These new Oriental or Oceanic representatives of the group, 

 very like Voyrias in aspect, except tbat tbe tube of the corolla is 

 sliort and inconspicuous, must, however, be referred to a different 

 division of the Order as arranged by Grisebach, namely, to his 

 subtribe ChironiecB ; for a principal character of the new genus 

 is that the anthers are not merely destitute of connective, but the 

 twQ ceUs are actually conflucut into one, which opens at tbe apex 

 by an ample foramen. As is not unusual iu Chiro?iiecdy the large 

 placentsD are more or less united in the axis ; in one species, and 

 probably in the otlier as well, the placentae are early free from all 

 connexion with the parietes of the ovary, except at the base and 



summit. 



The name proposed for the genus, EopTiylon, refei-s to the 



oriental habitat.
