the figure associated with something like a swan, inhabits
grasslands or open forests in mountainous regions, standing
0.6-1.2m, with pseudostems 30-70cm in length, and with single leaves
pedately parted. Flower stalks become higher than leaf level.
Spathes are generally green, their limb's tips extend in a tail way,
and appendages curve in an S-letter way in the lower part and then
go straight upward. Bloom time: May-June.
