Tepic to Tamaulipas, Veracruz, and Chiapas. West Indies ; Central and 

 South America. 



Tree, 8 to 20 meters high, the branches whorled ; leaves oblong to broadly 

 ovate, 10 to 20 cm. long, acute or acuminate, rounded to acute at base, entire, 

 those on young shoots often 3 or 5-lobate ; umbels few, the pedicels 5 to 10 mm. 

 long; fruit black, about 6 mm. in diameter. "Palo santo " (Tamaulipas); 

 "palo de danta," " mano de danta " (Oaxaca) ; " mano de le6n " (Durango, 

 Sinaloa, El Salvador); " cacho de venado " (Costa Rica); " vibona " (Cuba, 

 Porto Rico) ; "palo cachimba," " bfboua," " ramSn de vaca," " ahorca jibaro " 

 (Cuba); " pana," "palo cachumba," " muneca " (Porto Rico); " vaquero " 

 (Panama). 



The wood is said to be fibrous, rather heavy, yellow, with reddish heartwood. 

 It is little used except for fuel. The leaves are emploj'ed in Tamaulipas as 

 a remedy for fever. 



The writer has seen no authentic material of Marchal's species, but the 

 descriptions do not suggest any important differences. Oilibertia populifolia 

 was made the type of a new subgenus because of its 6-parted (rather than 

 5-parted) flowers, but the flowers of O. arborea appear to be variable in the 

 number of their parts. 



Aralia fruticosa, A. tuxtlensis, and A. longifolia of Sess€ and Mocino* are 

 probably synonyms of this species. 



2. Gilibertia juergenseni (Seem.) Standi. 



Dendropanax jucrgcnseni Seem. Journ. Bot. Brit. & For. 2: 301. 1864. 



Type from Sierra San Pedro Nolasco, Oaxaca. 



Leaves ovate-oblong or oblong, 18 cm. long and 10 cm. wide or smaller, 

 acuminate, entire, attenuate at base ; umbels compound. 



Known to the writer only from the original description ; perhaps only a 

 form of O. arborea.
