Eulophia congoensis CoGN. in Fourn. des Orchid., VI, p. 155 (1895): 
he beautiful Eulophia figured on our annexed plate was introduced 
from Congo by Messrs Linpen, L’HorricutturE INTERNATIONALE, and 
# flowered for the first time at their establishment. 
It is closely allied to E. guwineensis R. Br., a species which inhabits various 
districts of central and specially western tropical Africa; but the colour is quite 
different in the two species; moreover, the latter has notably narrower and more 
shortly petiolate leaves; the sepals and sepals strongly twisted, instead of flat ; 
the front lobe of the lip ovate, acute at the apex and undulate-crenulate along 
the margin, with the spur more or less bent upwards, and the column curved
