ANONACER. 
THE collection contains a remarkable number of curious and 
interesting ınembers of this family. There are two new genera, 
Dennettia and Alphonseopsis. The former belongs to the tribe 
Xylopiee and is allied to Melodorum, the latter is allied to the 
Indian genus Alphonsea. Uvaria obanensis sp. nov. is a showy 
plant with large flowers generally in fascicles of three ; and Uvaria 
anonoides sp. nov. is closely allied to U. latifolia Scott Elliot. 
There are good specimens of Pachypodanthium Staudtii Engler 
& Diels, which has not been previously recorded for Nigeria. 
Unona obanensis sp. nov. is closely allied to U. hirsuta Benth. ; 
and U. Millenii Engler & Diels was previously known only from 
Lagos.  ' 
There ‚are four species of Monodora and two species of 
Tetrastemma ; one of the latter is probably T. Solheidii De 
Wild., previously known from the Congo, the other has much 
larger flowers (4-5 cm. long), but we await better material.
