Lissochilus stylites is a species which was originally 
described by the late Professor Reichenbach in 1878 from 
material collected by Dr. Schweinfurth near Munsa in the 
Monbuttu Country, and was then stated to be allied to 
L. arenarius, Lindl., but to be distinguished by the 
presence of a pair of styliform capitate calli in the throat 
of the lip. A plant collected by Mr. Mechow in Angola 
was subsequently referred to the same species, as a form that 
differs only in having a shorter crest. Another plant, 
which had been received by the Hon. Mrs. Foley from a 
friend at Ikom, on the Cross River, Southern Nigeria, with 
the information that it grows in hot and moist localities, 
flowered in her collection at Packham, Fordingbridge, 
Hants, in June, 1909. This plant was exhibited at a meet- 
ing of the Royal Horticultural Society and supplied the 
material from which our plate has been prepared. This 
Nigerian Lissochilus is considerably larger in all its parts 
Octoser, 1911.
