Female flowers at base of inflorescences, larger than male ones, each bract-axil with only 1 female flower; pedicel short but distinct; calyx, rarely 2-sepaled, slightly fused at base; petals and disk absent; ovary 2-celled; ovules 1 per cell, smooth; styles short; stigmas 2, revolute, entire, eglandular.

雌花在花序的基部，比雄花大，每苞片腋只具1雌花；花梗短但是明显；花萼，很少2萼片，稍在基部愈合；花瓣和花盘无；子房2室；胚珠1 每室，平滑；花柱短柱头2，外卷，全缘，无腺体。

Fruiting pedicels ascending to divaricate, glandular or eglandular, lowermost 1-2.5 cm. Sepals purple, linear to linear-oblong, 9-12 × 2-3 mm, glabrous, pubescent, or glandular, white margined.

到极叉开，具腺或上升的果梗，最下萼片紫色1-2.5 厘米，线形到线形长圆形， 9-12 * 2-3 毫米，无毛，短柔毛，或具腺，白色的边缘。

Leaves oblong or oblong-ovate; scale-leaf at base of scape narrowly ensiform; sepals oblong, 2.5–3 mm; style not exserted.

叶长圆形或长圆状卵形；鳞叶在花葶基部狭剑形；萼片长圆形，2.5-3毫米；花柱不外露。

Ovary with as many locules as sepals, rarely more, apex flat or conic, often with a depressed nectary surrounding base of each epipetalous stamen; stigma capitate or hemispheric, entire or lobed, upper 1/2-2/3 receptive.

子房室与萼片同数，很少更多，先端平或圆锥形，通常具一背腹扁平蜜腺围绕每个花瓣上着生的雄蕊的基部；柱头头状或半球形，全缘的或浅裂，上面的1/2-2/3有感受性。

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。
