Type from Brazil, Herb. Fl. Bras. Martii n. 305 (HB), which is very 

 well figured in Flor. Bras. tab. 63. Other specimens : Bahia, Luschnath 

 n. 120 (HB), Rio, Dr. Goldi (HG) - Riedel (HW). 



hi its typical form a very distinct species, distinguished by its nar- 

 row-linear pinnae (15 X IV2 cm.), incised about Y^ to the costae with 

 broad, patent, obtuse and obtusely dentated lobes with broad, open 

 sinuses between, by its dark-green colour, its large sori placed near to 

 the costule, and especially by its numerous and very large irregular pel- 

 lucid dots. Veins about 6, rather long. Scales few. 



A more developed form is 



var. denticulata (Fee) — fig. 6. 



Syn. Phegopteris denticulata Fee Crypt, vase. Bfes. 1: 100 tab. 32 

 fig. 2. 1869. 



Glaziou n. 2400 part. (HH), Riedel (HH) — Minas Geraes, prope 

 Ouro Preto, Schwacke n. 14599 (HG), prope Juiz de Fora, Schwacke n. 

 14793 (HG). Parahyba, Goldi (HG) - Rio, Goldi (HG). 



Pinnae broader (2—3^2 cm.) with longer, dentate and acute lobes; 

 sori more removed from the costule. The broadest form of this variety 

 approches very much S. caiidata, from which it can be distinguished by 

 its large immersed glands. 



Phegopteris hrevinervis Fee, Grypt. vase. Br. 1: 243 tab. 77 fig. 2. 

 1869, Glaziou n. 2400 part, (not n. 3333, which belongs to S. tijuccana) 

 is a form of this variety with almost entire lobes and occasionally ana- 

 stomosing veins, (fig. 7). 



5. Stigmatopteris nephrodioides (Kl.) — fig. 8. 



Syn. Pohjpodium nephrodioides Klotzsch, Linnaea 20: 384. 1847. 



Type from Colombia, Dr. Karsten n. 9 (HB). Similar plants from 

 Gosta Rica, Werckle 1904 (HG, HW) and Caracas, Lenormand n. 

 411 (HB). 



A very critical form, which seems specifically distinct from the 

 Brazilian species, although it shows no good character by which it can 

 be distinguished. It differs from S. tijuccana by its distinctly pellucid- 

 punctate lamina, rarely quite entire lobes and dark-green colour. From 

 S. prionites var. denticulata , which it resembles in general habit, it 

 differs by its oblique-falcate lobes and medial sori. 



A form intermediate between this species and S. ichtiosma was col- 

 lected by H. V. Tiirckheim; Guatemala: Alta Verapaz, Gubilquitz, n. II. 

 1432 (HW) ; it may be a new species.
