the apex caudate, the base of lower pinnæ reduced; lower pinnæ not shortened. 

 Rachis slender, finely downy by minute hairs, soon glabrous. Pinnæ above slightly 

 strigose on the deeply channelled costæ, elsewhere glabrous, the generally flat 

 costæ and costulæ beneath microscopically puberulous, by simple hairs, the leaf- 

 tissue glabrous. Scale-like fibrils of the costæ beneath few and scattered. Pinnæ 

 incised scarcely to the middle into broad, falcate, entire segments. Veins simple, 

 12 — 16-jugate, the lower 3—4 forming aréoles between the costule and the mem- 

 brane; sometimes those of the basal pair are truly anastomosing fnervatio Goniopte- 

 ridisj. Sori small, medial or somewhat inframedial. I have failed to find an 

 indusium, which Jenman describes as small and ciliate. Sporangia glabrous. 



Desvaux identified Plumier's plate 21 with this species and was no doubt 

 right; Ph. Plumieri was based on the same plate. D. glandiilosa is in its typical 

 form a common fern in the Lesser Antilles. Jenman records it also from Jamaica 

 and Guiana. Nephr. dejectiim Jenm. is according to a photograph of Jenman's ori- 

 ginal specimen kindly sent me by Miss Slosson together with a small fragment of 

 the same not to distinguish from the type. Jenman describes the rhizome as erect 

 and the sori as indusiale. — 1 have seen the following specimens:

Nephrodium Grayii, Jenman, W. Ind. and Guiana Ferns 235 1908 from St. 

 Lucia, Gray nr. 17, is, judging from the description, this species. 



In Central America and South-American Andes a plant occurs, which perhaps 

 is specifically different from Ü. glandiilosa but which I now regard as a variety of 

 this species. It is 



var. brachyodus (Kunze).

In pubescence, size, cutting and venation scarcely different from D. glandiilosa 

 type; it differs mainly by its thinner texture, darker upperside, alternate pinnæ 

 and its less falcate lobes. The costæ and coslules beneath are more decidedly 

 fibrinöse by red-brown fibrils, which often cover the aërophore. Mettenius found 

 the difference between this variety and the type in the goniopteroid venation of
