The Ferns of South Africa. 
7. Hymenophyllum lineare. Sw. 
Plate V. Natural size. 
Frond pinnate, elongating from the point, each season’s growth 
lanceolate in outline, widest at the middle, and tapering to both 
ends ; about three inches in length, and a half to one inch broad. 
Three to six of these season’s growths or fronds, placed one above 
another, are sometimes to be found, and, as they are very slender, 
wavy, and flaccid, they form a tangled mass in growth. Rachis 
not winged, but ciliated like the rest of the frond. Pinnae five to 
eight lines long, three lines broad, divided to a winged mid-rib, 
into three to seven simple, or forked, pinnules, which are oblong, 
one line broad, one to one and a half lines long. Pinnae closely 
set, more or less overlapping. Sori terminal on lower pinnules, 
with ciliated lobes. 
H. lineare. Swartz. Hk. and Bkr. Syn. Fil., 66. 
H. elegans. Spr. Hk. Sp. 1-91. 
H. trifidum. Hk. and Gr. Ic. Fil., t. 196. 
H. pendulum. Bory. 
H. capillare. Desv. Kuhn, Fil. Afr., 38. 
Found in Tropical America and Mauritius. I have seen no South 
African specimen, but Lady Barkly and Buchanan give “ Macamac, 
Transvaal Gold Fields, specimens recently sent by Mr. Ayres.” 
8. Hymenophyllum Tunbridgense. Smith. 
Plate IV. Fig 1. Natural size. c Do., grown in shade. b Pinnule and 
involucre, enlarged. 
Rhizome slender, . black, short jointed. Frond tripinnatifid, 
little more than a series of winged veins, very irregular in outline, 
often triangular, six to eight lines long, four to six lines broad, 
but frequently lanceolate or ovate-lanceolate, with the lower pinnae 
more or less reduced, and ranging up to four inches in length, one 
to one and a half inches broad. Stem not winged ; rachis narrowly 
winged in the upper half ; pinnae bipinnatifid, with a winged 
rachis, or in dwarf-grown specimens flabellate. Pinnules linear, 
one third of a line broad, strongly toothed. Sori on the lower 
pinnules of the mid pinnae, solitary, terminal on side pinnules.
