The name C. acuminatum is preoccupied, and specimens received from Berlin, 

 named C. acuminatum by Dr. Schumann, do not belong to this species, but to C. 

 AdalincB, K. Schum., so that I am uncertain what plant is intejided by C. acumina- 

 tum, K. Schum., the description given being insufficient. Specimens f rom Cameroons 

 and French Congo are referred to C. acuminatum, K, Schum., by Schlechter (West-afr. 

 Kautschuk Exped. 309), some of whreh probably belong to C. Adalince, K. Schum.
