离生叶的

托叶2，离生，早落，留下一短的横裂痕在叶基每边。

Flowers free from rachis; leaves usually well developed.

花离生的轴；叶通常发育良好。

Leaves alternate; stipules small, undivided, caducous; petiole with 2 apical glands; leaf blade entire, pinnately veined, eglandular above, below with a pair of distinct basal glands and with additional smaller submarginal glands.

叶互生 ；托叶小，没有分开，早落；叶柄具2顶端的腺体；全缘的叶片，成羽状脉，在上面无腺体，在下面具一对离生的基部腺体并且具另外的小的近缘腺体。

Foliage leaf sheath with interior ligule and a less distinct external ligule, often with well-developed auricles and/or oral setae; blade deflexed, broad, roughly linear-lanceolate, base narrowed into pseudopetiole, articulating and eventually separating from persistent sheath, transverse veinlets often forming distinctly tessellate venation.

叶叶鞘具内部叶舌和一个不怎么离生的外部叶舌，通常具发育良好叶耳和/或口头的刚毛；外折的叶片，宽，粗糙线状披针形，对假梗的基部狭窄，有节并且最终从宿存鞘，横裂细脉通常分开清楚形成脉序。

Basal leaves numerous, fasciculate, rosulate; stipules free, brown, linear-lanceolate, margin fimbriate-serrate; petiole 1.5-4 cm, very narrowly winged in upper part; blade ovate or triangular-ovate, 1.3-3.5 × 1-3 cm, both surfaces glabrous to subglabrous or appressed puberulous, with dense brown glandular dots, veins conspicuously raised abaxially, base shallowly cordate or cuneate, margin serrulate, apex ± acute.

基生叶多数，束状，莲座状；托叶离生，棕色，线状披针形，边缘流苏状使成锯齿波；叶柄1.5-4厘米，具狭翅在上半部分；叶片卵形的或三角状心形， 1.3-3.5 * 1-3 厘米，两面无毛到近无毛的或者贴伏被微柔毛，具密的棕色腺点，脉明显在背面突起，基部浅心形或楔形，边缘细锯齿，先端多少锐尖。

Styles free, usually less than 1.4 × as long as ovary; leaves usually laxly or not visibly reticulate-veined abaxially

花柱离生，通常少于1.4 *倍于子房；叶通常稀松的或不明显网状脉背面 14

At least basal leaves dentate, serrate, or pinnatifid; median filaments free; stems glabrous or with straight trichomes.

至少基生叶具牙齿，使成锯齿波，或羽状半裂；中间的花丝离生；茎无毛的或具直的毛状体。

Scalelike leaves present; leaves developing after anthesis, petiole narrow, leaf blade distinct.

存在的鳞片状叶；叶发育的在花后，叶柄缩小，叶片离生。

Using the technique of culturing shoot apex under aseptic conditions, we found that there is a sensitive stage for the sex expression of earlier flower buds, this stage is located before the second leaf full expansing.

利用黄瓜茎尖离体培养系统结合生物切片技术观察了黄瓜早期发育阶段中成花分生组织的发生及发育情况，结果表明：就黄瓜早期发育的花芽而言，可能存在着一个性别决定的敏感点，而这个敏感点位于第二片真叶展开前的某个阶段，此时的花芽绝大多数尚处在花分生组织阶段。

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。
