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 4i by the lamina being fully pinnate below with several 

 pairs of free pinnæ, which diminish gradually downwards. Bent 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 aréoles 

 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 dig. 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 slellato-pilose indusium. According to 

 Jenman the barren fronds are viviparous near the apex. I have seen some fruiid?. 

 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 varieties, although there is a great difference in habit be- 

 tween the small form figured by Plukenet lab. 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. littorale Jenm. In the former the leaves are numerous on 

 very short stems, the fertile ones scarcely more than 20 cm long, 2 — 2';3cm broad,
