萼

Has a brilliant red color and is a good source of anthocyanins. Roselle calyx possesses unique flavor, high acidity and low sugar. Extraction methods can be used to produce drinks.

为鲜艳红色，是良好花青素来源，果萼并具独特风味、酸度高和糖度低等特性，故利用萃取方式，制成饮品。

Its results showed that ratio of length to width of petal and sepal and the degree of flat of achene within population were characterized as the most stable characters and gradually increased with the increase of latitude.

结果表明，居群内，瘦果扁平度、花瓣长宽比、萼片长宽比变异最为稳定，居群间，这3个繁殖器官的相对性状呈现随着纬度的增加逐渐增大的趋势，并且随纬度的增加，核型不对称系数呈现不断增加而染色体总长不断减小的趋势。

Sepals (3 or)4 or 5(-7), green, persistent after anthesis.

萼片(3或)4或5(-7)，绿色，花后宿存。

Calyx completely united in bud, splitting at anthesis into 2[or 3] sepals after.

花萼在芽中完全合生，使在花期分裂，以后成2 [或3 ]萼片的。

We explore these questions in Legume model system, Lotus japonicus. Compared with model plants Antirrhinum and Arabidopsis, floral pattern formation of Lotus japonicus is different in several aspects. Floral organs initiate in an order of sepals, carpel, petals, stamens. Within each whorl, organs initiate unidirectionally from ventral side to dorsal side. Initiation of organs in different whorl overlaps. Stamens exist in both 2nd whorl and 3rd whorl, and 2nd whorl is heterogeneous for the existence of different identity organs .

与模式植物金鱼草和拟南芥相比，豆科模式植物百脉根的花模式建成有其特殊性：一、花器官从腹部向背部单向起始；二、器官起始顺序是萼片—心皮—花瓣—雄蕊；三、不同轮的器官起始时间相互重叠；四、相同属性的器官出现在不同轮中；五、第二轮不均一，出现不同属性的花器官；六、花瓣和雄蕊不单独起始，而是经过了短暂的花瓣—雄蕊共同原基的阶段。

Leaves prominently black punctate-lineate; bracts subulate, bracteoles and calyx lobes longer than wide, apery, apex acute

显著的叶黑色具点具线纹；苞片钻形，小苞片和萼裂片长于宽，学样，先端锐尖 21 Maesa hupehensis 湖北杜茎山

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

Flowers upright , more or less spreading ,3-10cm across. Tepals 4 but sometimes 5-6,white ,or pink to dark red-purple.

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。

Flowers nodding , campanulate or spreading ,3-8cm across .Tepals 4 but sometimes 5 or 6,white,cream, yellow, or yellow stained with red-purple.

花朵低垂铃形或平展，花径达3-8厘米。4个萼片但有时是5或者6个萼片，白色，奶油色，黄色，或黄中带紫红色。

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。
