Part 3, 1911] RUTACEAE 199 



Little known or doubtful species 



Fagara domingensis Krug & Urban ; Urban, Bot. Jahrb. 21 : 5S6. 1S96. 



Fagara falcifolia Engler, Bot. Jahrb. 21 : Beibl. 54 : 24. 1S96. Described from a 

 young sterile specimen collected by Liebmann at Mirador, Vera Cruz. The type sheet in 

 the herbarium of the Museum Botanicum Hauniense is very similar to a young sterile 

 shoot of a Zanthoxylum from Jamaica. It is probable that the species belongs with Z. 

 Elephantiasis Macfad. or Z. Nelsoni Rose. 



Fagara pilosissima Engler, Bot. Jahrb. 21 : Beibl. 54: 26. 1896. Known to me only 

 from fragments of foliage, and follicles which bear no sepals. Possibly related to Z. Clava- 

 Herculis L. 



Tenorea corymbosa Raf. Specchio 1 : 193. 1S14. Zanthoxylum corymbosum (Raf.) 

 DC. Prodr. 1 : 726. 1S24. 



Zanthoxylum granulation (Krug & Urban) P. Wilson, Bull. Torrey Club 37: 86. 

 1910. Fagara granulata Krug & Urban ; Urban, Bot. Jahrb. 21 : 594. 1896. Known only 

 from sterile material collected in Santo Domingo and Cuba. Probably not of this genus. 



Zanthoxylum horridum Moc. & Sesse\ Fl. Mex. 231. 1894. Not Z. horridum 

 (Thunb.) DC. 



Zanthoxylum rigidum H. &B.; Willd. Sp. PI. 4: 756. 1806. Recorded from Panama 

 by Hemsley, Biol. Cent. Am. Bot. 1 : 169. 1897.

 21 : 594. 1896. 



Zanthoxylum Sumac Macfad. Fl. Jam. 1 : 195. 1837.= Brunellia Sumac Planch., which
