317 第 4 期 刘仲健等: 金蝉兰,中国云南兰科一新种
附生植物, 假鳞茎椭圆状卵形或狭卵形,长 5～
10 cm ,宽 3～5 cm ,包藏于叶基内。叶 6～11枚,带
状,长 80～90 cm ,宽 2. 0～3. 5 cm ,深绿色, 下部有
关节。花葶近直立,长 90～100 cm, 约具 10枚鞘;鞘
长达 15 cm ,宽达 2. 5 cm ; 总状花序长 33～40 cm,
其 8～10 朵花; 苞片卵状三角形, 长 3～5 mm, 宽
2～4 mm; 子房连柄长 1. 5～3. 8 cm , 绿色; 花直径
约 7 cm ;萼片绿黄色,花瓣黄色,唇瓣黄绿色并在上
面具深黄色线纹, 全部无紫点或紫条纹;中萼片狭倒
卵状矩圆形, 长 4～6 cm , 宽 1. 3～1. 6 cm, 先端急
尖;侧萼片斜歪, 狭矩圆形,长 3. 4～5 cm, 宽 1. 2～
1. 5 cm, 先端急尖; 花瓣镰刀状线形, 3. 7～5. 6 cm,
宽 0. 6～0. 9 cm ,先端急尖;唇瓣近椭圆形, 长3. 0～
3. 1 cm ,宽 1. 7～1. 8 cm , 3裂,与蕊柱基部合生约长
3 mm ;侧裂片直立,半圆形, 沿脉纹具细短柔毛,边
缘强烈皱波状并具长金黄色缘毛;中裂片卵圆形,长
8～10 mm,宽 9～10 mm,外弯, 边缘强烈波状; 唇盘
上具 2条纵褶片, 褶片上密生长毛,在两褶片之间尚
有 1行长毛;蕊柱长 3～3. 8 cm, 弧曲, 基部腹面具
疏短毛,边缘具翅;花粉团 2个。花期 9～10月。
本新种与西藏虎头兰 Cymbidium tracyanum
L. Castle 有亲缘关系,但本种花较小,直径仅 7 cm ,
黄色,没有紫点或紫斑,唇瓣侧裂片边缘强烈皱波状
并具金黄色缘毛,易于区别。而西藏虎头兰子房连梗
明显长于蕊柱, 蕊柱仅上半部边缘具翅。区别明显。
Cymbid ium gaol igongense Z. J. L iu et J. Y.
Zhang is descr ibed as a new species based on the
plants col lected from the Goul ig ong M ountains,
near Boshan of Yunnan, China. Some plants of
this new species have been transplanted in Shen-
zhen City Wutong shan Nurseries. T he new species
is similar to Cymbidium tr acyanum L. Cast le, from
which it differ s by having , yellow f low ers ca. 7 cm
across, and lateral lobes of the lip st rong ly crisped
and go lden-ciliate on the margins.
