识别特征

浮叶水生植物,根固定在池沼的泥里,叶漂浮水面,像小睡莲;靠根状茎蔓延成丛。白色的小花直径约 1 厘米,成簇生在叶柄基部,花瓣五枚(有时更多),边缘密生白色流苏状的毛,中心黄色,像一片片雪花浮在水上,英文名「水雪花」由此而来。日本叫「一叶莲」。

栖息环境

池塘、湖泊、沼泽和水田的静水或缓流中,也作水景植物栽培,在佛罗里达逸为小杂草。

分布

原产全球热带地区;中国华南和台湾的池塘有野生,日本本州以南有分布,新加坡的池塘和湿地也有。

花期

6 到 10 月,花早晨开放、傍晚闭合,每朵只开一天;夏末花最密。

拍摄建议

以下为 FilmAnalysis 编辑的拍摄经验,不是资料来源中的内容。

流苏状的花瓣是全部重点,微距正面俯拍,逆光下白毛会发光,减半档。花贴着水面,用偏振镜压掉水面反光,让浮叶的绿成为背景;雨后水珠停在花毛上最好。

适合的摄影风格

水面上的白色雪花;流苏花瓣的微距。

相似物种

莕菜(花黄色,更大);金银莲花这个中文名也被用于本种;睡莲的花大得多。

Identification

A floating-leaved aquatic rooted in pond mud with leaves on the surface like small water lilies, spreading by rhizomes into clusters. Small white flowers about 1 cm across in clusters at the base of the leaf stalk, with five petals (sometimes more) densely fringed with white hairs round a yellow centre, like snowflakes floating on the water, hence the English name. Called one-leaf lotus in Japanese.

Habitat

Still or slow water of ponds, lakes, marshes and paddies, also grown as a water-garden plant; a minor escaped weed in Florida.

Distribution

Native to tropical areas around the world; wild in ponds of southern China and Taiwan, present from Honshu south in Japan and in Singapore's ponds and wetlands.

Season and behaviour

June to October, the flowers opening in the morning and closing by evening, each for a single day; densest in late summer.

Photography tips

These are the FilmAnalysis editors' notes, not content from the sources.

The fringed petals are the whole point: macro straight down, with backlight making the white hairs glow at half a stop under. The flower sits on the water, so a polariser kills the surface glare and lets the green of the floating leaves be the background; water drops caught in the fringe after rain are best of all.

Photographic styles

White snowflakes on water; macro of fringed petals.

Similar species

Fringed water lily, Nymphoides peltata (yellow, larger); the Chinese name gold-and-silver lotus is also used for this species; water lilies are far larger.
