I have redescribed this species after the specimens from Martinique, leg. Père 

 Duss, which exactly agree with Fee's figure and which I take for the typical form. 

 Eggers' specimens are similar but smaller: Leaf 2—4 dem. long, 6 — 9 cm. broad, 

 largest pinnæ 5 cm. long, 1 cm. broad, the segments with only 3 — 5 pair of veins, 

 otherwise it is typical. — It is one of the most well-marked species of the whole 

 group, very characteristic by its unequal-sided, caudate-acuminate pinnæ, the basal 

 segments of which imbricate the rachis as in D. limbata. It resembles D. sancta 

 in the shape of the pinnæ with the shorter lower segments, and it has, probably, 

 often been confounded with that species, from which it differs by its opposite, 

 caudate, not so deeply incised pinnæ, by its prominent veins, more glandulose 

 underside and persistent indusium.

Type specimen from Cuba: Monte Verde, leg. Wright n. 820 (HH. HS!). 

 Also leg. Palmer & Riley n. 195, in mountains near El Guama, Province of Pinar 

 del Rio, 3/:i 1900 (HH). 



In habit between D. opposita and D. panamensis, in its coriaceous texture like 

 D. firma, the typical form eglandulose on the under surface. Rhizome erect, the 

 leaves spreading, shuttle-cock form, very short-stalked, and downwards gradually 

 narrowed through many hastate-tripartite auricles (tyj)e II) almost as in D. opposita, 

 upwards rather suddenly narrowed to the apex, broadest a little above the middle, 

 hairy on rachis and the upperside, sparsely pubescent on costæ and veins beneath. 

 Largest pinnæ about 6 cm. long by 1 cm broad, broadest at the middle, sometimes 

 (as in the type specimen) unequal-sided, the middle lower segments being some- 

 what enlarged. Segments closely placed, rather oblique, the basal one the largest 

 and the posterior basal one often with an auricle, which covers the upperside of 

 the rachis. Veins 5 — 6, prominent on the upperside, the lowest or the two lowest 

 posterior ones often furcate. Sori near the edge. Indusium reniform, setose. 



The species is recorded from Jamaica by Jenman (Bull. Dept. Jam. 3 : 22. 1896,
