Natal. — Grey town to Drakensberg (Wood), not under 3000 feet alt. 
(Buchanan). 
Genus IX. — Lindsaya. Dryand. 
Small herbaceous ferns, having linear marginal sori, covered by 
a membranous indusium attached a little within the margin, so 
that it equals the edge of the frond, and opens outward like a slit 
along the margin, at the bottom of which, all along, is the recep- 
tacle. Several species occur in Madagascar and Mascerenes. 
20. Lindsaya ensifolia. Swartz. 
Plate XIV. Natural size. b Section of pinna, magnified, 
c Part of sorus, much enlarged. 
Rhizome very short and thick, with lanceolate scales. Stipe 
three to nine inches long, round, glabrous. Frond six to fifteen 
inches long, glabrous, firmly herbaceous, simply pinnate, with one 
to six pairs of pinnae, and a long terminal one. Pinnae equal sided, 
three to six inches long, a quarter to half-inch broad, linear or 
linear-lanceolate, tapering shortly to the point, and to the slightly 
stalked base, but otherwise of very equal width. Barren fronds, 
and the barren tips of fertile fronds, slightly toothed ; fertile parts 
more or less contracted. Sori continuous along most of the fertile 
pinnae. Veins uniting freely and forming numerous irregular 
areolae. 
This has the habit of Pteris cretica, but with the sori opening 
outward.
