Nephrodium rigidulum). His plant is evidently identical with the following variety, 

 which does not exactly agree with the specimens from Cuba: 



var. jamaicensis n. var. 



Jamaica: Mt. Diabolo, 2000', L. M. Underwood n. 1826 (HC). 



A typo difFert: minus coriacea minus pubescenti vel rachi costisque superne 

 exceptis subglabra, subtus dense glandulosa, glandulis aureis. Venis omnibus 

 indivisis.

 (sic!) Bak. Syn. Fil. 496. 1874. 



Type from Venezuela: Sierra Nevada, leg. Funck n. 502 (HB). 



Columbia: Lehmann n. 6956 (HB). 



An andine species, well-marked by its rather stiff, fragile texture, dark-green 

 colour and especially by its scales. 



Rhizome erect with many densely fasciculated leaves at its apex; the bases of 

 the stipes are nearly quite hidden by a dense mass of long, thin, red-brown scales, 

 Stem very short. Lamina c. 5 dem. long by 5 cm. broad at the middle, downwards 

 very gradually narrowed with numerous reduced pinnæ, almost as in D. opposita 

 (type II). Rachis rather strong, hairy and like costæ beneath furnished with 

 black-brown, acuminate scales. The pinnæ of the lower half of the lamina reflexed, 

 the lowermost very small with distances of about 1 cm. between them. Upper 

 surface of the leaf pubescent, under one glabrous. 4 — 5 pair of veins; sori supra- 

 medial with a distinct, setose indusium. 



HiERONYMus distinguishes 3 varieties from Columbia and Peru (Hedwigia 46: 

 335. 1907).

 Jamaica n. s. 3: 68. 1896. 



Type from Jamaica. A specimen in HB. leg. Jenman is probably an authen- 

 tic one; with it exactly agrees another specimen from the type locality: Blue Moun- 

 tain Peak, 6—7000', leg. L. M. Underwood n. 1435 (HC). 



A very distinct species, resembling D. scalpiuroides in texture and in its pro- 

 minent veins, but widely different in having a creeping rhizome, which is clothed 

 at its top by a dense cluster of brown scales, in its setose sporangia, and 

 especially in its leaf being only very slightly reduced towards the base or some- 

 times totally wanting reduced pinnæ. The lower pair of the larger pinnæ are 

 somewhat shortened and reflexed and below them sometimes one pair of very 

 small auriculiform pinnæ can be found. The lamina is glabrous with exception 

 of the sparsely and shortly pubescent rachis and costæ above; the underside is
