5-merous; disk unlobed, thick; seeds arillate

萼片，花瓣和子房瓣4或5；花盘不裂，厚；种子具假种皮 7

Sepals and petals 4- or 5-merous, ovaries only 2- or 3-merous; disk lobed or nearly nonexistent; seeds typically arillate, sometimes aril absent

瓣萼片和花瓣4或5，子房只瓣2或3；花盘浅裂的或差不多不存在；种子通常具假种皮，有时无 9

Stamens (10-)15 to many, free from or connate to petals; filaments usually dilated at base; anthers 2-celled, with 2 pollen sacs per cell; connective appendages aristate, filiform or stout.

雄蕊(10-)15到多数，离生或与花瓣合生；通常的花丝膨大的在基部；花药2室，每室有2花粉囊；药隔附属物芒状，丝状或者粗。

The results are as below: 1. In Brasenia, 3 sepal primordia and 3 petal primordia initiated stimultaneously in each whorl. The first six stamen primordial initiated in a whorl stimultaneously, and the succeedings ones initiated in irregular spirals. Ascidiate carpel numerous, initiated in spirals.

结果表明： 1。莼菜的萼片和花瓣各3枚，都为轮状同时发生；雄蕊多数，除最早发生的6枚雄蕊原基为轮状同时发生外，其余均为螺旋状向心式发生；心皮多数，螺旋状向心式发生，为囊状型心皮。
