tibus; sepala quam petala longioribus, oblongo-ligulatis, subacutis, petalis ovalibus, 
obtusis; labello semipollicari, parte inferiore et majore trapezoideo, superiore tri- 
angulari-ovato obtuso, dense tomentoso ; calcare brevi obtuso ; columna erassiuscula. 
Peduncle 19-21 in. long, clothed at the base with a sheathing-leaf 21 in. long, which 
also includes two young foliage-leaves; 14 line in thickness an inch above the base, 
terete below, becoming longitudinally grooved above when dry, bearing one bract at 
about a third the way up. Bract ? in. long, margins connate for 1 line at the base, 
then rapidly receding to form the upper free triangular part, which, however, is closely 
applied to the peduncle. The lax secund raceme is about 9 in. long; the lower bracts 
are 5 lines long, the size decreasing upwards. The short pedicels are about 2 lines long. 
The oblong ligulate sepals are longer and much darker than the petals, 3-nerved, 8 lines 
long, 13 broad, but narrower at the base; petals 53 by 2 lines, with a prominent midrib 
and two upwardly branching lateral veins. The lower part of the lip, when flattened, 
is trapezoid (the sides naturally ascend), 4 lines long by 2} wide in the lower half, then 
slightly widening upwards to 3 lines at the two rounded angles; the apical lobe is 2 lines 
long by 1? broad at the base, and has its upper surface covered, except near the margin, 
with a matted tomentum arising from the veins and passing down the three median nerves 
a short way into the lower part. The spur is blunt, swollen and rounded at the tip, 
24 lines long. The column is 2? lines long, 1 broad.

The structure of the flower recalls that of a group of Cape species including Hulophia 
lamellata, Lindl., which it somewhat resembles, but is distinguisbed by the marked 
difference in size between the sepals and petals, and the shape of the apical lobe of 
the lip, which in £. lamellata is much larger, quadrate, and has a longer tomentum ; 
the inflorescence in that species is branched and the bracts are longer.

Lindley described this species from a West Tropical African plant (Barter, no. 1488), 
but it seems common in the East.

Reichenbach (Otia Bot. Hamb. p. 75) makes Hildebrandt’s plant, no. 1950, Mombassa, 
1876, the same species; it differs slightly from the other East Tropical specimens seen 
in its acuminate lateral sepals, and in having small warts on the surface of the labellum 
in front of the pairs of calli. The lamelliform calli vary in the different specuneris 
in shape, in the character of the apex, which may be crenate or emarginate, and in their 
more or less erect position on the veins.
