be Ph. hyclrophila, but that they agree very well with the figure of Ph. delicatula; 

 about this species Fée says: "aucune espèce connue n'a dans le port une pareille 

 souplesse; elle est délicate dans toutes ses parties", and the specimens seen are 

 remarkable for their delicate leaves and small size; Ph. hyclrophila is, judging 

 from the figure, a larger species with longer and more deeply incised pinnæ; it may 

 however be doubted, if it is really distinct from D. delicatula. The two specimens 

 leg. L'Herminier seen by me are namely not quite identical. The specimen in 

 HC agrees exactly with the figure of D. delicatula; the sori are supramedial and 

 the underside densely glandulose; the specimen in HB differs from the other in 

 its sori being placed near the costa — as described for Ph. hydrophila — and the 

 underside is very sparsely glandulose. Still in size, texture, habit and pubescence 

 the two specimens agree very well. In both specimens the sori are furnished with 

 a persistent, setose indusium. 



Rhizome erect, densely fibrillose. Stems fasciculated, very slender, subglabrous, 

 gray stramineous, rather short. Lamina about 3 cm. long, 5 — 6 cm. broad, delicate, 

 gradually narrowed to both ends, rather densely hairy along rachis, costæ and veins 

 above, the underside finely and shortly hairy both along the costæ and veins and 

 on the parenchyma, and more or less glandulose with red, sessile glands. Lowest 

 pinnæ gradually reduced, largest ones subopposite or alternate, 3—4 cm. long, 

 8—10 mm. broad at the middle, obtuse or shortly acuminate. Segments 6—8 to a 

 side, obtuse with 1—2 obtuse teeth at apex, the upper basal one enlarged. Veins 

 about 3 to a side. 



The species is a near ally of D. sancta, from which it differs by its equal-sided 

 pinnæ and pubescent under surface. Nephrodiiim caribaeum Jenman, Journ. Hot.

Type from San Domingo: Valle nuevo, 2270 m., leg. Eggers n. 2244 (HC). 



Not unlike Ü. delicatula, but less hairy and the segments somewhat incised 

 with 2 — 3 lobes, which in the mature leaf are reflexed, the leaf resembling a Chei- 

 lanthes. Rachis, costæ, costulæ. and margins furnished with some long, while hairs: 

 the leaf otherwise glabrous and without glands; veins 4 to a side, sori medial, 

 exindusiate. Shape of lamina agreeing with type II. 



A rather doubtful species, founded on two leaves. In HB two specimens 

 without indication of locality are found, which very much resemble this species 

 but are furnished with a distinct, reniform, hairy indusium.
