花瓣

Though there might be other factors involved, results suggest the formation of petaloid sepals in Mussaenda still required A, E, and some B class genes, but further survey for addition factors and functional assay for identified genes are needed.

以上结果显示玉叶金花类花瓣花萼的发育过程可能有A群、E群及部分的B群基因参与调控，虽不排除有其他因子参与的可能性，但其调控机制是否能以现有的模式解释尚待更进一步的研究。

Male flowers: sepals mostly 5, imbricate to valvate, free; petals 5, smaller or nearly equal to sepals; disk glandular, usually 5, and opposite sepals; stamens 10-20; filaments free, inflexed in bud; anthers muticous; pistillode absent.

雄花： 多数的萼片5，覆瓦状到镊合状，离生；花瓣5，小或近等长于萼片；花盘具腺，通常5，与萼片对生；雄蕊10-20；花丝离生，在芽中内折；花药钝；无退化雌蕊。

Petals 6, nectariferous, much smaller than sepals or absent.

花瓣6，分泌蜜汁，比萼片小得多或者无。

Leaves all basal, simple, 3-sect, or ternate; petals ca. 1/3 as long as sepals, not petaloid (instead specialized nectariferous organs); style ca. 2 × as long as ovary; follicles cubic-globose

叶全部基生，单，3裂，或三出；花瓣约1/3倍于萼片，不瓣状(代替为特化的分泌蜜汁器官)；花柱长约2 *倍于子房；蓇葖果立方球状 18 Urophysa 尾囊草属

The results showed that flower shaped, nubbly shaped and column shaped W2C particles formed by in-situ reaction, were dispersed in Ni-based coating. The microhardness of the coating is 838 HV, 8 times of copper substrate.

结果表明：激光原位反应使镍基涂层组织内原位生成了弥散分布的花瓣状、块状以及柱状的W2C颗粒，涂层的显微硬度达到了838 HV，是铜基体的8倍。

In Nymphaea, 4 sepal primordia initiated from abaxial to adaxial side of the floral apex. Petal and stamen numerous, initiated in spirals. The apex of floral primordium caved in at the late stage.

睡莲的萼片4枚，向轴式发生；花瓣和雄蕊多数，螺旋状向心式发生；花原基的顶端在后期向下凹陷；心皮6～8枚，呈一轮同时发生，为对折型心皮。

Xie falling petals open water, attracting between planktonic algae in the group of Nymphoides fish, falling for the play chase.

开谢的花瓣飘落水中，吸引着浮游于荇藻间的群鱼，作追逐落花的嬉戏。

Petals obcordate, white to dark purple, 1–1.5 mm.

花瓣倒心形，白色到深紫色，1-1.5毫米。

Petals pink to rose-purple or white , obcordate or obtrullate, notched at apex.

花瓣粉红色到玫瑰色紫色或白色，倒心形或者倒镘形，开槽在先端。

Calyx teeth obsolete. Petals obcordate, white, often purplish on reverse, ca.

萼齿不明显倒心形的花瓣，白色，通常在反面上略带紫色的，约2×1.2毫米。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
