316 RUBIACE2E. 



XC1V. BUBIACEjE'. 



Stamens inserted into the sympetalous corolla, rarely free from it. Ovary inferior, rarely 

 free above its base, syncarpous. Embryo usually included in albumen. — Leaves mostly quite 

 entire, whorled: one pair in the whorl developed, the rest (the stipules) minute, or all 

 developed. 



Powerful action upon the nervous system is the most remarkable property in this Order, 

 which affords Coffee, Cinchona, and Ipecacuanha. Of Quinquina, only the spurious barks 

 called " Quinquina Piton," or " China caribsea," occur in the West Indies (Exostemma flo- 

 ribundum and brachycarpum) , while the genuine white Ipecacuanha (Richardsonia . cabra) 

 is a native of Jamaica. Coutarea speciosa is used as an emetic in Trinidad (Lockh.) ; 

 Ckiococca racemosa affords the resolvent root of Cainca : and Spigelia anthelmia, though 

 poisonous, is a reputed anthelmintic. A yellow pigment is extracted from Morinda Eoyoc 

 and citrifolia, a red one from Oldenlandia umbellata. Timber trees in this Order are : 

 Chimarrhis cymosa ; Guettarda argentea, an excellent timber-tree (Wils.) ; Chione glabra ; 

 Ixoraferrea, a hard wood, used for axe-handles (Imr.).
