Notes on Rutaceae — III 
PERcyY WILSON 
Within the past few years, a number of writers on Rutaceae 
have taken up the name Fagara (L. Syst. ed. 10. 897. 1759) 
for the species of Zanthoxylum which have both sepals and petals. 
In his Species Plantarum (270. 1753), Linnaeus mentions only 
two species of Zanthoxylum, Z. Clava-herculis and Z. trifoliatum ; 
the second is an Acanthopanax and belongs to the Araliaceae. 
Z. Clava-hercults is plainly the type of the genus Zanthoxylum. 
In his Genera Plantarum (ed. 5. 130. 1754), the genus Zan- 
thoxylum is credited to Colden and said to be without corolla, and 
it is evident that Linnaeus had in mind Colden’s plant from New 
York, the species afterward described as Z. americanum Mill. 
In his Species Plantarum, however, Linnaeus did not refer to Z. 
americanum, but bases Z. Clava-herculis upon the extended de- 
scription of Zanthoxyl/um in Hortus Cliffortianus and the descrip- 
tion and plate of Catesby. The plant of the Hortus Cliffortianus 
and Catesby possessed a corolla and belongs in what has been 
called Fagara. Fagara then is a mere synonym of Zanthoxylum 
and the latter name should be retained for this genus of Rutaceae.
