Hab. Kilimanjaro, 6000 ft: H. H. Johnston (H. aff. H. ma- 
cranthe, Hochst. in Trans. Linn. Soc. ser. 2, i. p. 849); 
Kilimanjaro, Mochi, 4000-5500 ft., and higher slopes above 
Morang to 10,000 ft.: W. E. Taylor, 1888. 
A fine-looking plant 13-20 inches in height, with the thick 
stem leafy right up to the spike. The leaves have a closely- 
sheathing base 1 inch or less in length, and a spreading ovate or 
ovate-lanceolate blade 38-4 inches long by iJ inch or more broad 
in the larger specimen. The sessile lower bracts resemble the 
leaf-blades in shape, though much smaller in size; they become 
smaller as we ascend the spike, the upper ones being shorter 
than the ovary. The broad spike is 5-6 inches long, and bears ten 
or fewer very large flowers. The dorsal sepal is 1 inch long by 
65 lines broad, with a conspicuous midrib, and six well-marked 
lateral veins united by transverse venules. The lateral sepals 
are 14 lines by 53, similarly veined to the dorsal, the posterior 
side is almost straight. The lateral petals are 14 lines long by 24} 
at their broadest below the middle, acute, 4—5-nerved, and form 
the margins of the dorsal helmet. The lip is 14 inch from its 
insertion to the end of the almost filiform median lobe ; the linear 
base broadens above at the trifureation. The median lobe is 
1 inch long ; the broader lateral ones } inch long by 2 line broad 
below the middle. The recurving spur is 17 lines long, becoming 
subcylindric above the wider base. The ovary is 14 lines. The 
stigmatic processes are 10 lines long, dilated at the ends, as in 
HH. macrantha, in the shape of a foot which is papillose on the 
upper surface. The lower part is adnate to. the anther-cells, 
the canals of which are thin and narrow. 
Is very near the Abyssinian H. macrantha, Hochst.; but 
differs in several minor points, having slightly narrower, more 
spreading leaves, slightly larger flowers with larger sepals, nar- 
rower longer lateral petals, and the labellum hispidulous on the 
upper surface, with an almost filiform median segment. The 
bracts are aiso shorter and more ovate, while the spur exceeds 
the ovary in length.
