识别特征

地生兰,叶褶扇状、矛形,有纵棱,种加词「有条纹的」即指此。早春从假鳞茎萌发,一个假鳞茎可发多枝,两三个月后抽出花茎,开 3 到 7 朵洋红粉色的花,唇瓣有褶皱和深色条纹,白花品种也常见。假鳞茎入药,是传统的止血药「白及」。

栖息环境

草坡、林缘和溪边的沙质土,成丛生长;也广泛栽培于庭院和花坛,是最容易种的兰花之一。

分布

原产日本、朝鲜半岛、缅甸和中国(安徽、福建、甘肃、广东、广西、贵州、湖北、湖南、江苏、江西、陕西、四川、浙江);中国长江流域以南的山坡常见,野生因采挖减少;日本全境栽培常见(日文名「紫兰」)。新加坡无。

花期

4 到 5 月,花期约三周;叶在花后继续长大,秋季枯黄。

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。

洋红的花在阴天或半阴的散射光下最准,阳光下发紫发亮;侧面微距拍唇瓣上的褶皱和条纹。褶扇状的叶在逆光下露出纵棱,是花以外的题材。一丛数枝花茎用大光圈选一枝为主。

适合的摄影风格

半阴处的洋红兰花;褶叶的逆光纹理。

相似物种

小白及(花小,黄白);春兰、蕙兰(叶带状无褶,花绿黄);其他栽培地生兰。

Identification

A terrestrial orchid with pleated, spear-shaped leaves ribbed lengthwise, which the epithet striped refers to. It breaks dormancy in early spring, each pseudobulb sending up several shoots, which in a couple of months bear three to seven magenta-pink flowers with a frilled, dark-striped lip; white forms are common. The pseudobulb is the traditional styptic bai ji.

Habitat

Grassy slopes, forest edge and streamsides on sandy soil, in clumps; widely planted in gardens and beds, one of the easiest orchids to grow.

Distribution

Native to Japan, Korea, Myanmar and China (Anhui, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Shaanxi, Sichuan, Zhejiang); common on hillsides south of the Yangtze, the wild plants reduced by collecting; commonly grown throughout Japan (shiran). Absent from Singapore.

Season and behaviour

April and May, about three weeks in flower; the leaves keep growing after flowering and yellow in autumn.

Photography tips

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

Magenta is truest under cloud or in the diffuse light of half shade and turns purple and glaring in sun; a side macro for the frills and stripes of the lip. The pleated leaves show their ribs against the light, a subject beyond the flower. In a clump of several stems use a wide aperture to pick one.

Photographic styles

Magenta orchids in half shade; backlit texture of pleated leaves.

Similar species

Bletilla formosana (small yellowish-white flowers); spring and faber orchids (strap leaves without pleats, green-yellow flowers); other cultivated ground orchids.
