Male inflorescences cymose, paniculate, moniliform spicate, or capitate, without a receptacle and involucres.

雄花序聚伞状，圆锥状，念珠状穗状的，或头状，没有一个花托和总苞 4 P 。 sect。 Urticella 三萼组

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。

Capsule cylindric, ca. 3 X as long as persistent calyx, apex mucronate.

蒴果圆筒状，约X倍于宿萼，先端短尖。

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

叶狭倒披针形，1-2.5厘米；萼片三角形的到狭椭圆形；短的花瓣4-4.5毫米，先端短尖 78 S。

Sepals narrowly elliptic, 2-3 mm, densely hirsute, apex mucronate.

萼片狭椭圆形，2-3毫米，具浓密长硬毛，先端短尖。

Flowers white, small, ca. 2 cm. Lateral sepals 2, ovate-orbicular, small, mucronulate.

花白色，小，约2 厘米侧生萼片2，卵圆形，小，具小短尖。

Stems twining; sepals rounded or obtuse apically, not mucronulate.

茎缠绕 顶部的萼片圆形的或钝，不具小短尖。

Flowers purplish; lateral sepals obliquely ovate, apex long mucronulate.

花略带紫色；斜卵形的侧生萼片，先端具长的小短尖。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
