识别特征

睡莲科第二大的植物。叶巨大,直径可达 3 米,边缘上翻成圆盘,背面有网状的粗叶脉和刺,叶柄沉水、长 7 到 8 米;叶的浮力惊人,重量均匀分布时可承载几十千克。花直径达 40 厘米,第一夜开白色花、散发浓香,吸引金龟子前来,然后合拢把甲虫关在花内一夜;第二天傍晚再开时已变成粉红,放出沾满花粉的甲虫。原产圭亚那和亚马逊河流域,是圭亚那国花,巴西叫「Vitória-Régia」。19 世纪英国的水晶宫温室借鉴了它叶脉的结构。

栖息环境

亚马逊流域的河湾和洪泛湖的静水;只能在热带露地或温室的大水池中栽培,是热带植物园的招牌。

分布

原产热带南美洲(圭亚那、亚马逊盆地);东亚全部是栽培:新加坡植物园和滨海湾花园的水池常年有,华南的植物园(广州、厦门、西双版纳)夏季展出,北方和日本的植物园温室或夏季水池(日文名「オオオニバス」,常办「让孩子坐在叶上」活动)。

花期

热带全年,北方和日本 7 到 9 月;每朵花只开两夜,第一夜白、第二夜粉。

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。

叶是主题:俯拍成片的圆盘和上翻的边缘最图形化,有人或孩子坐在叶上才看得出尺度(只在植物园组织的活动里)。花在傍晚开放,第一夜白、第二夜粉,守着傍晚的水池拍两种颜色。叶背的刺和网状脉要翻开的叶或边缘上翻处的微距。水面倒影配圆盘,低角度。

适合的摄影风格

俯拍的巨大圆盘;傍晚白与粉的花。

相似物种

克鲁兹王莲(Victoria cruziana,叶缘更高、耐凉,北方更常见);玻利维亚王莲(Victoria boliviana,最大,2022 年才描述);芡实(叶大有皱、无上翻边缘)。

Identification

The second largest plant of the water-lily family. Huge leaves up to 3 m across with upturned rims like trays, the underside ribbed with a network of thick spiny veins, on submerged stalks 7–8 m long; the pads are astonishingly buoyant and carry tens of kilograms when the weight is spread. Flowers up to 40 cm across open white and strongly scented on the first night to draw scarab beetles, close over them for a day, and reopen pink the next evening to release them dusted with pollen. Native to Guyana and the Amazon basin, the national flower of Guyana, Vitória-Régia in Brazil. The Crystal Palace glasshouse of nineteenth-century Britain borrowed the structure of its leaf veins.

Habitat

Still water of river bays and flood lakes in the Amazon basin; grown only in large pools outdoors in the tropics or under glass, the signature plant of tropical botanic gardens.

Distribution

Native to tropical South America (Guyana, the Amazon basin); entirely cultivated in East Asia, in the pools of the Singapore Botanic Gardens and Gardens by the Bay all year, in southern Chinese botanic gardens (Guangzhou, Xiamen, Xishuangbanna) in summer, and in glasshouses or summer pools in northern China and Japan (ōonibasu, where gardens often sit children on the pads).

Season and behaviour

All year in the tropics, July to September in the north and Japan; each flower lasts two nights, white the first and pink the second.

Photography tips

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

The leaf is the subject: from above, the array of trays and upturned rims is most graphic, and only a person or child sitting on a pad shows the scale (only at a garden's organised event). The flower opens at dusk, white one night and pink the next, so wait by the pool at dusk for both colours. The spines and network of veins underneath want a macro on an upturned leaf or rim. Reflections and trays from low.

Photographic styles

Giant trays from above; white and pink flowers at dusk.

Similar species

Santa Cruz water lily, Victoria cruziana (higher rims, tolerates cool, commoner in the north); Victoria boliviana (the largest, described only in 2022); Euryale ferox (large puckered leaves, no upturned rim).
