at the middle incised a little more than halfway to the midrib with entire, ob- 
tuse lobes; the veins once forked and the sori uniserial. This is the common form 
in Jamaica. In San Domingo the form described as Pol. domingense Spr. is apparently 
very common. Its leaves are longer (30cm or more) but scarcely broader than in 
the Jamaican form and on longer stems but otherwise not materially different. In 
Porto Rico and Guadeloupe the most common forms are the large var. portoricensis 
Kuhn (Porto Rico) and the true P. guadalupense Wikstr. (syn. Goniopteris affinis Fée) 
(Guadeloupe) The leaves.of these forms are up to 50 cm long on long stems, often 
more than 10cm broad at the middle, incised almost to the midrib in broadly linear 
segments, which are 4—5 cm long, 1 cm broad and often again deeply lobed. Veins 
pinnate in the lobes and sori in several rows or even in a distinct row on each 
side of the secondary veins. The middle segments are often considerably and une- 
qually lengthened.

The plant described as Goniopteris gracilis Moore et Houlst. Gard. Chron. 1856: 
301, fig, of which I have seen authentical specimens (B), can, I think, safely be 
regarded as a form of D. guadalupensis, while several other forms, cultivated under 
the name G. gracilis, are to refer to D. reptans. The true G. gracilis is a form with 
many free pinne and with a proliferous bud in the upper part of the midrib. 
212. Dryopteris Peripae (Sod.) C. Chr. Index 284. 1905. — Fig. 28 d. 
Syn. Nephrodium Peripae Sodiro, Rec. 52. 1883; Cr. vasc. quit. 265. 1893. 
Type from Ecuador, secus flum. Peripa, leg. Soprro (Kew!) 
A distinct species, perhaps nearest related to D. Levyi and D. guadalupensis; it 
resembles also D. hastata in its long pinnatifid apex, which is not much shorter 
than the lower pinnate portion of the lamina, but otherwise it is very different. — 
The short creeping or decumbent rhizome bears some few stellato-pubescent scales.
