208 RUTACEAE. 



as long as the petals; pistillate flowers -with a glandular-punctate ovary and 

 short styles; follicles obovoid, 5-9 mm. long; seeds black, shining, 4-5 mm. long- 



White-lands and low coppices, throughout the archipelago from Abaco and Great 

 Bahama to (Irand Turk and Ambergris Cay. Inagna and the Anguilla Isles: Ber- 

 muda: Florida: Cuban Cays; Jamaica. Santo Domingo to St. Lucia. Referred by 

 Dolley to Zanthoxylum fraxineum Willd. Yellow-wood. Satin-wood. 



The occurrence of Zanthoxylum Clava-Herculis L. in the Bahamas as 

 recorded by Dolley is extremely doubtful; both Z. coriaceum and Caesalpinin 

 bahamcnsis are locally known through the archipelago as "Hercules' Club."
