Flowers usually in cymes, panicles, or racemes, rarely solitary, usually bisexual, rarely unisexual, hypogynous or ± epigynous, rarely perigynous, usually biperianthial, rarely monochlamydeous, actinomorphic, rarely zygomorphic, 4- or 5(-10)-merous.

在聚伞花序里的通常的花，圆锥花序或总状花序，很少单生通常两性，很少单性，有时的萼片象花瓣一样。

Stamens (6-)12-100+, inserted at or near base of floral tube, exserted, dimorphic in most species, 6 solitary in front of sepals with thick filaments and large anthers, 12-100+ in clusters in front of petals with thin filaments and small anthers, rarely monomorphic, then all filaments thin, subequal.

雄蕊(6-)12-100 +，着生在花被管或其近基部，外露，在大多数种里二形，在萼片前前面的6单生具粗的花丝和大的花药，在花瓣前12-100＋簇生具细的花丝和小的花药，很少同型，同型则花丝细，近等长。

Leaves narrowly oblanceolate, 1-2.5 cm; sepals triangular to narrowly elliptic; petals 4-4.5 mm, apex shortly mucronate

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。
