萼片

Sepals imbricate, enlarged in fruit; petals circinate in bud, much longer than sepals.

萼片覆瓦状，在果期扩大；拳卷的花瓣在芽中，远长于萼片。

Sepals (2-)4 or 5(or 6), imbricate or decussate or rarely wholly united in bud, inner ones sometimes petaloid.

萼片(2-)4-5(-6)，在芽期覆瓦状排列或交互对生或很少完全合生，内部的萼片有时花瓣状。

Leaves narrowly lanceolate to linear-lanceolate, base cuneate; plants glabrous; epicalyx segments shorter than to equaling sepals.

叶狭披针形的到线状披针形，基部楔形；植株无毛；为了等于萼片的副萼片短于。 2 L。 virgatum 帚枝千屈菜

Leaves ovate-lanceolate to broadly lanceolate, base rounded, truncate, or semiclasping; plants typically sparsely to densely pubescent; epicalyx segments much longer than sepals.

离开卵状披针形到宽披针形，基部圆形，削去，或；通常的植株疏生到密被短柔毛；副萼片远长于萼片。 1 L。 salicaria 千屈菜

Leaves simple, mostly palmately lobed or parted; sepals valvate, epicalyx segments present; stamens 1–5; style basal or sub-basal; flowers usually in corymbose cymes, always bisexual.

单叶，多数掌状浅裂或深裂；镊合状的萼片，副萼片宿存；雄蕊1-5；花柱基部的或近基部；在伞房状聚伞花序，总是是阴阳人里的通常的花。

Corolla tube shorter than sepals; calyx with basal glands only inside sepal edges; leaves without a strong intramarginal vein.

花冠筒短于萼片；只在萼片边缘里面的花萼具基部腺体；叶没有一强壮的边脉。

Corolla lobes as many to 2 X as many as sepals, usually entire, rarely with 2 lacerate or lobular appendages.

花冠裂与萼片同数或为萼片数的两倍，通常全缘，很少有2个撕裂状或者片状的附属物。

Sepals caducous after flowering, rarely one outer sepal persistent; keel with apical appendage flabelliform and lobed or laciniate flowers unknown in P. oligosperma

萼片早落花后，宿存的一外部萼片的很少；条裂的龙骨状具顶端附属物fmabelliform 和浅裂或(在oligosperma页花未知) 20

Sepals 6.6-7.8 mm, mucro 1.6-2.5 mm, ratio of mucro/sepal length = 0.22-0.37, outside with 0.1-1.2 mm antrorse to patent nonglandular trichomes, inside glabrous.

萼片6.6-7.8毫米，短尖头1.6-2.5毫米，短尖头/萼片长度比率=0.22-0.37，外面具0.1-1.2毫米向前到开展的非腺毛，里面无毛。

Scape erect or slightly slanting, 30cm high, 1-2flowered, flowers large, white ,8-10cm across, fragrant; sepals oblong-lanceolate, 6cm long, 2cm wide, faintly tinted green at base; petals slightly smaller than sepals, lip 3-lobed, side lobes erect, spotted purple-red, mid –lobe pendent, blotched yellow and irregularly spotted purple-red in middle ,wavy at margin, lamellae yellow ,short-hairy .

花葶直立或微倾斜，高30cm ，有1~2花，花大，白色，直径8~10cm ，具芳香味；萼片长圆状披针形，长6cm ，宽2cm ，基部微带绿晕；花瓣稍小于萼片，唇瓣3裂，侧裂片直立，有紫色小斑点，中裂片下垂，中间有黄色斑块和不规则紫红色小斑点，边缘波浪状，褶片黄色，被短毛。花期2~5月。

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。
