Historically, plants of this affinity with stamen number equal to sepal number were Ludwigia , and those with stamens twice as many as sepals were Jussiaea , but Raven and others demonstrated reticulate variation in this character, and treated the two groups as a single genus.

历史上，常具有与萼片数相同的雄蕊数的植株为 Ludwigia的，而雄蕊数为萼片的2倍的是Jussiaea的，但 Raven和其它人证明这一特征成网状式的变异，并且把这两个类群归入同一属内。

Sepals purple-blue or blue, abaxially puberulent; spur subulate or cylindric-subulate, 1.5--2 (--2.2) cm, straight or slightly recurved, base 2.5--3.5 mm in diam.; other sepals 1--1.9 cm.

萼片紫色蓝色的或蓝色，背面被微柔毛；距钻形或圆筒状钻形的，1.5-2(-2.2)厘米，直或稍下弯，基部2.5-3.5毫米直径；其它的萼片1-1.9厘米。

Outer 3 sepals linear-oblong, 1--1.5 × 0.3--0.4 cm, apex obtuse; inner 3 sepals smaller.

外部3个萼片线形长方形， 1-1.5 * 0.3-0.4 厘米，先端钝；小内部3萼片。

Leaf blade abaxially densely grayish white appressed stellate-tomentose throughout; sepals ovate-deltoid, 1.5–2.5 × 0.8–1.2 mm, midvein usually abaxially distinct or sepals keeled at anthesis; stamens included.

全部的浓密的叶片背面浅灰色的白色的贴伏的被星状绒毛；萼片卵形正三角形， 1.5-2.5 * 0.8-1.2 毫米，中脉通常离生或萼片龙骨状在花期；雄蕊内藏 3 Clethra petelotii 白背桤叶树

花朵呈直立状或平展，花径达3-10cm.4个萼片但是有时会有5-6个萼片，白色，粉色，深紫红色。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
