Leaves with petiole 15-50 cm; leaflets 2-8 pairs; petiolules short, less than 5 mm, stout; blades abaxially becoming brown when dry, adaxially deep green, slightly shiny, first pair ovate, evidently smaller, gradually larger toward leaf apex, elliptic-ovate to narrowly elliptic, 3-20 cm, leathery, abaxially densely tomentose, adaxially hairy only on midvein and lateral veins, lateral veins ca. 10 pairs, tips not reaching margin, base broadly cuneate to rounded, margin entire, apex obtuse or rounded, rarely acute. Inflorescences compound racemose, only branched once, densely flowered on upper part of branches; bracts subulate.

叶柄15-50厘米；小叶2-8 对；小叶柄短，不到5毫米，坚固；干燥时的叶片背面的变得的棕色，正面深的绿色，稍发亮，第一对卵形，明显小，逐渐大在叶先端，椭圆状卵形的到狭椭圆形，3-20厘米，革质，背面的密被绒毛，正面有毛的只在中脉和侧脉上，花序复总状，只是分枝一次，在分枝的上半部分上的花密集；苞片钻形。

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。
