叶胚根，丛生； peti纤细的ole，(2-)4-9(-11)厘米；叶片圆形，圆形的椭圆形，或卵形，即使在相同的植株上也易变，( 0.5-)1.5-5 *(0.3-)1.5-5.5 厘米，薄革质，背面的苍绿色，正面深绿色，基础截形，近心形，或渐狭和短下延成叶柄，次脉在中脉两边各3或4。

Leaves simple, rarely trifoliolate, opposite, sessile or shortly petiolate, no more than 5 mm; blade ovate to oblong-ovate, 11-14(-16.5)× 5.5-7(-8) cm, coriaceous, glabrous, adaxially lustrous green, abaxially pale green, main vein impressed adaxially and prominent abaxially, lateral veins 5-9(-11) pairs, slightly discernible adaxially and conspicuous abaxially, base subcordate, rarely rounded, margin glandular crenate or -serrate, apex apiculate, cusp 5-10(-15) mm.

单叶，很少具三小叶，对生，无梗或短具叶柄，顶多5毫米；叶片卵形到长圆状卵形， 11-14(-16.5)* 5.5-7(-8)厘米，革质的，无毛，正面的是有光泽的绿色，背面的淡绿色，主脉正面凹陷和突出背面，侧脉5–9(–11)对，正面稍可见，背面明显，基部近心形，很少圆形，边缘腺状圆齿或腺锯齿，先端具细尖，尖突5–10(–15)毫米。

When cultured on the medium with different auxin , root segments could elongate and branch, and the addition of 1mg/l IBA into the medium was the most suitable for long-term root culture. Calli could be induced from root explants in the presence of 2, 4-D and when transferred onto E medium, they transformed further into embryonic calli which could develop into normal plants through the stages of globular-embryo, heart-shaped embryo, torpedo-shaped embryo, cotyledonary embryo.

培养基中添加生长激素（IAA，IBA，NAA）能够诱导无菌苗根切段的生长和分枝形成；而1mg／l IBA的存在，最适合于根的长期离体培养。2，4-D的存在能够诱导根外植体脱分化形成愈伤组织，愈伤组织转移至E型分化培养基能够转变成胚性愈伤组织，并进一步经球形胚、心形胚、鱼雷形胚、子叶形胚发育成正常植株。

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。
