8. Asplenium nesioticum Maxon, sp. nov. Figure 4. 
An erect plant, with 6 to 9 linear rigid dark green fronds, 12 to19 cm. long. Rhi- 
zome short, decumbent or erect, 6 to 8 mm. in diameter, the upper part clothed with 
numerous narrowly lanceolate attenuate dark brown scales 3 to 3.5 mm. long; stipe 
2 to 4 cm. long, very dark purplish brown, sublucid, conspicuously alate (the wing 
yellowish brown, entire) and sparingly fibrillose with 
dark deciduous scales similar to those of the rhizome 
but reduced and finally filiform; lamina 10 to 16cm. 
long, 1.5 to 2 cm. broad, tapering in both directions 
(but more gradually below), the apex short-elongate, 
deeply crenate or lobate; pinne 18 to 25 pairs, 
sessile, coriaceous, opaque, nearly glabrous, with a 
few scattered whitish hairs below; characteristic 
middle pinne 8 to 12 mm. long, 3 to 5 mm. broad, 
horizontal, oblong, slightly curved, attached at the 
base of the inner margin, the base above subrec- 
tangular-auriculate, the margins elsewhere sinuate, 
obscurely or sometimes regularly crenate, the crena- 
tions most pronounced at the rounded apex, the 
lower margin usually sinuate only; lower pinne 
gradually much reduced, somewhat reflexed, distant, 
subtriangular or the lowermost suborbicular to fla- 
belliform, their base broadly cuneate, medial in 
attachment; rachis similar to the stipe, more widely 
alate, a few filiform scales borne at the base of the pinn; veins pinnate, the basal 
superior one 2 or 3-forked, the others simple or once-forked, the lower veins simple; 
sori elongate, linear, slightly curved, originating close to the midvein and always borne

of type specimen. Scale 2. 
’ This locality was originally published by the writer as follows: ‘Tufts under rocke, 
Cajon Pass (San Bernardino County,) near San Diego Mission, Nov. 9, 1857, Dr. New- 
berry.”’ The following note, received from Mr. S. B. Parish under date of August 17, 
1901, not only calls attention to a probable error but also gives interesting data as to 
the distribution of the species: 
“Permit me to call your attention to a confusion of localities in a citation under your 
character of Asplenium vespertinum, viz., ‘Cajon Pass (San Bernardino County,) near 
San Diego Mission.’ Cajon Pass, in this [San Bernardino] county, is 100 miles from 
San Diego; but there is a Cajon Valley about 20 miles from San Diego, and in that 
county, which is probably the place intended. Your species belongs to the Coast 
flora and is not rare on the seaward side of the Coast mountains. At Pasadenait reaches 
as you note, the San Bernardino range, as do many other of the Coast plants. One or 
two straggling specimens have been got near San Bernardino.” 
There can be little doubt that Cajon Valley is the correct locality. The old San 
Diego Mission referred to stood near the present city of San Diego.
