识别特征

多年生草本,有根状茎,叶像芭蕉,丛高 1.5 到 3 米。与大多数蝎尾蕉直立的花序不同,它的花序下垂,长可达 1 米,由一列鲜红色、尖端黄绿的船形苞片两列交错排成,像一串龙虾的钳子或一只只鹦鹉嘴,所以叫「金鸟赫蕉」「垂花蝎尾蕉」「假天堂鸟」;真正的花小、黄绿色,藏在苞片里。苞片蜡质,持续数周。

栖息环境

热带雨林的林缘和湿润处,喜高温多湿;是热带公园和度假村最常见的观花植物之一,也作切花。

分布

原产南美洲亚马逊流域(秘鲁、玻利维亚、哥伦比亚、委内瑞拉、厄瓜多尔)到中美洲(萨尔瓦多、哥斯达黎加),归化于波多黎各,世界热带广泛栽培;新加坡的公园和植物园极常见,华南(云南西双版纳、广东、海南)栽培,日本仅温室。

花期

热带全年开花,雨季最盛;一串花序可持续一个多月。

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。

下垂的红黄串是现成的垂直线条,竖幅、平视,深绿叶做背景;苞片蜡质反光,侧光拍质感、柔光拍颜色,红色减半档。逆光下苞片边缘的黄绿透光。微距拍苞片里藏着的小花。太阳鸟和蜂鸟(原产地)来访,1/1600 秒。

适合的摄影风格

深绿前的下垂红串;蜡质苞片的侧光。

相似物种

黄苞蝎尾蕉(Heliconia psittacorum,直立、小、橙色);金嘴蝎尾蕉(Heliconia bihai,直立);旅人蕉和鹤望兰(花序形状不同)。

Identification

A rhizomatous perennial with banana-like leaves in clumps 1.5–3 m tall. Unlike most heliconias, whose inflorescences stand upright, its inflorescences hang, up to a metre long, a row of bright red boat-shaped bracts tipped yellow-green in two alternating ranks like a string of lobster claws or parrots' beaks, hence hanging lobster claw and false bird of paradise; the true flowers small and yellow-green inside the bracts. Waxy bracts lasting weeks.

Habitat

Rainforest edge and damp places in heat and humidity; one of the commonest flowering plants of tropical parks and resorts, also a cut flower.

Distribution

Native to the Amazon basin of South America (Peru, Bolivia, Colombia, Venezuela, Ecuador) and Central America (El Salvador, Costa Rica), naturalised in Puerto Rico and grown throughout the tropics; very common in Singapore's parks and botanic gardens, grown in southern China (Xishuangbanna in Yunnan, Guangdong, Hainan), glasshouse-only in Japan.

Season and behaviour

All year in the tropics, most in the rains; one inflorescence lasts over a month.

Photography tips

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

The hanging red and yellow string is a ready vertical line, in a portrait frame at eye level with dark green leaves behind; the waxy bracts flare, so side light for texture and soft light for colour, half a stop under for red. Against the light the yellow-green edges glow. Macro for the small flowers hidden in the bracts. Sunbirds, and hummingbirds in its homeland, visit at 1/1600 s.

Photographic styles

A hanging red string before dark green; waxy bracts in side light.

Similar species

Parrot heliconia, Heliconia psittacorum (upright, small, orange); Heliconia bihai (upright); traveller's palm and bird of paradise (differently shaped inflorescences).
