107. H. ecaudata, Krénzl. in Engl. Pfi. Ost-Afr. C. 152. Plant 
very large and tall, the part seen over 2 ft. high. Leaves ovate-oblong, 
obtuse, 5 in. long, 2 in. broad, decreasing upwards into the bracts. 
Racemes about 7-flowered. Bracts oblong, acuminate, 4—2 as long as 
the ovary. Flowers among the largest of the genus. Dorsal sepal 
cucullate, acute; lateral oblique, longer than the dorsal, cuneate, 
laterally apiculate; base united with the base of the lip and the 
stigmatic processes. Petals bipartite ; posterior lobe linear, as long as 
the dorsal sepal and strongly agglutinated with it; anterior lobe very 
narrowly linear, more than twice as long as the posterior, recurved 
like a horn. Lip tripartite from an entire, linear base ; lobes linear ; 
side lobes very long, as long as the anterior lobe of the petals; front 
lobe one-third shorter than and twice as broad as the side lobes ` spur 
entirely absent. Stigmatic processes cochleate at the apex. Anthers 
very tall, acute ; channels very long, straight, as long as the stigmas.

Remarkable for the absence of a spur, also in the shape of the rostellum, but said 
to be allied to H. cirrhata, Reichb. f. I have not seen it.
