ORDER XCVIII XANTHOXYLACE^E.— Lindl. Nat. Syst. p. 135. 



Trees or shrubs, sometimes climbing, by Lindl. referred to 15 genera. 

 Of these, DC. pr. and Spreng. syst. assign 22 species to S. America, Mex- 

 ico and the W. Indies ; 4 to N. America ; 2 to Senegal ; 1 to Madagas- 

 car ; 6 to Mauritius and Bourbon ; 1 to Abyssinia ; 4 to China ; 2 to Ja- 

 pan ; and 2 to New Holland. S. Africa exhibits 4 species, (Harvey,) and 

 the E. Indies 37. Of the latter 2-3 belong to Brucea ; 22 to Xanthoxy- 

 lum ; 1 to Blackburnia ? (Roxb.) ; 1 to Lacuris ; 3-4 to Toddalia; 4 to Ai- 

 lantus ; 1 to Eurycoma ; and 1 to Ptelea? (Lour.) ; but two are also na- 

 tives of China. With the exception of 1 1 which inhabit Nepal, the Khas- 

 sya and Morung Mountains, the rest arc nearly all natives of the Peninsu- 

 las of India, the Moluccas and Cochin China. The Javanese species, in- 

 cluding Rutese, are stated by Blume to be 14, ( Wight ;) but we are not 

 acquainted with their generic distribution. — To the Mauritius and Bour- 

 bon Xanthoxylacea;, Wall. Cat. adds 2 species of Xanthoxylon. 



" Nearly all the species of this order are aromatic and pungent — Xan- 

 thoxylon Clava Herculis and fraxincum are powerful sudorifics ; they are
