Ord. EUTACE^l (DIOSME.E, R.Br.). 



It is abundantly evident, from the comparison of Euodia, Melicope, 

 Acronychia, &c. with Zanthoxylum on the one hand, and with the 

 true Diosmece on the other, that the characters by which Endlicher 

 distinguished his Zanihoxylece from his Diosmece are of no value what- 

 ever; and that the view of the family long ago suggested by Brown 

 should be adopted ; retaining, however, the name of Butacece. Al- 

 though the Hue and its nearest allies are "not calculated to give a 

 clear idea of the order, from the usual structure and habit of which 

 they deviate in some important points ;" yet the name in use for the 

 group cannot now be readily discarded, any more than in the analo- 

 gous case of the Eupliorbiacece.
