叶状苞

Female flowers borne in axil of a leaflike bract in a cup formed by 2 connate bracts.

2合生的苞片形成的一个叶状的苞片在一杯的雌花生于腋。

Cyme of several clustered in the axil, usually without the total peduncle; phyllaries base Hopson, in which two wide and triangular, the length and width nearly equal, care leaf-shaped, and the other two lanceolate, long for the width of two times lobed.

聚伞花序数个簇生于叶腋，通常无总花梗；苞片基部合生，其中2枚宽三角形，长和宽近相等，托叶状，另2枚披针状，长为宽的2倍，叶状。

A reduced leaf or leaf-like structure at the base of a flower or inflorescence.

苞片 Bract 在花或花序基部的退化的叶或叶状结构。

Begonia pulvinifera is similar to B. wangii T. T. Yü, differing in the lower surface of the leaf being pale green; petiole with a reddish brown swollen base; tepals obtuse; tepals of staminate flowers 4; tepals of carpellate flowers 3 and ovary with axile placentation throughout. Begonia pulvinifera also resembles B. cavaleriei Lév., but is distinguishable by the narrower leaf; pulvinate petiole; stipules triangular with apex acuminate or cuspidate; and ovate bracts with apex acute or acuminate.

相似种类有少瓣秋海棠与昌感秋海棠：但本新种叶背面浅绿色，叶柄基部红棕色、膨大，雄花花被片四枚，雌花花被片三枚，花被片先端圆钝，且子房通体具中轴胎座，有别於少瓣秋海棠；此外，新种之托叶三角形，先端渐尖或骤尖，叶身较窄，叶柄基部具叶枕，卵状苞片先端尖或渐尖，明显不同於昌感秋海棠。

Leaf blade 10--15 cm wide, base cordate; primary lobes separate for at least 60% of blade radius; central lobe rhombic, 3-lobulate, distally few dentate, apex acute; ultimate lobules narrowly ovate; proximal leaves withered. Raceme 6--30 cm, 3--15-flowered, sometimes corymbiform, glabrous; proximal bracts sometimes leaflike, distal ones small, linear or subulate.

叶片10-15厘米宽，基部心形；初级裂片短于叶片半径的60%；中央裂片菱形，3具小裂片，上部很少具牙齿，先端锐尖；末级小裂片狭卵形；下部叶枯萎。6-30厘米的总状花序，3-15开花，有时伞房花序状，无毛；有时叶状的下部苞片，上部的小，线形的或钻形。

RT-PCR analysis showed that GhMADS1 gene expressed in petals, stamens, ovules and fibers, but not in roots, stems, leaves, bracts and sepals. The strongest expression of GhMADS1 gene was detected in petals. But in floral buds of a cotton homeotic mutant (CHV1), whose floral organs are all converted to bract leaf-like organs, the transcript of GhMADS1 gene was not detected.

RT-PCR分析显示，该基因在陆地棉的花瓣、雄蕊、胚珠和纤维中表达，特别是在花瓣中表达量最高，而在根、茎、叶等营养器官和棉花同源异型突变体CHV1（所有花器官均变为苞叶状叶性器官）的变异花蕾中不表达。

Inflorescences terminal, shorter than cauline leaves; involucral bract leaflike; heads many, hemispheric, many flowered.

花序顶生，短于茎生叶；总苞片叶状头状花序很多，半球形，多花的。

Inflorescence borne in axil of leaf or scalelike bract, of 1(--3) umbels or a panicle, raceme, or spike of umbels; peduncle sometimes with a scalelike prophyll at base.

花序生于叶或的腋鳞片状苞片，1(-3)伞形花序或一圆锥花序，总状花序，或伞形花序的穗状花序；有时的花序梗具一鳞片状的先出叶在基部。

Sepals (4 or)5, free, imbricate, or connate into a tube, leaflike or scarious, persistent, sometimes bracteate below calyx.

萼片(4-)5，离生，覆瓦状排列，或者合生成管状、叶状或者干膜质，宿存，有时在花萼下面的具苞片。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
