FLORIDA PALMS. 

 Among the native palms of peninsular 



Florida are the royal palm (pL 25) which Fig. 



has given its name to Eoyal Palm State 



Park; the saw palmetto so characteristic 



of the pinelands ; the saw cabbage palm, Paurotis wrightii, of coast 



hammocks (pis. 26 and 27) which has sometimes been confused with 



the preceding ; the cabbage palmetto, 

 or cabbage palm (pi. 28) ; the small- 

 deeded, dwarf, blue-stem palmetto, 

 Sabal glahra^i of northern Florida; 

 the large-seeded, dwarf palmetto, 

 Sahal etonia, of southern Florida ; the 

 silver palm of the pine woods near 

 Miami and Homestead, Coccothri- 

 nax argenfea,^ the Florida thatch 

 palm, Thrinax jior'idana; and the 

 brittle thatch, Thrinax microcarpa^ 

 which occurs at the lower extremity 

 of the peninsula. The majority of 

 these species are found also on the 

 Bahamas and other islands of the 

 West Indies; the large-fruited Sahal 

 etonia, however, is endemic. The 

 coconut palm is not a native of 

 Florida, but may be regarded as a 

 naturalized citizen of the State. In 

 the accompanying illustration (pi. 

 28) are shown the seeds of most of 

 these palms which differ so strik- 

 ingly that they will serve to identify 

 the various species. In addition to 

 the seeds themselves the plate in- 

 cludes the dropping of a bird in
