查询词典 bracteole

Flowers bisexual, arising from axils of small bracts, erect, small, often subtended by a bracteole.

花两性，生于小苞片腋的，直立，小，通常被小苞片包着。

Flowers solitary; bract and bracteole borne on or at base of pedicel; perianth lobes connate at base; stamens 6, all fertile.

花单生 苞片和小苞片生于花梗上或在花梗基部；花被裂片在基部合生；雄蕊6，全部能育。

Raceme elongate and lax to short and dense but not capitate; bract and bracteole usually borne at or near apex of pedicel.

总状花序拉长，对短疏松和紧密但不是头状；苞片和小苞片通常着生在花梗的先端或近先端。

Raceme rachis and pedicels pubescent or puberulent; bract and bracteole usually borne on distal 1/2 of pedicel.

总状花序轴和花梗具短柔毛或微柔毛；苞片和小苞片通常生于花梗上部的1/2。

Raceme rachis and pedicels glabrous; bract and bracteole borne on proximal 1/2 of pedicel.

总状花序轴和花梗无毛；苞片和小苞片生于花梗下部1/2。

Bracteole apex 1-pinnate/pinnatifid; ultimate leaf segments lanceolate, 0.5–5 mm broad; pedicels terete.

Bracteole 顶1回羽状/羽状半裂；披针形的末级叶裂片，宽的0.5-5毫米；花梗圆柱状。

Pedicel bearing a bract and bracteole toward either base or apex, pubescent, puberulent, or glabrous; bracteole similar to bract but smaller.

花梗向基部或先端生苞片和小苞片，短柔毛，被微柔毛，或无毛；小苞片类似苞片但是更小。

The basic structure of the inflorescence is the cyme (branchlets arising from the bracteole axils, the bracteoles serving as bracts for upper flowers), which can be reduced to one flower with two bracteoles and a bract. Units of dispersal vary considerably (capsules opening with lower part persistent, flower and bracteoles falling together, or cymose partial inflorescences breaking off above bract) and can be characteristic for genera. Several genera possess long trichomes serving dispersal at the base of the tepals.

花序的基本的结构是聚伞花序小枝起因于bracteole腋，散布的单位变化多样(蒴果开裂下半部分的宿存，花和小苞叶一起脱落，或部分聚伞花序在苞片以上裂开并且可以作为属的特征一些属在花被片的基部有长的毛状体用于散布Digera arvensis Forssk吗？

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

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。
