60a. E»HEGOE'TERIS, rie. 



Sori roundish or obloug, rarely more than 2 X *s long as broad. Indusium 

 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 sectiom. 



§ 1. EUPHEGOPTERIS. Veins free. Sori round. Dififers 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.Pam., P, fig. 91, G. 



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

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

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



§ 4. STEGNOGRAMMA. Like § 3, but the sori linear or oblong, the opposite 

 pairs not confluent. Hk. Bk., I.e., tab. VI, fig. 52, b. 



§ 5. MENISCiUM. Like §§ 5 & 4, hut the sori mostly contiguous in pairs, 

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

 produced along the I'xcurrent veinlets. Bedd., I.e., tig. 231 — 234; Diels, 

 1. c., fig. 92, H. 



(*) Regarding ihis genus see the information in •Christ, Farnkr. d. Erde, 266". Its 

 natural place is near Dryopteris, from which il differs by the wanting indusium only. 

 A species of Dryopteris with fallen or oblileraled indusia is not or hardly drstingnishable 

 from this genus. .
