§ 3. GONIOPHLEBIUM. Veins forming 1 or more rows of regular areolae ± 

 as in Nephrodium, each with a simple or rarely forked, included, excur- 

 rent free veinlet. Sori terminal on the included veinlets, commonly in 

 the costal areolae only. Hk. Bk., 1. c, fig. 48, h; Dielsl. c. fig. 163, B &D. 

 a. Crypsinus. Fronds simple. (Not in Malaya). 

 h. Synammia. Fronds pinnatifid. (Not in Malaya). 



c. llarginaria. Fronds pinnate; pinnae hroadly adnate to the 

 rachis. 



d. Scbellolepis (Schellopsis). Fronds pinnate; at least the lower 

 pinnae + stalked, or sessile with a cuneate to truncate, not adnate 



§ 4. PHLEBODIUM. Veins forming more or less regular areolae, each with

 § 5. CAMPYLONEURON. Main vains connected hy parallel, straight or curved, 

 transverse veinlets forming regular, subquadrangular areolae, each with 

 commonly 2 or more included, excurrent free veinlets. Sori suhterminal 

 on the free veinlets, 1 to each. Hk. Bk., 1. c, fig. 48, j; Diels, 1. c, 

 fig. 163, H. (Not in Malaya). 

 § 6. PLEOPELTIS. Veins anastomosing commonly more or less copiously,

 growths. Rhizome-scales present. Diels, 1. c, fig. 166, D — E. 



♦+. Liccanopterls. Sori on marginal tooth- or lobe-like outgrowths,
