叶脱落 叶柄3-4厘米，近无毛；叶片卵形的或卵状长圆形， 9-13 *长约8厘米，纸质，密被红棕色短柔毛在脉上，正面无毛，基部近心形，边缘重细锯齿具紧贴锐尖齿，3裂；三角状心形的中间裂片，先端渐尖；叶片的侧的裂片在上半部分，很多短和先端锐尖。

Verticillasters in dense capitula or spikes, or widely spaced; bract margin acute serrate or spinescent, rarely entire.

在紧密的头状的或穗状花序，或稀疏排列里的轮状聚伞花序；苞片边缘锐尖的有锯齿或者具刺，很少全缘。

Calyx teeth obsolete or minute; vittae 1 to several in each furrow.

叶2-3回羽状，末回裂片卵状披针形到线形，浅裂的有锯齿或的通常；翅加厚，但不是木栓质使在基部扩大。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

在诱导条件下，这些突变体表现出不同的形态和结构的变化，共有22个表型和结构发生变化。20个突变系发芽率或存活率较低，发芽率由10％—60％，其中2个突变系存活率分别为0％和50％。5个突变系在茎或下胚轴的结构上发生变化，其中一个突变系arris-stem发生如下表型变化：从真叶出现至开花结实的整个生长期，生长速度要明显比野生型拟南芥缓慢；叶缘有明显锯齿，莲座叶呈螺旋状排列；茎的基部有较多侧枝，侧枝间距明显缩短，茎有明显扭曲；突变体茎侧面有1至数条棱形突起，内部存在一至数个排列紧密的细胞团，由多层细胞呈环形排列，细胞壁明显加厚，内部存在管状分子，推测为维管组织。

Mm, glabrous or adaxially sparsely setose, apically shortly acuminate, margin serrate; bases of petiole and petiolules without stipulelike appendages or with only hairlike appendages; pedicels rough; rootstock usually 1- or 2-fascicled

小叶约1毫米，无毛或稀疏刚毛，顶部短渐尖，边缘有锯齿；叶柄基部和小叶柄没有托叶状附属物或具毛状附属物的只；花梗粗糙；根茎通常1或2簇生 6

"Sargassums are also known as sea holly because of their highly branched stems with hollow, berrylike floats and many leaflike, sawtooth-edged blade s."

马尾藻还因其高度分支、浆果状气囊和许多带锯齿边缘的叶片状拟叶而被称为海冬青。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
