Female flowers 1-3 per bract, often sessile; bracts often dentate or lobed, accrescent in fruit; sepals 3-5, shortly connate, imbricate; ovary (2 or)3-locular; styles mostly free, laciniate.

雌花1-3 每苞片，通常是无梗；苞片经常具牙齿的或浅裂，在果期增大；萼片3-5，短，覆瓦状；子房2(或3)室；花柱多数离生，条裂。

A segment of a perianth which is not differentiated into calyx and corolla; a sepal or petal.

花被片 Tepal 无花萼和花冠之分的花被片；萼片或花瓣。

Female flowers with an entire bract adnate to ovary, free at apex; bracteoles 2, adnate to ovary, free at apex; sepals 4, adnate to ovary, free at apex; style elongate with recurved branches; stigmas carinal, 2-lobed, plumose.

Flowers bisexual or unisexual, regular, hypogynous, solitary or in cymes or thyrses; bracteoles often inserted just beneath calyx and then not always easily distinguishable from sepals.

花两性或单性，整齐，下位，单生或组成聚伞花序或聚伞圆锥花序；小苞片通常着生在花萼正下方，小苞片于萼片不容易区分。

Scapes 2 or 3, few flowered; involucral bract petiole 1--3 cm; bracteoles present, small; sepals puberulent.

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

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。
