Hab. Brazil, woods in the Mandiocca Mountains (both varieties), Raddi ; Rio, 

 Burchell, n. 2031, Gardner, n. 36. — Var. j8. Rocks, in shady woods, in the Or- 

 gan Mountains, Gardner, n. 150 and 151. — This would seem to be rather a scarce 

 species, judging from the comparatively few specimens we have received : and all 

 are from the vicinity of Rio or from the Organ Mountains. The fronds are from 

 4 inches to a foot long ; the lobes iit the base are liable to considerable variation, 

 sometimes deflexed and sagittate, sometimes patent and hastate. In one of our 

 specimens the patent lobes at the base have a slight curvature upwards, are 

 nearly as long as the main portion of the fronds, and are bipartite, the additional 

 lobe (half its size) is strictly deflected so as to be parallel with the stipes. 



79. Pt. (Litobrochia) pedata, L. ; caudex short thick erect 

 or declined copiously rooting, fronds fasciculate when mature 

 coriaceous opaque cordate tripartito-pedate, lateral primary 

 divisions bipartite on the inferior side or on both sides pin- 

 natifid, terminal one pinnatifid generally cuneate and nar- 

 rowed at the base, the segments with entire lobes or again 

 pinnatifid, ultimate ones oblong with more or less acute 

 sinuses, the margin of the sterile plant crenulated, sori con- 

 tinuous, involucres narrow entire, veins everywhere anasto- 

 mosing so as to form a network of oblong hexagonal areoles, 

 stipes terete ebony-black hispid at the base. — Limi. Sp. PL
