4Sft. SOHIZOSTEGE, Uillebfand. 



Sori roundish, submarginal, on terminal ~]~-shaped expansions of the 

 veins or veinlets or uniting the apices of the fork bi*anches of forked veins. 

 Indusium of the same shape, remarkably broad. Spores tetrahedral. 



Rhizome erect. Stipes not articulate to the rhizome, with a single [_J- 

 shaped vascular strand. Fronds divided; veins free or joining. 



Hawaii, Mindanao. 



X. Pinnae pinnalifid ^j^-way down to the costa, the segments entire. 



(1) S. pachysora. 

 x.x. Pinnae pinnalifid nearly or quite to the costa, the segments cretiafe or lobed. 



(2) S. calocarpa. 



(1) S. pachysora, Copel., Philipp. Journ., I, Suppl., 153. 

 Rhizome short, erect, thick, crowned with fuscous, lanceolate scales. 



Stipes tufted, ± 30 c.M. long, yellow-fuscous, clothed with scales of the same 

 colour. Fronds i 40 c.M. long, ± 20 c.M. broad, 2-pinnatifid. Lowest 

 pinnae somewhat deflexed, + 10 c.M. long, sessile, forked at the base on the 

 lower side, the branches subacute, cut ^/4-way down to the costa into entire, 

 obtuse lobes S — 10 m.M. long, 5 — 7 m.M. broad, central pinnae similarly 

 pinnalifid, decurrent, nearly confluent, the higher ones gradually reduced. 

 Texture carnoso-subcoriaceous ; surfaces naked ; veins hidden, joining in 1 row 

 of costal areolae, rarely forming a second row of areolae in the segments. Sori 

 solitary on the vein tips, free or confluent. 

 Mindanao. 



(2) S. calocarpa, Copel., Philipp. Journ., I, Suppl, 155, tab. XII. 

 Like S. pachysora, Copel, but: Fronds 35—40 c.M. long, + 20 c.M. 



broad, acute, 2-pinnate or sub-2-pinnale. Lower pinnae oblique, deltoid, the 

 following lanceolate, 10 c.M. long, + 3 c.M. broad, acuminate, cut down 

 nearly or quite to the costa. Secondary segments + 15 m.M. long, ± 4 m.M. 

 broad, decurrent, crenale or cut '/j'^^'^Y down to the costula. Texture carnoso- 

 coriaceous; main rachis cinereous, marginate; veins free. Sori not confluent.
