The fact that Zygia and Bucida, two of Patrick Browne's genera, have 

 been omitted from the excluded list of genera shows how a list of this sort, 

 prepared by a few men largely by personal preference and without regard 

 to priority of publication, can become unsatisfactory in practice. Zygia is 

 the oldest name for the genus usually called Pithecolobium Mart., and 

 Bucida is the oldest name for the more familiar TerminaJia L. They are 

 in the same case as Ichthyomethia, Chytraculia, and other genera of Pat- 

 rick Browne which are excluded. Moreover, the retention of Zygia is com- 

 plicated by the fact that the name has been used for an African genus 



gnized 



the name for a section in the genus Albizzia Durazz.
