species by its very long, epigæous caudex, about 20 cm long, Vi cm 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 pinnæ. Lamina 40—50 cm long. 5 cm broad, downwards rather 

 suddenly narrowed, light-green when alive, brownish wlien dried, firmly herba- 

 ceous, the rachis slender, very slightly strigose above. Pinnæ very numerous, 

 sessile, the lower 4 — 5 pairs opposite, very remote and verj' small, auriculiform; 

 above them a single pair of larger, auriculiform pinnæ, the next following scarcely 

 shortened; middle pinnæ 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 '/;i of the way to the midrib, the lower one 

 lobed in the centre only. Upper basal lobe the largest, making the pinnæ 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; indusiura 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 

 pinnæ is nearly cut away. The peculiar scaly stem not considered it differs from 

 D. sancta and D. sanctiformis , its nearest lelatives, by the less cut pinnæ and the 

 lamina not being gradually but suddenly narrowed downwards. 



59. D. consanguinea (Fée) C. Chr. Revision nr. 33 fig. 21; Smiths. Misc. Coll. Ô2: 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. 5243 a (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. carihaea (Jenm.) C. Chr. do not belong here. 



61. D. pseudosancta C. Chr. Smiths. Misc. Coll. 53: 378. — Fig. 12 c. 

 Area: Costa Rica, Guatemala. 



Dryopteris négligeas (Jenm.) C. Chr. Index 279. — Nephrodium negligens Jenm. Bull. Bot. Dept. 

 Jam. n. s. 3: 20. ISUd. — Jamaica, is according to a photograph of the type-specimen in Jenman's 

 type-herbarium in New Yorii IJot. Garden, together with a small fragment kindly sent me l)y Miss Slosson 

 a small species allied to D. sancla. but not unlilie small forms of D. oligociirpa; it agrees with the 

 latter in pubescence; some of the pinnæ (3x1 cm) are rather unequal-sided. It may be a valid species.
