小苞片

Flowers bisexual, actinomorphic but androecium often slightly zygomorphic, usually (3 or)4- or 5(or 6)-merous, perianth biseriate, perigynous; bracteoles opposite, usually caducous.

花两性，辐射对称但是雄蕊群通常稍左右对称，通常4-或5 (或6)瓣，花被双列，周位；小苞片对生，通常早落。

Leaves 3 split or 3 deep crack length 8 to 12 cm, width 7 to 10 cm, serrated edges, flowers single, born in axilla, small bracts linear, at base of calyx Hopson.

叶3分或3深裂纹长度8日至12厘米，宽7至10厘米，边缘锯齿状，花单，在腋下出生，小苞片线性，在基地的花萼霍普森。

Flowers bisexual, small; bracteoles minute, often deciduous.

花两性，小；小苞片分钟，经常脱落。

Bracteoles herbaceous, often falling in fruit; umbellules not densely crowded.

小苞片草本，经常在果期下降；小伞形花序不浓密拥挤。 23 Pleurospermum 棱子芹属

Bracteoles stiff, papery, persistent in fruit; umbellules densely crowded.

十分的小苞片，似纸，在果期宿存；小伞形花序浓密拥挤。

Leaves 3-pinnate; bracteoles 2–3-pinnate, nearly equal to umbellules.

叶3回羽状；小苞片2-3回羽状，差不多等于小伞形花序。

Leaves 3-pinnate; rays of terminal and lateral umbellules subequal; bracteoles 2-pinnate.

叶3回羽状；顶生和侧生小伞形花序的伞辐近等长；小苞片2回羽状。

Rays unequal; bracteoles subequal or shorter than umbellules.

伞辐不等长小苞片近等长或者短于小伞形花序。

Leaves 2-pinnate; bracteoles 3-lobed or 1-pinnate, subequal or exceeding flowering umbellules.

叶2回羽状；小苞片3浅裂或者1回羽状，近等长或者超过的开花小伞形花序。

Inflorescences axillary or terminal, racemes, panicles, or cymes, sometimes 1-flowered or several-flowered in a fascicle; bracteoles small, early deciduous.

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。
