匍匐黄细心(Boerhavia repens)是紫茉莉科 黄细心属的一种植物。 [1]
匍匐黄细心形态特征
一年至多年生草本。茎匍匐,从主根向周围延展,可至50cm。大多数部分无腺体、被微柔毛。
叶柄可达1cm,叶片长1-2.5cm、宽0.4-1.5cm,全缘,叶背呈明显的苍白色,叶基圆形或楔形,先端圆或稍尖。花序多腋生,伞形花序具2-5花,有时聚集为聚伞花序。花梗长1mm。花被白色、粉色或淡紫色,长1mm。雄蕊2(少为1或3)。掺花果棍棒状,长3-3.5mm,具5棱,疏生微柔毛,有时具无柄腺体。
该种常与黄细心(Boerhaviadiffusa)混淆。该种最显著的区别是叶缘少有多裂纹毛、花总具梗,以及更苍白的花被。该种果实形状复杂多变,这点也与黄细心(Boerhaviadiffusa)不同。
匍匐黄细心生长环境
晴朗干燥的地区,不定。
Herbs ephemeral to perennial. Stems prostrate, radiating from taproot, to 50 cm, most parts eglandular-puberulent. Petiole to 1 cm; leaf blade 1-2.5 × 0.4-1.5 cm, abaxially conspicuously pale, base rounded to cuneate, margin entire, apex rounded to subacute. Inflorescences mostly axillary, 2-5-flowered umbels, sometimes gathered into cymes, to 2 cm. Pedicel to 1 mm. Perianth limb white, pink, or pale purple, to 1 mm. Stamens (1 or)2(or 3). Anthocarp clavate, 3-3.5 mm, 5-ribbed, sparsely puberulent, sometimes with ± sessile glands.
Sunny sites in disturbed areas. Fujian, Guangdong [widespread in Africa, America, Asia, etc.].
This species is often confused with Boerhavia diffusa. It can be most readily distinguished by the lack of multicellular hairs along the leaf margins, consistently pedicellate flowers, and much paler perianth. It differs from B. erecta by the very differently shaped fruit. This is a pantropical, ruderal weed, mainly growing in dry areas.
