40. A. grandifolium, Swartz. — Rootstock stout, scaly, erect ; stipites 

 caespitose, strong erect, 1-l^ft. 1. dark fibrillose at the base; rachis 

 similar ; fronds pinnate, erect, 1 -2 J ft. 1. f - 1 ft. w. truncate and not re- 

 duced at the base, dark green, paler beneath and brownish, firm pellucid, 

 naked; pinnae nearly horizontal, opposite or alternate, 4-6 in. 1. lj-lf 

 in. w., distant or sub -distant, less often approximate, sessile or the lower 

 petiolate, acuminate, the base equal-sided, rounded, or the upper sub- 

 cordate and gradually becoming fully adnate passing into the lobate- 

 entire acuminate apex : margins entire, sinuate or sinuate-lobate, some- 

 times serrate towards the point ; veins at a wide angle, 2-4 times forked, 

 in fascicles of 4-6 each ; sori copious, occupying all but the central vein- 

 lets, the inferior outer ones double and in. 1 ; involucres broad, dark 

 bro^n at maturity. — Diplnzium, Sw. Heinionitis, Sm. 



Very common in moist woods on the banks of rivers among ihe lower 

 hills, and ascending to 1,500 ft. alt. A fine and very beautiful plant, 

 the underside picturesque with the copious sori and dark, brown, glossy 

 involucres on the background of pale green surface. 



41. A celt id if ol in Mett - Eootstock stout, erect, reaching \\ ft. 

 high, paleaceous at the summit, stipites coespitose, 1-1 \ ft. 1., scaly 

 beneath, specially at the base, light green, the rachis simdar, fronds 

 pinnate, \\-'^\ ft. 1., f— 1J ft. w., light green, pellucid and rather thin, 

 slightly fribrillose on the ribs beneath, upper side naked, reduced little 

 or much at the base ; pinnnae numerous, mostly horizontal, close or 

 nearly so, 6-10 in. L, 1-2 in. br , acuminate or acute, quite sessile and 

 subcordate, often auricled on the lower base overlapping the rachis, 

 upper ones passing gradually through pinnatifid to lobed into the ser- 

 rulate acuminate apex of the fronds; margins repand or sinuate lobate ; 

 veins close, pinnato-fasciculate the branches of each group running sub- 

 parallel towards the margin ; sori thin or very copions on all the lower, 

 branches, reaching half to three-forths from midrib to margin, all or 

 nearly all double ; involucres pale, narrow,-- Diplazium, Kze. A. cen- 

 tripetakf Baker. 



Common in moist forests from 2o00-6000 ft alt. Usually the sori 

 are only on the inferior veinlets, and reach only half-way from the mid- 

 rib to the margin, but in the largest states the shorter outer branches 

 are also fertile, and, in consequence of the proximity of the nearly pa- 

 rallel veins, the surface is covered almost 10 the edge. The scales be- 

 come fibrillose as they ascend from the base of the stipites. It was first 

 gathered by James Harlow, who took plants home, two hundred years 

 ago. The widely spread A. syfoaticum, Presl. found lately in Cuba by 

 Eggers has somewhat narrower firmly coriaceous, bright glossy pinnae, 

 auricled on both sides at the base, the lower distant and much reduced. 

 A. Godmani, Baker, recently discovered in St Vincent and Grenada 

 resembles the larger states, but has fronds and pinnae twice as large, 

 with more open venation, the veinlets, more especially the outer ones, 

 more or less anastomosing.
