in woods or shady places ; abundant in the eastern and central pa- 

 rishes. The sori are chiefly on free included appendages, the other 

 areolae being devoid of veinlets. The papillose surface is a striking 

 feature in the growing plants. The upper pinnae are adnate to the ra- 

 chis and the higher ones decurrent. All the segments but the ulti- 

 mate lobes are sharp. 



56. N. macrophyllum, Swartz. — Rootstock stout, erect ; stipites caes- 

 pitose, erect, strong, 1-2 ft. 1. brown or purplish, with a few deciduous 

 scales chiefly at the base ; fronds erect, oblong, pinnate, 1-2 \ ft. 1. 

 from less than 1-2 ft. w. ; chartaceous, the surface repand usually 

 naked, light or dark green, paler beneath ; pinnae in 2-6 or more usu- 

 ally large, distant pairs, horizontal or erecto-spreading, acuminate, 

 8-12 in. 1. 1-3 in w. ; the lowest pair not shortened, and shortly stipi- 

 tate or sessile, forked, inferior division the shorter, the midrib below 

 the fork devoid of membrane on the inferior side at the base ; upper 

 pinnae more or less adnate at the base, specially on the lower side of 

 the midrib, those below these rounded and free, not olten lobed ; ter- 

 minal division large, decurrent tripartite generally, the central seg- 

 ment largest, and often deeply lobed, margins repand or sinuate lobate, 

 main veins costaeform, curving and evanescent at the margins, \-\ in. 

 apart, the areolation fine, with free included veinlets ; sori biserial be- 

 tween the primary veins, contiguous to and parallel therewith, involu- 

 cres reniform-orbicular, persistent. — PI. Fil. t. 145. Aspidium, Sw. 



a. var pilosum — Both surfaces freely pubescent, including both ra- 

 chis and stipe. — Cardiochlcena pilosa, Fee. 



b. var. vivipartm- — Pinnae more numerous, mostly viviparous near 

 the base on the upper and superior side ; the lower ones lobed on both 

 sides, pinnatifid or fully pinnate at the base. 



Common in woods and forests and half -open places at low elevations. 

 Variable in size, and in the number, lobing and size of the pinnae. 

 The forked basal pair have often a small lobe or lobes on one or both 

 sides of the main divisions, and this incipient lobing sometimes ex- 

 tends to the two or three pairs next above them. a. was gathered by 

 Miss Taylor in Jamaica. Her specimen, which I have, is densely pi- 

 lose, but otherwise does not differ from the type. This form is found 

 also in Brazil, b. is very abundant along some of the Guiana Rivers. 

 The proliferous habit which it has developed in its aquatic home is a 

 striking feature, the plants usually supporting numerous young, more 

 or less developed, plants on their leaves. The pinnae too are more 

 numerous, and deeply lobed on both sides.
