        Published in Aiton: Hortus Kewensis ed. 2, 5: 198. 1813. Basionym is Satyrium repens Linnaeus 1753, published in Species Plantarum 2: 945. 1753.

        Goodyera repens is widespread in the Minshan and also common in Huanglong where it grows usually in moss in open shade of forest and dense scrub but in the Huanglong valley also in brighter conditions in open scrub. The altitude range in the park is from 2300-3500 m. The plant forms tiny leaf rosettes close to the ground with a diameter of 3.5-5 cm, often occurring in more or less dense groups. The leaves are usually intensively marked with whitish- green lines and stripes and they are persisting during the winter. The flower stems are 6-12 cm tall and carry 4-16 pure white flowers of 4-5 mm diameter.

        植株高10-25厘米。根状茎伸长,茎状,匍匐,具节。茎直立,绿色,具5-6枚叶。叶片卵形或卵状椭圆形,长1-2厘米,宽5-15毫米,上面深绿色具白色斑纹,背面淡绿色,先端急尖,基部钝或宽楔形,具柄,叶柄长5-10毫米,基部扩大成抱茎的鞘。花茎直立或近直立,被白色腺状柔毛,具3-5枚鞘状苞片;总状花序具几朵至10余朵、密生、多少偏向一侧的花,长4-15厘米;花苞片披针形,长5毫米,先端渐尖;子房圆柱状纺锤形,连花梗长4毫米,被疏的腺状柔毛;花小,白色或带绿色或带粉红色,半张开;萼片背面被或多或少腺状柔毛,具1脉,中萼片卵形或卵状长圆形,长3-4毫米,宽1.2-1.5毫米,先端钝,与花瓣粘合呈兜状;侧萼片斜卵形、卵状椭圆形,长3-4毫米,宽1.5-2.5毫米,先端钝;花瓣斜匙形,无毛,长3-4毫米,宽1-1.5毫米,先端钝,具1脉;唇瓣卵形,长3-3.5毫米,基部凹陷呈囊状,宽2-2.5毫米,内面无毛,前部短的舌状,略外弯;蕊柱短,长1-1.5毫米;蕊喙直立,长1.5毫米,叉状2裂;柱头1个,较大,位于蕊喙之下。

        小斑叶兰广泛分布于四川岷山以及黄龙保护区,通常生长在海拔2300-3500米的林中或者茂密灌丛中的苔藓丛中,但在黄龙沟小斑叶兰也可生长在开阔灌丛中。小斑叶兰的叶片很小,形成直径一般为3.5-5厘米的莲座状,贴生地表,通常在生长繁茂的群体中莲座状叶更明显。叶片上通常具白绿相间的条纹,即便是在冬季小斑叶兰也能生长得很好。小斑叶兰植株高一般为6-12厘米, 总状花序, 花4-16朵,纯白色,花的直径通常是4-5毫米。花期:7-8月。
