flexim porrectum, triangulare, viscidio amoto profunde 
bifidum; fovea stigmatica rectangularis. 
Species duae, Africae tropicae incolae. 
Species typica: 7. igulfolia Summerh. 
This small genus resembles very closely some species 
of Tridactyle and, in vegetative characters, certain species 
of Angraecum, all having rather long straggling stems 
with spreading ligulate leaves. The very short inflores- 
cences are also very reminiscent of 7V'ridactyle such as 
T. anthomaniaca (Rehb.f.) Summerh. and 7\. Scottellit 
(Rendle) Schltr., especially those species in which the lip 
is almost entire. Mggelingia differs, however, in the quite 
entire lip, which lacks the thickened basal auricles so char- 
acteristic of T7idactyle, and in the very large rectangular 
viscidium, which is nearly as long as the stipes and longer 
than the pollinia. The genus is best placed next to 7'r- 
dactyle. 
The genus is distributed from the Gold Coast in the 
west to the forests of western Uganda in East Africa, 
being widely spread in the forests of the eastern Congo 
Basin. It is named in honour of Dr. W. J. Eggeling 
who has done so much towards increasing our knowledge 
of the epiphytic orchids of Uganda.
