Sabal Campbelli Newb. 



Dcsc. Leaf very large, eight to ten feet in diameter, witii 

 fifty to seventy folds ; petiole long, sixteen lines or more 

 in width, flat above, without a central keel and unarmed; 

 nerves numerous and fine, about fifty in each fold — six 

 principal nerves on each side of the midrib, with three 

 intermediate nerves between each pair, the middle one 

 being strongest. 



In its general .character this palm bears a strong resem- 

 blance to Sabal major, Ung. Sp. ( Chloris, Prot. S. 42, Taf. 

 14, fig. 2 ; Flor. Tert. Helvet. 1, S. 88, Taf. XXXV. XXXVI. 

 figs. 1, 2,) the size of the leaf, the number of folds and 

 the character of the nervation being nearly the same ; but 

 in our plant the petiole is apparently flat or slightly arched 

 above, without the central keel of S. major. Unfortunately 

 we have as yet obtained no specimen showing the under 

 side of the leaf, and therefore want the important diagnos- 

 tic character of the length of the point of the petiole. 



From Sabal Lamanonis this species may be distin- 

 guished by its greater size, more numerous leaf-folds, 

 finer and more crowded nervation, and by its flat un- 

 keeled petiole. 



Fan-palms are not now found on the Pacific coast above 

 Cape St. Lucas, (Lat. 23° North,) though the average tem- 

 perature would permit them to grow perhaps as far north 

 as San Francisco, (Lat. 38°). In the valley of the Missis- 

 sippi and on the Atlantic coast they extend northward to 

 the parallel of 35°.
