species by its very long, epigeeous caudex, about 20 cm long, '/: em thick, clothed 
throughout with squarrose, glossy, castaneous, lanceolate-acuminate, narrow, pubes- 
cent scales. Stipe glossy, glabrous, about 5—6 cm long to the lowermost pair of 
auriculiform pinne. Lamina 40—50 cm long. 5 cm broad, downwards rather 
suddenly narrowed, light-green when alive, brownish when dried, firmly herba- 
ceous, the rachis slender, very slightly strigose above. Pinnze very numerous, 
sessile, the lower 4—5 pairs opposite, very remote and very small, auriculiform ; 
above them a single pair of larger, auriculiform pinne, the next following scarcely 
shortened; middle pinnz alternate, 3 cm long, 7--8 mm broad, acute, auricled at 
the upper base, cuneate on the lower side, very finely pubescent on the upper sur- 
face, glabrous and eglandulose beneath, entire in the outer third, the upper margin 
lobed in the lower two-thirds about '/s of the way to the midrib, the lower one 
lobed in the centre only. Upper basal lobe the largest, making the pinnz auricled, 
central lobes about as broad as long, obtuse. Veins pinnate in the lobes with 
1—3 pairs of tertiary simple veins. Sori medial, small; indusium subpersistent, 
brown, glabrous. Sporangia glabrous. 
In general habit this species resembles not a little a species of Asplenium, 
f. inst. A. unilaterale Lam., because the lower half of the basiscop side of the 
pinne is nearly cut away. The peculiar scaly stem not considered it differs from 
D. sancta and D. sanctiformis, its nearest relatives, by the less cut pinnz and the 
lamina not being gradually but suddenly narrowed downwards. 
59. D. consanguinea (Fée) C. Chr. Revision nr. 33 fig. 21; Smiths. Misc. Coll. 52: 380. 
Area: Trinidad, Grenada, Martinique, Dominica, Guadeloupe. Jamaica (var. 
aequalis). Panama. 
This species may be a small form of D. limbata. I refer to it a peculiar 
variety from Panama, Chiriqui, 1000—1300 m; Maxon nr. 5243a (W). It is in 
habit perfectly typical, but the underside is eglandulose and the sori are very 
small, consisting of some few (3—4) sporangia, without trace of indusia and placed 
very close to the margin nearly apical on the veins. 
60. D. delicatula (Fée) C. Chr. Revision nr. 30. 
Area: Guadeloupe. — The lamina is about 30 cm long, not 3 cm as errone- 
ously stated in “Revision” 295. 
D. hydrophila (Fée) C. Chr. and D. caribaea (Jenm.) C. Chr. do not belong here. 
61. D. pseudosancta C. Chr. Smiths. Misc. Coll. 52: 378. — Fig. 12c. 
Area: Costa Rica, Guatemala. 
Dryopteris negligens (Jenm.) C. Chr. Index 279. — Nephrodium negligens Jenm. Bull. Bot. Dept. 
Jam. n.s. 3: 20. 1896. — Jamaica, is according to a photograph of the type-specimen in JENMAN's 
type-herbarium in New York Bot. Garden, together with a small fragment kindly sent me by Miss SLosson 
a small species allied to D. sancía, but not unlike small forms of D. oligocarpa; it agrees with the 
latter in pubescence; some of the pinnze (3 >< 1 cm) are rather unequal-sided. It may be a valid species.
