his autem angustioribus et oblongo-ligulatis ; petalis sepalis sub-

alibus brevibus rotundatis in facie superiore pubescentibus, 
carina intermedia lamelliformi in dentem obtusum in basi lobi

The single leaf present resembles those of A. pachyglossa, 
Reichb. f., but is less linear, it is 8 inches long by 1} inch at its 
greatest width. The fleshy flower-spikes are 3-4 inches long and 
bear a few short similar branches. The numerous flowers are 
much larger than in A. pachyglossa, but similar in general 
appearance. The sepals and petals are thick, especially on the 
veins, with a thinner subtransparent marginal portion ; the 
dorsal sepal is 5 lines long by 24 broad above, the lateral ones 
are similar but narrower (2 lines broad) and oblong ligulate ; the 
lateral petals are also similar in length, but more spathulate in 
shape and 1# line at their broadest. The lip is 41-5 lines long, 
rotundly gibbous at the base; the lower lobes are short and 
rounded, pubescent above and separated by a central lamelliform 
keel which ends in a bluntish tooth at the base of the median 
lobe, which is fleshy, pentagonal, and obtuse, 2 lines long, and as 
broad, with the upper surface and margins covered with large 
irregular papilla. The short thick column is about 1 line long. 
Differs from A. pachyglossa, Reichb. f., collected by Hildebrandt 
(no. 1991) on the mainland near Mombasa, in its much larger 
flowers, about twice the size, the greater similarity in width 
between sepals and petals and the very rounded gibbous base of 
the lip, which in A. pachyglossa forms a marked conical pro- 
jection.
