The family of Simarubeee, as reconstituted by Bentham and Hooker fil. and Planohon, only differs 

 from Eidacete, Diosmea, Zanthoxylers, and Hesperideai in its eglandular leaves, often bitter bark, and 

 filaments usually furnished with a scale ; characters -which, although not of a high intrinsic value,
