476 Floristik und Systematik der Phanerogamen. 



The author gives a brief historical sketch oi the gradual discovery 

 of the different species of this genus and also a description of the chief 

 characters of Corylopsis. The new species (C. sinensis) is most closely 

 allied to C. spicata, but differs in tlie stipules of the flov/ering branches 

 being broader than long, in the leaves being broadest above the middle, 

 in the orbicular petals being suddenly narrowed into a distinct claw, 

 and in the yellow anthers and white seeds. A number oi other undescri- 

 bed Chinese and Indian species of the genus will be published in 

 the next part of Hooker's „Icones Plantarum".
