 upper part not cut down to the rachis, with oblong, entire lobes, 

 iin. to iin. long, |in. broad ; lower pinnae 1ft to IJft long, 6in. to 

 9in. broad, with numerous lanceolate pinnules on each side, which 

 are cut down to a broadly-winged rachis into lobes about iin. long 

 and iin. broad ; rachis and both surfaces hairy, tori lateral in 

 the ultimate lobes, but not reaching the apex. West Indies. 

 (H. S. F. 132B.) P. Gheisbreghtii is aTess hairy. Mexican variety. 



P. leptophylla (slender-fronded).* *ti. 6in. to 9in. long, erect, firm, 

 straw-coloured, frondt 9in. to 12in. each way, deltoid ; a few of 

 the upper pinnae simple, the largest of these under Iin. long, in. 

 broad, decnrrent at base, strongly spinulose-serrate when barren ; 

 central pinnae lanceolate, caudate, pinnatifid, with numerous 

 similar pinnules ; lowest pinna? deltoid, with pinnules often 

 2in. long, and again pinnatifid. tori not reaching the tips of the 

 segments. Brazil, 1824. See Fig. 310. (H. G. F. 21) SYN.

 numerous linear lobes, the lowest of which are 6in. to Sin. long 

 and iin. broad, with about Iin. between them at the base, the 

 point gradually narrowed and Tery faintly toothed when barren ; 

 Literal pinnae few, often only a single pair, like the terminal one, 

 but smaller, tori not reaching the tips of the segments. Brazil

P. *r<ima. -(Milne's), sti. strong, erect, yellowish-brown 

 frondt 2ft to 3ft. long, with numerous pinnae on each side, cut 



down throughout nearly to the rachis into linear-oblong, falcate 

 lobes, |in. to iin. long ; lowest pinnae 6in. to Sin. long, Iin. to 

 IJin. broad, with a single similar, bat smaller, pinnule at the 



base on the lower side, tori falling short of the sub-entire tips.
