acutis bracteiformibus distantibus ; inflorescentia pauciflora 
H. crocee, bracteis ovatis acutis ovario pedicelloque tenui circiter 
duplo brevioribus ; floribus inter minores; sepalo dorsali late 
ovato acuto cucullato, lateralibus reflexis (?), a basi brevi angus- 
tissima lineari-oblongis, sub apice acuto inwqualiter plicato vix 
angustatis ; petalis lateralibus falcatis acutis, ad sepalum dorsale 
adnatis, gale latera eflicientibus; labello ligulato obtuso supra 
basin utrinque obtuse angulato marginibus valde reflexis, caleari 
tenui recto basin versus vix ampliato ovarium cum pedicello sub- 
zquante ; processibus stigmaticis crassiusculis compressis a basi 
tenui ovato-subrhomboideis; anthere canalibus ascendentibus 
latis truncatis quam processus paullo longioribus, rostello 
triangulari ad antheram erectam sublongiorem valde apiculatam 
parallelo. 
Hab. Unyamwezi to coast: W. E. Taylor, 1887. 
The very slender stalk measures 1 foot below the inflorescence, 
and bears five linear upwardly narrowing acute bracteifurm leaves 
(1-11 inch in length) with a sheathing base, separated by long 
internodes. The short corymbose raceme is 1} inch long, the 
ovate acute bracts 4-5 lines. The hooded dorsal sepal measures 
41 by 3 lines; the shortly stalked lateral sepals (5 by 14 line) 
are 5-nerved in the lower two thirds of their length, and become 
slightly narrower in the upper tiird towards the unequally 
plicate acute apex. The 3-nerved lateral petals are 4 lines long 
by 3 line broad, and adherent to the dorsal sepal, helping to form 
the sides of the hood. The narrow lip (44 by scarcely { line) is 
slightly angled on either side abuve the base, and has the sides 
strongly deflexed ; the thin spur is 7 lines long, equal in length 
to the ovary with its thin pedicel. The short (14 live) stigmatic 
processes consist of a vertically compressed subrhomboid anterior 
part on a thin Stalk. The erect strongly apiculate anther is 
21 lines long, the triangular rostellum which stands in front and 
parallel with it is just over 2 lines, the broad truncate canals 
project slightly beyond the stigmatic processes. 
Resembles H. crocea, Schweinf., in habit, but has larger flowers 
aud also differs in the shape of its stigmatic processes, in its 
apiculate anther, and other details. Approaches very nearly to 
H. Buchananiana, Kraenz. in Engl. Jahrb. xix. p. 247 ; but differs 
in having the lip longer and angled above the base, the spur 
scarcely inflated, while the huge anther-canals and rostellum 
are also distinguishing characteristics.
