Sepals 3(or 5); lateral sepals free or connate, margins entire or serrate; lower sepal large, petaloid, usually navicular, funnelform, saccate, or cornute, tapering or abruptly constricted into a nectariferous spur broadly or narrowly filiform, straight, curved, incurved, or ± coiled, swollen at tip, or pointed, rarely 2-lobed, rarely without spur. Petals 5, free, upper petal flat or cucullate, small or large, often crested abaxially, lateral petals free or united in pairs. Stamens 5, alternating with petals, connate or nearly so into a ring surrounding ovary and stigma, falling off in one piece before stigma ripens; filaments short, flat with a scalelike appendage inside; anthers 2-celled, connivent, opening by a slit or pore.

萼片3(或5)；侧萼片离生或者合生，边缘全缘或者有锯齿；更低的萼片大，瓣状，通常舟形，漏斗状，囊状，或具角状突起，渐减突然或缢缩进一分泌蜜汁具距或宽狭丝状，花瓣5，离生，上面的花瓣平坦的或者兜状，雄蕊5，与花瓣互生，合生或者近合生成环而围绕子房和柱头，在柱头成熟之前完整地从上面落下；花丝短，扁平，在里面的有一鳞片状附属物；花药2室，靠合，通过一条裂缝或者孔开裂。

The extrafloral nectaries in Cerasus plants located on the base of the petiole or edge of the blade, and belonged to stalk nectries. The nectaries consisted of epidermis, nectariferous cells and vascular bundle.

结果表明，樱属植物花外蜜腺位于叶柄基部或叶片边缘处，属于茎轴蜜腺，是由条状纹饰的分泌表皮、产蜜组织和维管束构成。

This suggests that the cytological changes in sieve element and nectariferous tissue are closely associated with the nectary functional activities.

这反映了蜜腺发育过程中筛分子和蜜腺组织的细胞学变化是与蜜腺的生长、发育和生理功能的完善联系在一起的。

Basing on the nectary structure and polysaccharied changes, it was supposed that storing of per-nectar and decomposing of polysaccharide were conducted in nectariferous tissue. The epidermis was the main place where processing of per-nectar and synthesizing and secreting of nectar were conducted.

根据花外蜜腺的特点及多糖的变化分析，原蜜汁的贮存及多糖的降解主要在产蜜组织细胞中进行，而分泌表皮细胞则是原蜜汁的加工及蜜汁的合成与分泌的主要场所，且分泌细胞内含有浓厚的细胞质，有显著的细胞核和大量的细胞器。

The results are as follows:(1) The morphological investigation indicated that the nectaries werelacked on the main nervation, calyx and bract of cotton line 97014 comparedwith TM-1. Alveolate hollow was absent at main nervation of the mature leaf.Results of cytological analysis showed that 97014 lacked nectariferous structure.Where nectary inserted were parenchyma cells, cupped structure and brownnectariferous substance on the lower epidermis were not found.

主要研究结果如下：(1)以棉花无蜜腺品种97014与有蜜腺棉花遗传标准系TM-1为材料，进行形态学比较研究，结果表明棉花无蜜腺品种97014叶片中脉、花萼和苞叶上都缺少蜜腺，成熟叶片叶脉、花萼和苞叶上均无蜂窝状凹陷；组织与细胞切片观察发现，97014缺少蜜腺组织结构，在蜜腺着生处为排列整齐的薄壁细胞，且在下表皮看不到凹陷的组织结构和褐色的蜜腺分泌物。

Female flowers: tepals 4-6; ovary with 2 or 3 locules; styles 2 or 3, long; stigma decurrent to middle or middle-lower part of style; bracts and tepals ciliolate; interstylar nectaries or nectariferous tissue lacking.

雌花： 花被片4-6；子房具2或3子房室；花柱2或3，长；柱头下延至花柱中部或中下部；苞片和花被片具短缘毛；内花柱蜜腺或分泌蜜汁的组织无；果为核果

Filaments free, very short; anthers free or mostly connivent into a sheath around ovary, 2 anterior ones with spurlike or wartlike and nectariferous appendages at base, these extending into anterior spur, connectives produced apically into conspicuous, membranous appendages.

花丝离生，非常短；花药离生或多数在子房周围靠合成为鞘，前面2枚基部具距状或瘤状和分泌蜜汁的附属物，这些延伸进入前面的距中，药隔顶部生明显、膜质附属物。

Tepals 6, free, usually connivent, sometimes strongly recurved or revolute, white, yellow, greenish, or reddish to purplish, nectariferous near base adaxially; nectaries usually narrowly grooved, sometimes fringed with papillae or hairs, rarely flat on outer tepals.

花被片6，离生，通常靠合，有时强烈下弯或者外卷，白色，黄，带绿色，或者带红色到略带紫色，蜜腺通常的具狭窄凹槽，有时具流苏具乳突或毛，很少在外部花被上平。
