What kind of orchid variety is Wudie Chunlan?

    Wudie, also known as Xiaodie, is a Cymbidium goeringii side-petal butterfly flower. When the new shoots first emerge, they are pale purplish-red, then gradually turn purplish-red. The leaf width is medium, with leaves 28--32 cm long and about 0.8-1.1 cm wide, semi-erect leaves, emerald green, without gloss, the leaf surface has longitudinal ridges, the leaf margin serrations are coarse, the leaf edges at the base curl slightly inward, and from the middle to the tip they gradually become flat and spreading. The bracts are deep purplish-red, with coarse dark purple veins. The sepals are oblong, the main petal tightly covers, and the lower half of the side petals is lip-transformed for more than 1/2, with a clear boundary between green and white, marked with red dots; when in full bloom, because the butterfly transformation shrinks and hardens, it pulls the side petals downward, and the petal tips twist backward, just like a butterfly dancing. The cat-ear petals are pale emerald green, marked with purplish-red vein lines; the large round lip hangs down and curls, and the white lip is marked with a red "U" shape.
