purple. Upper sepal orbicular, apiculate, with 3 to 5 prominent 

 veins, about 1.5 x 1.3 cm. Lateral sepals united into a doubly api- 

 culate structure, the apiculations being about 2.5 mm. apart, each 

 half of the double sepal having a prominent mid-vein with forking 

 and often anastomosing lateral veins, the double sepal orbicular, 

 about 1.2 cm. each diameter. Lateral petals slightly longer than 

 the sepals, about 1.6 cm. long, 3 mm. wide, linear elliptic, rounded at 

 the apex, the base rounded on the upper side. Lip 15 cm. long by 

 I cm. vertical diameter, general profile obovate, veins variously 

 forking and anastomosing, puberulent, and more or less glandular 

 below, exteriorly, and also laterally at the base inside. Midway on 

 each side of the orifice a flap about 3 mm. long and widely obtuse is 

 folded into the cavity of the lip; the orifice is circular, about i.i cm. 

 in diameter. The ovary is about 2.5 cm. long, elliptic, tapering to a 

 peduncle below, obtusely angled, minutely glandular-puberulent. 

 Stigma with an orbicular and somewhat concave disk about 3 mm. 

 in diameter; staminodium expanded into a flat ovate structure about 

 6 mm. long and 4 mm. wide, arching or ascending over the stigma, 

 obtuse or sub-cordate at the base and retuse or with a recurved tip 

 at the apex. Stamens with flat, obtusely ovate appendages extending 

 dorsally over the anthers, free from them, but of about the same length. 

 Capsule erect, 2.5 cm. long, 1.5 cm. thick, obtuse at the apex, tapering 

 into a slender peduncle 1.2 cm. in length, sometimes remaining at the 

 apex of the defoliated stem during the next season.
