HO WEST AFRICAN SPECIES OF AMOMUM. 



1863. 



ON SOME NEW SPECIES OF AMOMUM FEOM WEST 



AFEIOA. 



BY Professor OLIVER and DANIEL H ANBURY. 

 (Read before the Linnean Society, April 16, 1863.) 



WE have in preparation a monograph of the West African species 

 of Amomum ; but as there are yet some points to be cleared up, 

 requiring further communication with residents at Sierra Leone 

 and the ports of Liberia and of the Gulf of Guinea, we shall 

 not be in a position to complete it during the present session of 

 the Linnean Society. It appears, however, to be desirable that 

 brief diagnoses of the new species should at once be laid before 

 the Society, and we have accordingly prepared the following. 



Specimens of all the plants described have been received, both 



in the dried state and preserved in fluid, accompanied in most 



Mr. Gustav cases by coloured sketches, from Mr. Gustav Mann, the able and 



Maun. persevering botanical collector to the Eoyal Gardens, Kew. In 



the Museum and Herbarium of this establishment the authentic 



specimens are deposited.
