= .-— 
euneately cut away on the lower side at the base. Ulti- 
mate lobes subremote, ligulate or rather broader towards 
the truncate tip, one-eighth to one-sixteenth of an inch long, 
one-quarter to one-third of a line broad, with only a single 
central vein, the tip denticulate. Sori minute, oblong, usu- 
ally immersed in the tip of the segments, rarely free and 
terminal. Involucre free at the end only. : 
Lindsaya Jamesonioides, Baker, n. sp. Rhi- 
zome short-ereeping, as thick as a quill, elothed with minute 
subulate rigid nearly black scales. Stipes wiry, nearly black, 
one to three inches long. Fronds linear, simply pinnate, 
three to five inches long, under half an inch broad, com- 
posed of sessile contiguous roundish alternate deciduous entire 
pinnae one-sixth to one-fifth of an inch broad, those of the 
upper third of the frond growing gradually smaller. Rachis 
 wiry, dark chestnut-brown. Veins quite hidden, Texture 
rigidly coriaceous; both surfaces quite free from hairs or 
scales, the upper side much wrinkled. Sorus continuous 
round all the pinna except its base. Inner valve of the in- 
 volucre equalling the outer, broad, chartaceous, persistent 
glabrous. 
‚ Lindsayacrispa, Baker, n.sp. Caudex short-eree 
ping. Stipe wiry, naked, castaneous, one to nine inches 
long. Lamina simply pinnate, lanceolate, about half a foot 
long, half to three-quarters of an inch broad. Pinnae not 
erowded, all sessile, dimidiate-deltoid, truncate and entire 
on the inner and patent or erecto-patent lower edge, Irre 
gularly ineiso-crenate on the upper one, glabrous, bright 
‚green, membranous in texture, with the free very distinetly 
marked flabellate veins radiating from the inner half of the 
lower edge. Involucre undulated, with two distinet nearly 
equal cartilaginous valves, — Habit of the small tender 
forms of Adiantum caudatum, but the fronds neither 
at all hairy nor rooting at the tip. E 
Pteris quadriaurita, Betz., var. digitata, Baker. 
A digitate form, like the Indian P. Govilleans, Wall, 
but the barren and fertile fronds not dimorphie. The tet 
ture firmer than usual. The rachis with a broad wing, 
in P. biaurita, and the veins crowded and obscure. 
Asplenium (Diplazium) Porphyrorachis, Baker: 
Caudex suberect, produeing many short-stiped barren front 
to a few long-stiped fertile ones. Stipes purple, of the bar 
ren frond two to three inches, of the fertile six to twelve 
 inches long, clothed throughout with spreading black linear- 
subulate paleae. Frond lanceolate, six to twelve inches long, 
one to two inches and a half broad, cut down througho
