Type from Guadeloupe, leg. Fonssrnów (S!) 
A variable species, especially in size and degree of cutting, but fairly constant 
in several characters, by which it can be distinguished from D. scolopendrioides. It 
resembles that species in its mode of growth, scales and stellate pubescence, but it 
differs by 1) thinner texture and generally not verrucose under-surface, 2) venation, 
3) inframedial sori and 4) by the lamina being fully pinnate below with several 
pairs of free pinnz, which diminish gradually downwards. Heal intermediates be- 
tween the two species I have not found. The veins are, as a rule, forked or, in 
the larger form, pinnate in the lobes, always forming a row of very narrow areoles 
on both sides of the midrib of the lamina and generally also anastomosing in the 
segments with a single row of meshes along the main-veins or costa (fig. 28 b). The 
sori are always inframedial, in the smaller forms in a single row, in the larger ones 
bi- or pluri-serial, furnished with a small stellato-pilose indusium. According to 
JENMAN the barren fronds are viviparous near the apex. I have seen some fronds 
from Porto Rico, which are fertile and viviparous at the apex. 
To this species I refer a long row af forms, which JENMAN referred to three 
varieties; these are however connected with so numerous intermediates, that I dare 
not consider them good varielies, although there is a great difference in habit be- 
tween the small form figured by PrukENET tab. 290 fig. 1 (— Pol. scolopendrioides 
L. ed. II and Sw.) and the large plants described as Goniopteris affinis Fée, var. por- 
toricensis Kuhn and var. litlorale Jenm. In the former the leaves are numerous on 
very short stems, the fertile ones scarcely more than 20 cm long, 2—2'/»em broad,
