Stamens erect, inserted at base of perianth segments; filaments free or basally ± connate; anthers basifixed, apex often adaxially appendaged; connective extended into a perianthlike, linear-lanceolate, long appendage.

雄蕊直立，着生的在花被片基部；花丝离生或基部多少合生；花药基着，先端通常附属物；药隔延长至花被状，线状披针形，长附属物。

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

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。

Female flowers: perianth lobes 4 or 5, distinct, longer than or as long as ovary, usually unequal, apex usually corniculate; staminodes as many as and opposite to perianth, scale-like.

雌花： 花被裂片4或5，清楚，长于或者等长于子房，通常不相等，先端通常具小角状突起；退化雄蕊同数的和对生于花被，鳞片状。

Male flowers: perianth lobes 4 or 5, elliptic, connate 1/2 of length, slightly valvate, apex usually corniculate; stamens as many as and opposite to perianth lobes; filaments inflexed in bud; rudimentary pistil small.

雄花： 花被裂片4或5，椭圆，合生的长度达1/2，稍镊合状，先端通常具小角状突起；雄蕊同数的和对生于花被裂片；花丝在芽中内折；不发育雌蕊小。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

本文对鹅掌楸、北美鹅掌楸和杂交F_1的花果共11 个数量性状进行分析，并应用高效液相色谱对上述三大类群花被片类黄酮糖苷配基和结合糖及类胡萝卜素进行了定性和定量研究，结果如下：鹅掌楸和杂交鹅掌楸花被片类黄酮糖苷配基为花青素、6-羟基黄酮和反式查尔酮，糖苷配基结合糖为葡萄糖、鼠李糖和半乳糖；类胡萝卜素为β-胡萝卜素和番茄红素。

Stamens 6; filaments nearly wholly adnate to perianth tube; anthers positioned distally in perianth tube, dorsifixed.

雄蕊6；花丝差不多完全的贴生于花被筒；花药在花被筒里上部确定的位置，背着。

Stamens 4 or 6, inserted at base of perianth segments or adnate to perianth tube; filaments filiform; anthers dorsifixed. Ovary 2- or 3-loculed; ovules 1 or 2 per locule.

雄蕊4或6，着生的在花被片基部或贴生于花被筒；花丝丝状花药背着子房室2或3；胚珠每室1或2。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
