3-lobed ; lobes linear ; front lobe 7—8 lin. long; spur filiform, clavate 
at the apex, 10 lin. long. Stigmatic processes triangular-attenuate, 
laterally compressed, as long as the anther channels. Rostellum small,

Nile Land. Abyssinia: Samen; Woina, near Debra Eski, 6900-7500 ft.,

Only known to me from the original description, in which it is compared with H.

6la. Habenaria Rive, Kränzl. Orch. Gen. et Sp. 238. Plant 
very robust, 4 ft. high. Stem leafy. Leaves 6, oblong-lanceolate, 
acute, 1 ft. long, 2 in. broad, decreasing upwards. Spike rather short, 
‘dense, many-flowered. Bracts exceeding the flowers, ovate-lanceolate, 
acuminate, # in. long or the lower longer, upper hairy. Pedicels 
7 lin. long. Flowers 3 lin. long. Dorsal sepal cucullate, oblong, acute, 
lateral subobliquely ovate, more than twice as broad as the dorsal, 
setoseat the margin. Petals ovate, acute, nearly simple, but extended 
in front into an acute angle, as if indicating a nearly suppressed front 
lobe. Lip as long as the petals, simple, ovate-lanceolate, acuminate, 
with a broad thickened line or callus from base to apex; spur filiform, 
inflated at the apex, 8 lin. long. Column punctate-scaberulous through- 
out ` stigmatic processes long, arcuate, cochleate at the apex; anther 
‘channels as long as and parallel to the stigmatic processes ; rostellum 
linear, acute, reflexed, a little longer than the anther.

A very distinct species, only known to me from the original description. 
64, Habenaria insignis, Rolfe. The name Habenaria insignis 
having been applied by Schlechter to a South African species (Engl. 
Jahrb. xx. Beiblatt, 32), I propose re-naming the present one H. 
‘mirabilis, Rolfe.
