|Gastrodia elata is a
chlorophyll-lacking saprophytic orchid plant inhabiting wood floors,
making big oblong tuberous roots of around 10cm in length, gradually
becoming hollow as the terrestrial part grows up. Flower stalks,
0.6-1m in height, tinge yellow-red, wear some membranaceous ramenta.
Flowers, many in number, are yellow-brown and bloom in a racemose
manner in June-July.
