1. Roystonea regia, Cook. Royal Palm. 

 (Oreodoxa regia, Silca N. Am. x. 31.) 



Leaves 10-12 long, closely pinnate, the pinnae 2^-3 long, !' wide near the 

 base of the leaf, and gradually decreasing in size toward its apex, deep green with 

 slender conspicuous veins, and covered below with minute pale glandular dots, their 

 petioles almost terete, concave near the base, with thin edges separating irregularly 



into pale fibres, and enlarged into bright green cylindrical clasping bases 8 or 9 

 long and more or less covered with dark chaffy scales. Flowers: spadix about 2 long, 

 with a nearly terete peduncle and slightly ridged primary and secondary branches 

 compressed above, abruptly enlarged at the base, and simple slender flexuose long- 

 pointed flower-bearing branchlets 3' -6' long, pendant and closely pressed against 

 the secondary branches. Flowers opening in Florida in January and February, the 

 staminate nearly \' long and rather more than twice as long as the pistillate. Fruit 

 oblong-obovate, full and rounded at the apex, narrowed at the base, violet-blue, 

 about ' long, with a thin outer coat and a light red-brown inner coat, loose and 

 fibrous on the outer surface, and closely investing the thin light brown seed. 



A tree, 80-100 high, with a trunk rising from an abruptly enlarged base, grad-

 light gray rind tinged with orange color, marked with dark blotches and irregularly 

 broken into minute plates, the green upper portion 8-10 long, and a broad head
