Sori roundish or oblong; rarely more ihan 2 X ^s long as broad. Indusiuni 

 wanting. 



Rhizome creeping or erect. Stipes not articulate to the rhizome. Fronds 

 various in size and shape, commonly with the habit and appearance of Dry- 

 opteris; main veins pinnate; veins free as in Lastraea or anastomosing as in 

 Nephrodium. (Dryopteris, p. p., C. Chr., Ind. Fil.). 



Tropical and subtropical, also found in cooler climates. (*) 



Arrangement of the sections. 



$ l.EUPHEGOPTERIS. Veins free. Sori round. Differs from Lastraea by 

 the absence of an indusium. Bedd., Handb. Ind. Ferns, fig. 148 — 152. 



§ 2. LEPTOGRAMMA. Like § 1, but the sori linear or oblong. Diels, in 

 Engl. & Prantl, Nat. Pfl.Fam., P, fig. 91, G. 



§ 3. GONIOPTERIS. Opposite veins of contiguous groups uniting as in Ne- 

 phrodium. Sori round, free. Differs from Nephrodium by the absence of 

 of an indusium. Ek. Bk., Syn. Fil., tab. V, fig. 4->, e. 



§ 4. STEGNOGRAMMA. Like § 5, but the sori linear or oblong, the opposite 

 pairs not confluent. Hk. Bk., 1. c, tab. VI, fig. 52, b. 



§ 5. MENlSCiUM. Like §§ 3 & 4, but the sori mostly contiguous in pairs, 

 at least the lower (sometimes the higher) pairs confluent and not rarely 

 produced along the excurrent veinlets. Bedd., I.e., fig. 231 — 234; Diels, 

 1. c, fig. 92, H.

*.;ti. Sori oblong, sometimes linear. § 2. LEPTOGRAMMA. 



(*) Regarding this genus see the information in "Christ, Farnkr. d. Erde, 266". [ts 

 natural place is near Dryopteris, from which it Jiflers by the wanting indusium only. 

 A species of Dryopteris with fallen or obliteraleil indusia is not or hardly distinguishable 

 from this genus.
