cellular and long, pluricellular hairs, the margins and veins above with solitary 

 long setæ. Aërophore large, acute, hairy (as in D. deltoidea). Lower pinnæ more 

 or less reduced, seldom equal to the next pair, sessile or very shortly stalked. 

 Pinnæ alternate, about 8 cm long by IV2 cm broad, the apex acute or acuminate, the 

 base unequal-sided, truncate on the upper, cuneate on the lower side, incised to a 

 narrow wing 1 — 2 mm broad into falcate or oblique, entire or faintly crenate, 

 acute segments, 4 mm broad. Upper basal segment generally a little longer and 

 almost parallel to rachis, the lower (especially in the lower pinnæ) shorter and 

 oblique. Veins 7 — 8-jugate, simple, the basal ones running out to the sinus or a 

 little above it with a hyaline, hairy membrane or (in dried specimens) a distinct 

 keel between them. Sori supramedial, furnished with a large, reddish, persistent 

 indusium, which is glabrous or more often pubescent by short hairs and a few 

 long, deciduous setæ. 



1). L'Herminieri, with which A. trichophorum Fée is absolutely identical, is a 

 fairly constant species, mainly varying in pubescence. A. Capitainei Fée is a form 

 with a glabrous indusium and without long, pluricellular hairs on rachis and veins 

 above, but the rachis and costæ beneath are more densely tomentose by the short 

 hairs; to this form belong all specimens from St. Vincent and Grenada, while the 

 specimens from Guadeloupe are partly this form partly typical. N. Holmei Bak. is 

 the typical form and A. asperulum Fée is intermediate between the two extremes. 

 According to a note in Herb. Berol. by Mettenius Nephrodium clypeolutaiiim Desv. 

 is this species; if so the name of course has priority. — The species seems to be 

 confined to the Tresser Antilles, from which I have seen the following specimens. 

 Mettenius mentions a specimen from Jamaica, leg. Breutel, which I have not 

 seen, and Jenmann does not know the species as Jamaican. The Brazilian specimens 

 referred hereto by Baker in Fl. bras, belong to /). lugubris.
