patentibus oblique ovatis subacutis 5-nerviis, quam illud lati- 
oribus ; petalis lateralibus usque ad basin bipartitis, parte 
postica lineari-falcata acutiuscula, antica subequilonga sed 
angustiore et lobis labelli lateralibus simili; labello 3-partito, 
lobo medio late lineari 3-nervio acutiusculo, lobis lateralibus vix 
filiformibus subequilongo ; calcari sesquipollicari subtenui apice 
acuto; processibus stigmaticis subrectis clavatis anthere canali-

gulari supra antheram rotundatam elongato; ovario anguste 
6-alato. 
Hab. Between Unyamwezi and coast: W. E. Taylor, 1887. 
About 20 inches high, with a small obovoid tuber ? inch long 
and two large suborbicular radical leaves nearly 3 inches across. 
Above the basal leaves the angular stem bears a number of 
distant subpatent bracteiform leaves more or less lanceolate in 
shape and 1 inch or more in length below, shorter above, and 
passing into the lanceolate acuminate floral bracts, which are 
shorter than the narrowly 6-winged ovary. The dense spike is 
24-4 inches long. The flowers are of a fair size, measuring 13 
lines from point to point of the lateral sepals. The dorsal sepal 
is 5 lines long by 23 broad, the rather larger oblique and more 
acute spreading lateral sepals 6 by 3 lines. The lateral petals 
are split down to the base; the narrow falcate posterior segment 
is 43 lines long by § line broad, the anterior one is almost fili- 
form, 5 lines long by 3 line broad, resembling the lateral lobes of 
the lip. The lip measures 7 lines from the mouth of the spur to 
the tip of the median lobe, which is 5} lines long by 14 broad, the 
very narrow lateral lobes are equal to it in length. The narrow 
spur is 13 inch long, with a rather long pointed tip. The horizontal 
and club-shaped stigmatic processes are 13 linelong. The ovary 
is nearly # inch long. 
In Kraenzlin’s arrangement of the genus in Engl. Jahrb. xvi. 
p- 52, this plant falls in the Section 3, Ceratopetale, nearest 
HI. Welwitschii, Reichb. f., as the segments of the lateral petals 
are of almost equal length, while the thickened club-shaped 
stigmatic processes are only slightly longer than the anther- 
canals. It, however, differs considerably from this and its near 
allies in its large broad pair of radical leaves, and larger flowers, 
with a long spur, in which it resembles H. Elliotii, Rolfe, from 
Madagascar. It resembles very closely in habit and characters of 
stem and leaf H. stylites, Reichb. f. & Moore, from Kilimanjaro,
