Of them one time was occurred in differentiation of sepal primordium, and itmight be the reason of forming the simple layer of sepal.

其中花瓣原基的分化只进行1次，这是形成单轮花瓣的原因。

Scape usually longer than leaves, with 2-3 flowers each with 1bract, floral bract hooded, broad-ovate, as long as ovary, blunt and usually 3-lobed at apex; flower green-yellow, dorsal sepal white with yellow-green veins and green base, elliptic, 4-4.5cm long, short-pointed at apex, keeled on back, pubescent at base inside, petals very long, pendulous, twist, linear, 8.5-12cm long,6mm wide in middle; lip reversed helmet-shaped, longer than dorsal sepal, with claw almost as long as hood, side lobes inflexed, auricles large and nearly broad-triangular; staminode obcordate; stamens with thick and short filaments; ovary rostrate, 5.5cm long, glabrous.

Its results showed that ratio of length to width of petal and sepal and the degree of flat of achene within population were characterized as the most stable characters and gradually increased with the increase of latitude.

结果表明，居群内，瘦果扁平度、花瓣长宽比、萼片长宽比变异最为稳定，居群间，这3个繁殖器官的相对性状呈现随着纬度的增加逐渐增大的趋势，并且随纬度的增加，核型不对称系数呈现不断增加而染色体总长不断减小的趋势。
