later described sorts to earlier drawings, is an uncertain standard by 



which to judge of the synonyms. 



The brevity of the earlier diagnoses, as those of Linnaeus, prove this 

 assertion. I transcribe in part what is said in the * Species Plantarum * 

 of Willdenow (iv. 11. 645), by which it may be readily judged concern- 

 ing the brevity, and the numberless plagiaries. I merely remark, that 

 from what is now required in Systematic Botany, no one would be able 

 to determine the genus Pandanus from this generic diagnosis, and that 

 the characteristics of the species apply equally to any of them. The
