Petals alternisepalous,(2-)4, absent in female flowers of some Myriophyllum , imbricate, longer than sepals, often deciduous with stamens.

花瓣与萼片互生，(2-)4，但是Myriophyllum的一些种类雌花无花瓣，花瓣覆瓦状排列，比萼片长，通常与雄蕊一起脱落。

Ovary inferior, with as many carpels and locules as sepals, septa sometimes thin or absent at maturity; placentation axile or parietal, ovules 1 to many per locule, in 1 or several rows or clustered, anatropous, bitegmic; style 1; stigma with as many lobes as sepals or clavate to globose.

子房下位，子房室、心皮与萼片同数，在成熟时隔膜有时薄或无；中轴胎座或侧膜胎座，每室胚珠1到多，排成1或几列或丛生，倒生，具双珠被；花柱1；柱头裂片与萼片同数或棍棒状到球状。

Sepals and petals 5, persistent after anthesis, sepals free, entire or rarely glandular-ciliate, petals entire or glandular-ciliate, apiculus absent.

萼片和花瓣5，宿存在花后，萼片离生，全缘或很少具腺具缘毛的，花瓣全缘或具腺具缘毛，细尖无。

Sepals 4. Petals absent. Stamens 4, opposite sepals; anthers basifixed.

萼片4。花瓣无；雄蕊4，与萼片对生；花药基着。

Mm. Male flowers: pedicels filamentous, 3-5 mm; calyx red or purple; sepals 6, biseriate, subequal, obovate, 2-3 × ca. 1.5 mm; disk segments 6, opposite sepals; stamens 3; filaments connate into a short cylinder.

雄花：花梗丝状，3-5毫米；花萼红色的或紫色；萼片6，2列，近等长，倒卵形，2-3*约1.5毫米；花盘裂片6，与萼片对生；雄蕊3；进一个短汽缸合生的花丝。

Sepals appearing 3- or 4-merous in bud, in fact to 5-merous at anthesis, nearly free, valvate, ovate, with base appearing ± cordate when sepal erect, texture rather thick, margins slightly conduplicate.

萼片出现3-或4基数在芽中， 5基数在花期实际上，近离生，镊合状，卵形，当萼片直立时基部多少心形，质地相当厚，边缘稍对折。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
