NOTES ON JAMAICA PLANTS.

 PlCRODENDRON^. 



In elaborating the SimaruhacecB for the Flora we have con- 

 sidered this genus, which is doubtfully referred to this family by 

 Bentham & Hooker and subsequently by Engler in the Pflanzen- 

 familien. The genus was founded by Planchon in his revision of the 

 family (in Hook. Lond. Journ. Bot. v. 579, 1846), on material collected 

 by Macfadyen, which supplied only vegetative characters and fruit. 



Macfadyen (Jam. i. 225, 1887) had referred the plant to Rhus 

 arhorea DC., and l-*lanchon adopts DeCandoUe's species name under 

 his own new genus, citing the new species as Picrodendron 

 arhorcion. 



Planchon had overlooked the previous descri])tion of the plant by 

 Linnjtus as Juf/lans haccata (Syst. ed. 10, 1272 & Sp. PI. ed. 2, 

 1 11(3) which was based on references to Browne (Hist. Jam. 346) and 

 Sloane (Hist. ii. i. t. 157. f. 1). The original of Sloane's figure is 

 in Herb. Sloane (vol. v. f. 49) and is a s])ecimen bearing immature 

 male inllorescences. Grisebach (Flor. Brit. W. Ind. 177) includes 

 the species under Juglaiidece as Plcrodendron Juglons, Griseb. A 

 second species, based on fruiting matei-ial only, lias more recently 

 been discriminated by Dr. Britton (Bull. New York Bot. Gard. iv. 

 139, 190()) to include plants from Cuba and the Bahamas. 



A specimen bearing male llowers was collected in San Domingo
