Calyx of 5 subequal teeth, lanceolate to narrowly triangular; leaves clearly pinnatisect.

Stem leaves petiolate, petioles ca. 10 cm; sheaths broadly ovate, 2.5–4 cm, purple-red adaxially, densely white-setose abaxially; blades triangular-oblong, 10–15 × 5–7 cm, 3-pinnate; pinnae 5–7 pairs, only basal pinnae short-petiolulate; ultimate segments obovate or oblanceolate, 3–5 × 2–3 mm, setose along nerves abaxially, entire or 2–3 toothed, cuspidate at apex.

茎生叶具叶柄，叶柄约厘米；鞘宽卵形，正面2.5 -4厘米，紫红色，密被白色具刚毛；叶片三角形的长圆形， 10-15 * 5-7 厘米，3回羽状；羽片5-7 对，只是基本的羽片短的小叶柄；末回裂片倒卵形或倒披针形， 3-5 * 2-3 毫米，具刚毛沿着叶脉背面，全缘或齿状，骤尖在先端。

The technical characteristics of the invention is that: the rotor end face tooth profile contains four, five or six sections of tooth curves with the circular nature; when it has five sections, addendum circular arcs and dedendum circles are added to the addendum or the dedendum of the rotor; when it has six sections, both the addendum circular arcs and the dedendum circles are added to the addendum and the dedendum of the rotor at the same time, to form four different combination schemes; there are common tangents at the connection points of the two adjacent teeth forming curves, which has a smooth tooth-profile without cusp, a high-wearing feature, a long life of the rotor, a small leakage triangle, and a good sealing property.

本发明的技术特征是：转子端面齿型是包含四段、五段或六段圆弧性质的齿曲线；当为五段时，在转子的齿顶或齿根加上齿顶圆弧或齿根圆弧，当为六段时，在转子的齿顶和齿根同时加上齿顶圆弧和齿根圆弧，形成四种不同的齿型组合方案；相邻的两组成齿曲线的连接点处具有公切线，齿型光滑，没有尖点，耐磨性好，转子的使用寿命长，泄漏三角形小，密封性好。

Middle tooth of upper lip of calyx wider than lateral teeth, circular-ovate; lateral teeth broadly lanceolate to narrowly triangular.

中间齿的上唇的花萼宽比侧齿，圆卵形；侧的齿宽披针形的到狭三角形。

Calyx teeth triangular to ovate-triangular.

萼齿三角形到卵形三角形。

Calyx tube conspicuously 4-dentate; teeth ovate-triangular.

显著的萼筒4有齿；齿卵状三角形。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
