Goniopteris strigosa Fée, 11 mém. 59 tab. 15 fig. 1. 1866. 
Nephrodium strigosum Jenm. Bull. Dept. Jam. n.s.3: 141. 1896. 
Type from San Domingo, PruwiEn Fil. tab. 91. 
To this species I refer all specimens without free pinne but with the lamina 
narrowed below gradually into an entire or faintly toothed wing, '/2 em broad. By 
this character it is always different from D. guadalupensis (Wikstr.) with which 
METTENIUS united il, and I have not found intermediate forms between the 
two species. In Ark. fór Bot. 9'! I have given my reasons for my considering Pol. 
incisum Sw. and Aspidium stenopteris identical with the true D. scolopendrioides (L.), 
which was based on PruwrER lab.91, but later by LiNNAEUS confounded with my 
D. guadalupensis (Wikstr.). The confusion in the nomenclature of these two species 
was due to Swartz, who rightly distinguished the two species but unfortunately 
used the specific name scolopendrioides for the latter species and renamed the former 
Pol. incisum, and most authors have followed Swartz in his nomenclature. D. sco- 
lopendrioides varies mainly in size, especially in breadth, but it is otherwise a rather 
uniform species, which shows several good distinctive characters. The leaves are 
densely fasciculate on an erect or shortly oblique rhizome, sometimes 20—30 to a 
rhizome. The short stem (1—4 em) is when young clothed with brown or blackish, 
stellato-pilose scales. Some of the leaves, which are normally sterile, are short and 
spreading, others up to 4dem long, erect and fertile and sometimes ending in a 
retuse viviparous apex with a rosette of small leaves. The lamina, which tapers 
gradually from the middle to both ends, is generally linear, ca. 3cm broad at the 
middle, and varies from being deeply and broadly serrate to pinnatifid ‘/s or 1/2 
of the way to the midrib with triangular, acute lobes, which are often very une- 
qual in size, some of them being lengthened, 3—4cm long. Texture more or less 
coriaceous, often very rigid. Stem, midrib and veins beneath generally densely 
stellato-pubescent by short multibranched hairs; upperside and leaf-tissue beneath 
as a rule glabrous, but the under-surface distinctly verrucose. Veins raised beneath, 
simple or rarely forked, the basal pair anastomosing. Sori supramedial in a single 
row — seldom in two rows — furnished with a small stellato-pilose indusium. 
Sporangia glabrous. 
The common Cuban form (A. stenopleris Kze.) differs from the type by a longer 
stem and much lengthened middle segments with furcate veins, which in the lar- 
gest forms are sometimes found anastomosing, and by its very long decurrent base 
of the lamina, but I can not consider that form different from the type even as a 
variely. Pol.praelongum Poir. is essentially the same, but its veins are more bran- 
ched and the sori in the lengthened segments often biserial.
