described in any other of the Rubiaceae (with the possible exception 

 of Dichilanthe Hook.). 



They have the same structure as the colleters, resembling intestinal 

 glands, which in this genus, as in most Rubiaceae, are placed at 

 the inside of the base of the stipules l ) and are also found on 

 the leaf base in Apöcynaceae and in Loganiaceae. They are found 

 in the new species, as in C. flavescens, alternating with the calyx 

 divisions singly or two together; in the latter species they are however, 

 only 7s mm - l° n 8* and have hitherto been overlooked by investigators; 

 in the new species they are well over 1 to 1.5 m.m. in length. 



Perhaps, on closer examination, they will also be found to exist 

 in other Rubiaceae. Obviously they must be interpreted as rudimentary 

 stipules of the sepals.
