ON COmOCHLAMYS, A WEST AFRICAN GENUS OF 



ACANTHACE^. 



Br S. Le M. Moore, F.L.S. 



(Tab. 182.) 



In a collection of Angolan plants made by M. Soyaux under the 

 auspices of the German African Society, which has recently been sent 

 to Kew from Berlin, there occurred a species of Coinochlamys, a rather 

 curious genus, some time since established in manuscript by the late 

 Dr. Anderson, but first characterised by Mr. Bentham in the recently 

 published part of the *' Genera Plantarum." Unfortunately the type- 

 specimen — one of Mann's Bagroo River discoveries — is so fraguien- 

 tary that Mr. Bentham was not able to give a full generic characteri- 

 sation, and it is partly on this account, and partly because the genus 

 is sufficiently peculiar to warrant special notice, that I have drawn up 

 the following emendation, with diagnoses of the two known species 

 and a few remarks on affinity and noteworthy points of structure.
