author concludes that its true position is in the Lüiaceae next to 

 the genus Dracaeiia, from which it cannot be distinguished unless 

 Dracaena be divided up into two genera characterised by a struc- 

 tural difference in their flowers, these two genera being Dracaena 

 and Pleoiiiele. The author gives a historical account of the latter 

 and his reasons for adopting the name. Histories of the genera 

 Satisevieria , Cordyline and Taetsia are also given, followed by a 

 Synopsis in which are the distinguishing characters of the genera.
