Rhizome short-creeping, densely scaly; scales brown, lanceolate-subulate, 
entire; frond rather approximate, stipe 6-20 cm long, light castaneous, some- 
what glossy, naked throughout, lamina 15-25 cm long, impari-pinnate or rarely 
simple (Lindsaya G'riffithiana); pinne 1-12-jugate, petiolate or subsessile, alternate, 
6-13 cm long, from less than 1 cm to 2 cm broad, linear-lanceolate, base obliquely 
truncate, both sides glabrous; texture thin herbaceous, margin entire (sterile ones 
serrate); midrib prominent, lateral main veins none; veins anastomosing in 1-2 rows 
of oblique, angular exappendiculate areole on each side of midrib, free towards 
margin; sori linear, continuous, uniting the apices of free veinlets, indusium double, 
membranaceous, gray, entire, continuous, opening outwardly; spores 4-angular,

Widely distributed throughout tropical Asia, Australia and Polynesia. 
Very closely related to this fern is Sch. heterophyllum (Dry.), which differs in the 
lateral pinne gradually decrescent towards the lobato-pinnatifid apex. Our fern 
is a very variable one as to the shape of frond, which varies from simple to fully 
pinnate with 10 pairs of pinne of different width. Our plate is based upon a speci- 
men from Kwangtung (leg. N. K. Chun 40990), which agrees very well with type 
from Island Maritius, now io be found in the herb. Swartz.
