EUCOFFEA HOOK. F. 29 



Geographical Distribution: — East African Tropics; Mozambique. 



History: — The seeds of this species first appeared on the German 

 southeast African market in 1893 and on a small island, belonging 

 to Portugal, called Ibo which is about 12° South Latitude and from 

 which it derives its name "Ibo Coffee." Specimens of the plant 

 were sent by Prof. Henriques and Inspector Moller to the Botanical 

 Museum in Berlin. It is mentioned in the Notizbl. d. Kgl. Bot. 

 Mus. 5 (1895) but was not described until 1897. The beans ap- 

 pear to be immature because of their inferior size and the slightly 

 thickened endosperm. 



Use: — It has been recently taken in cultivation in its native local- 

 ities as a substitute for C. arabica L.
