202 JAMAICA FERNS. 



erect, often a span or more liigli ; sti^Dites caespitose, strong, 

 numerous, 9 to 16 inches long, clothed at the base (and a few scat- 

 tered upwards) with deciduous, dark, dull brown scales ; fronds 

 pinnate, 18 inches to 2^ feet long, 9 to 12 inches wide, apex 

 acuminate,, pinnatifid and ^Dassing through mere lobes into the 

 serrate attenuated point ; pinnae numerous, but distant, spreading 

 horizontally, 4 to 6 inches long (variable in width) f to 1 mch 

 wdde, the lowest one to two pah's little or hardly reduced, and some- 

 times narrowed at the base, upper ones sessile, truncate ; point 

 finely acuminate, serrato-entire, within cut a third or rather more 

 to the costaB into broadish, rounded, or subappressed, thin carti- 

 laginous-edged, crenato-entire lobes, which are 2 to 3 lines wide ; 

 texture thinly papyraceous ; pellucid ; colour dark green above and 

 glossy, j)ale beneath from minute microscopic greyish scales ; 

 rachis puberulous ; veins pellucid, simple, 4 to 8 to a side, lowest 

 j)air uniting and sending a vein to the sinus, where the next pair 

 meet ; sori medial or nearer the midrib, reaching to the lowest 

 vein ; involucre minute, soon obliterated. No. 42, Herb. Kew, 

 1878. Hitherto probably confounded with Pohjpodiwn tetragonum, 

 Sw., from which Mr. Baker hesitates to separate it. With a full 

 knowledge of the two j)lants, there can be no question as to their 

 being most thoroughly distinct.

 Fee's plant in habit and pinnae, but with a dark purple involucre 

 clearly observable on the undeveloped fronds.
