upper dark green and shining; rachis and costae slender, 
glabrous beneath, puberulous above, the latter slightly wavy; 
veins oblique, simple or forked, pellucid, raised and con- 
spicuous above, obsolete or obscure beneath; sori small, 
ose to the margin; involucre small, fugacious; capsules ciliate, 
Nephrodium Sprengelii, Hook., var. persicinum, 
- Jenman; growth coarser than in the type, the nascent fronds 
thiekly coated with mucous, viscid throughout when mature, 
strongly peach-scented; margins inflexed, nearly enclosing 
the sori. 
Nephrodium Sherringii Jenman, n. sp. — Caudex 
erect; stipites caespitose, very short, scaly; fronds ereot, 
lanceolate or ovate-lanceolate, acuminate, fully pinnate to 
the very apex, 2 to 3 feet long, 10 to 14 inches wide; pinnae 
copious, spreading, dwindling down gradually to mere seat, 
ments at the base, quite sessile, largest 6 to 8 inches long, 
1'/a to 2 inches wide, acuminate, cut down to the narrowly 
winged costae into ligulate, bluntish or acute, subentire 
toothed or deeply-lobed pinnules, which are 'J; to 1*J, inch 
long, 2 to 3 lines wide, with a rounded open sinus between 
them, the inferior one on the lower side producing a small 
auricle which overlaps the rachis; texture chartaceous; colour 
light green; both surfaces, with the rachis, puberulous- 
glandulose; cortex finely ciliate above, the edge of the margins 
obscurely cartilaginous-toothed; veins pellucid, about 16 to 
a side, simple, forked, or pinnate; sori small, one to each 
branch, medial, or nearer the edge; involuere persistent, 
 glandulose. 
Nephrodium Jenmani, Baker, var. sitiorum, Jen- 
man: stipes and rachis slender; pinnae in opposite, patent 
pairs, narrow, and diminishing gradually from the base out- 
wards, the acuminate attenuated apices usually entire; basal 
pinnules enlarged and increasing in size as the pinnae dwindle 
to mere auricles at the base of the stipes; veins evident on 
‚the upper side; sori hardly medial. 
Nephrodium usitatum, Jenman, n. sp. — Caudex 
‚stout, erect, often a span or more high; stipites caespitose, 
strong, numerous, 9 to 16 inches long, clothed at the base 
_ (and a few scattered upwards) with deeiduous, dark, dull 
brown scales; fronds pinnate, 18 inches to 21) feet long, 
9 to 12 inches wide, apex acuminate, pinnatifid and passing 
through mere lobes into the serrate attenuated point; pinnae 
_ numerous, but distant, spreading horizontally, 4 to 6 inches 
long (variable in width) ®, to 1 inch wide, the lowest one 
to two pairs little or hardly reduced, and sometimes narro- 
_ wed at the base, upper ones sessile, truncate; point finely 
acuminate, serrato-entire, within cut a third or rather more
