axil n.【植物;植物學】腋〔葉子,枝子同莖之間的角度〕。

axile

And the viviparous plantlets of both species are formed for the differentiation of floral primodium , but the position if viviparous plantlets is different . for the species of polygonum viviparum l . , the viviparous plantlets are formed in the inflorences , while in saxifraga cernua l are in the leaf axils . on the results of observation for morphology and anatomy , vascular bundles of viviparous plantlet are connected with that of their parent 從來源和性質看,二者的胎生苗均由花原基直接分化形成;但從位置上看,珠芽蓼在花序中形成胎生苗,而珍珠虎耳草則在地上莖的葉腋部位形成胎生苗;從形態解剖角度觀察,胎生苗的維管束與母體的維管束直接相連,胎生苗脫落時,其上已長出葉片1 - 3枚。

Leaves 2 , arising from the scale axils , membranous , elliptic to ovate , 1 - 4 cm long and 0 . 5 - 2 cm wide , apex rounded or slightly acute , base rounded or cuneate , margin entire and wavy ; veins 3 , middle veins conspicuous , margin veins ca . 0 . 5 mm from the edge ; petiole 1 - 4 . 5 cm long 葉2片自鱗片腋部生出,薄膜質,長橢圓形或卵形,長1 - 4厘米,寬0 . 5 - 2厘米,先端圓或略尖,基部圓形或楔形,邊緣全緣呈波狀;葉脈3條,中脈明顯,緣脈距葉緣約0 . 5毫米;葉柄長1 - 4 . 5厘米。

Flowers solitary in axils of leaves ; corolla nearly rotate , 2 - 3 cm long , white or pinkish , the upper lobes tinged with purplish blue blotches inside ; stamens 5 ; ovary ovoid , covered with short stipitate glandular hairs 花單生于葉腋;花冠近輻狀,長2 - 3厘米, 5裂,白色或帶粉紅色,上部裂片內有紫藍色斑;雄蕊5 ;子房被具短柄的腺毛,卵圓形。

Leaves leathery , ovate , obovate , elliptic or obovate - elliptic , 4 - 9 cm long and 1 - 4 cm wide , with 3 - 6 obtuse teeth on each side ; abaxially with tufts of hairs at axils of veins ; lateral nerves 7 - 10 pairs 葉革質,卵形、倒卵形至橢圓形或倒卵狀橢圓形,長4 - 9厘米,寬1 - 4厘米,每邊有3 - 6鈍齒,側脈7 - 10對,背面脈腋有小毛叢。

During flowering period , the decapitated 3yr old potted irwin mango showed three types of growth in axil - normal flower inflorescence , mixed panicle and new shoots 摘要盆栽3年生愛文檬果枝條于花期去頂后,葉腋側芽可分化成正常的花序、混合花序與新梢等三種類型。

The axillary branching process generally involves two developmental stages : the formation of axillary meristems in the leaf axils and subsequent axillary bud growth 植物的側枝發生一般分為兩個步驟:在葉腋處形成側芽原基,隨后側芽原基生長發育成側枝。

Bract scale the structure found in large numbers in the female cone of gymnosperms , each bearing an ovuliferous scale in its axil 苞鱗:在裸子植物的雌球果中大量存在的結構,每個苞鱗都包含一個珠鱗。

In the early january , ovuliferous scale primordial were acropetally formed in the axils of the developing bracts 翌年1月初,在苞片原基的葉腋處,珠鱗原基發生,發生方向亦為向頂發育。

Examples of epiphytes are ferns growing in the axils . 附生植物的例子是長在樹枝腋上的蕨。
