"Stem l-lg ft. high. Leaves sh(\athing, alternate, bifarious, their 

 sheaths entire, 1 in. long; leaves gradually larger upwards, 3-7 in. long. 

 Flowers terminal, 3-4, each subtended by a pale green foliaceous per-

 shaped like the hood of a cobra. Lip not articulated with the spur, 

 which merely forms the tubular base of the labellum. Flowers in the
