对生叶

The results offer the condition that these plants of Ajuga could be distinguished by size and ornamentation of exhymenine.

结果表明，同属三种植物的形态特征相似，可通过叶形及花期是否具基生叶，花萼的形态，花冠颜色以及茎的生长方式和植株被毛情况等予以鉴别；通过对三种植物的花、根、茎、叶及全草粉末的组织构造观察，认为种间差异较小，可依据毛茸的分布及形态特征和茎的木化程度不同加以鉴别；对三者花粉粒进行了扫描电镜观察，发现其大小和外壁纹饰具有明显差异，为三者的鉴别提供了有力的依据，也为该属的分类及植物花粉形态研究提供了花粉形态学方面的资料。

Leaves basal and/or cauline, alternate, opposite, or whorled, parallel or rarely reticulate veined.

叶基生和茎生，互生，对生，或者轮生，平行脉或者很少网状脉。

Leaves cauline, lateral and pseudoterminal, alternate, opposite, or whorled, sessile or shortly petiolate, sometimes cirrose at apex.

茎生，侧的叶和假顶生，互生，对生，或轮生的，无梗或具短叶柄，有时有卷须在先端。

Leaves simple, entire or rarely gland-fringed, opposite or sometimes whorled, nearly always estipulate.

叶为单叶，全缘或少数具流苏桩腺体，对生有时轮生，几乎总是无托叶。

Leaves opposite, rarely verticillate, exstipulate; leaf blade simple, margin entire, serrate, or rarely pinnately lobed.

叶对生，很少轮生，无托叶；单叶，边缘全缘，有锯齿，或很少羽状浅裂。

Leaves alternate, rarely opposite, petiolate or subsessile; leaf blade flattened, slightly succulent, linear, lanceolate, oblong, ovate, triangular, rhombic, or hastate, margin serrate, rarely entire.

叶互生，很少对生，叶具柄或近无柄；扁平的叶片，稍肉质，线形，披针形，长圆形，卵形，三角形，菱形，或戟形，边缘有锯齿，很少全缘。

Lauraceae A family of trees and shrubs usually with simple, leathery, evergreen alternate or opposite leaves without stipules.

樟科：一科乔木或灌木植物，叶为单叶、皮革质，常绿，互生或对生，无托叶。

After filling stage, cholorophyll content in oppositifolious maize was higher than in alternative.

结果表明，对生玉米单株叶数和叶面积比互生玉米分别高出192％～220％和130％～190％。

Roots fleshy. Leaves almost all basal; stem leaves alternate; petiole long; pinnatifid to pinnatisect.

根肉质。叶几乎所有基部；茎生叶互生；叶柄长；对羽状全裂羽状半裂。

Leaves few to many, basal or along stem and opposite, seldom in whorls of 3 or alternate, unequal to equal in a pair; leaf blade puberulent to villous or velutinous, rarely glabrous, base cuneate to cordate, rarely attenuate.

叶少数到多数，基部的或沿茎和对生，成对不能胜任等长的很少3轮生或互生；对具长柔毛或茸毛，很少无毛，基部楔形到心形被微柔毛，很少渐狭的叶片。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
