 at base, distinct, 1-1| lin. apart in centre of frond ; sori unequal, the longer 

 reaching nearly to both midrib and edge. Kuhn, Fil. Afr. p. 114. 



Hab. Prince's Island, West Africa, Barter, Mann. Very near concolor. 



1C*. A. Pearcei, Baker ; st. 2-3 in. L, slender, greenish, naked ; basal scales 

 minute, dense, lanceolate, dark -brown ; fr. simple (cristate at the apex in the 

 specimens gathered), lanceolate, 5-6 in. 1., 1 in. br., entire, narrowed suddenly 

 at the base ; texture membranous ; surfaces dull-green, naked ; veins distinct,

Hab. Andes, Pozuzo, 6-7,000 ft., Pearce. 



37. A. adutierinum, Milde. Fil. Eur. p. 16, Silesia and Bohemia, recedes from 

 type towards viride, by its more flaccid texture and green colour of upper part 

 of wingless rachis ; A. Newmanni, C. Bolle, Milde. Fil. Eur. p. 69, Cape Verdes, 

 is said to differ by its conspicuously ribbed rachis, pinnse sessile from a broad 

 base, with a few linear and filmllose scales beneath, basal scales without a 

 spurious nerve ; A. denudatum, Mett. Kuhn, Linn. 36. p. 93, Peru, has few short 

 subcostular sori ; A. Wagneri, Mett. Kuhn, Lin. 36. p. 96, Andes of Quito, 

 Spruce, 5630, is a large proliferous form like castaneum ; var. deflexum, Baker, 

 Guatemala, Salvin and Godman, has much-deflexed subacute mciso-pinnatifid 

 pinna) with crowded oblique oblong 6-12-jugate sori. 



42*. A. nigricans, Eaton ; st. 4-5 in., tufted, naked, castaneous, winged 

 upwards ; fr. lanceolate, simply pinnate, 8-12 in. L, 18-21 lin. br. ; rachis nearly 

 black, naked, distinctly winged ; pinnaz 15-20-jugate, sessile, rhomboid, central 

 f-| in. br., base on upper side parallel with rachis, on lower cut away at right 

 angles with rachis, apex subdeltoid, blunt, rather ascending, inciso-crenate like 

 horizontal upper border, which in lower pinnae is auricled at base ; lowest pinna; 

 distant, shorter, broader, cuneate-truncate at base on lower side ; texture 

 chartaceous ; surfaces naked ; veins distinct, pinnate-flabellate ; sori 1-4, large, 

 oblong, mostly in lower outer third of pinnae. 



Hab. Chiapas, Mexico, Gheisbreght, 377. 



50*. A. subnudum, Baker; st. and rachis grey-black, with a few minute 

 subtilate grey scales ; fr. oblong-deltoid, caudate, 1 ft. 1., | ft. br., simply 

 pinnate ; pinnce 4-5-jugate, erecto-patent, 5-6 in. 1., f-f in. br., ligulate-acu- 

 minate, subequally cuneate at base, nearly sessile, inciso-crenate, more sharply 

 so towards the tip, lowest not reduced ; texture subcoriaceous ; under surface and 

 edge with a few obscure scattered grey scales ; veins distant, distinct, arcuate- 

 ascending, forked ; sori in upper half of pinnae, 3-4 lin. 1., nearer edge than 

 midrib. 



Hab. New Caledonia, Richards, in Herb. Madeay. 



51*. A. Carruthersii, Baker ; st. tufted, grey-stramineous, bordered upwards 

 like rachis with a few adpressed minute brown scales ; fr. oblong-lanceolate, 

 6-15 in. L; pinna 4-5-jugate, ascending, distant, distinctly stalked, ligulate- 

 lanceolate, acuminate, 4-5 in. L, |-1|- in. br., obscurely or distinctly crenate, 

 base unequally or subequally cuneate, lowest not reduced, the edge thickened, 

 pale ; texture coriaceous ; surfaces naked, pale grey-green ; veins fine, close, 

 erecto-patent, immersed ; sori 3-4 lin. L, regular, subcostular, falling far short of 

 the edge ; inv. firm, broad. A. salignum, Carr. Ft. Vit. p. 354. non Blume. 



Hab. Viti, Seemann, 817 ; Darnel, 142-3. Hooker's plate of salignum is drawn from 

 one of Blume's own specimens ; that of Mettenius (Fil. Lips. t. 7) looks like this Vitian 

 plant.
