590 FILICES. [ Asplenium. 
Synops. Fil. p. 202. — Is by many recent writers united with A. lunula- 
tum, Sw. 
Not uncommon in woods of the lower region on all islands! — The species is distri- 
the occupy the anterior branches of forked veins and are at some distance from the 
costule, while in the others they descend from the anterior roeieial he to the trunk of the 
vein and touch the costule. 
8 var. abla —- Whole plant only 4—6‘ long, on a caudex of 
2'/2', Pinnules 3“ < 2”, the upper ones almost dimidiate, as in A. nor- 
male, but with a aah margin to the pale rhachis and stipes. 
x var. subbipinnatum. — Size of «4. Frond chartaceous, darker. Pinnae longer 
and more or less deeply cut into oblong, or cuneate- ena , or bi-, tridentate 
segments and an almost free auricle, which is cuneate-obov a and ob- 
tusely 3—7-toothed. Sori single and marginal in be simple and bidentate 
segments, 2—3—5 in the larger segments. — Of this too we have a small- 
leaved form, the largest pinnae only 3" long. 
Oahu akaleha; Kauai! Waimea and Halemanu (Kn.).—In some Kauai specimens 
eee othe segments besides the basal one are obovate, with pinnae veins, thus forming 
a close approach to A. gracile, Pappe and Rawson, from 8. Africa 
6 var. Macraei. — Caudex, stipes and shape of frond as before, the latter 
10—16‘ X 11/2—3‘, subchartaceous, bipinnate. Pinnae 20—30 on a side, 
patent, on stalks of !/2—1“, obliquely ovate to ovate- isle somewhat 
obtuse, cut down = a margined rhachis on each side into 7—10 oblong 
cuneate and obovate pinnules, of Fea the upper basal one is the largest 
and 4—5-cleft, the following being 3—2-cleft to entire and falcate; the 
lower basal pinnule opposite the second upper one. Veins pinnate in 
the inner, repeatedly forking to simple in the outer pinnules. Sori 3—5 
pinnate in the auricle, 3—1 in the following, and marginal (dareoid) in 
the entire pinnules, ene saa ie the midrib and often curved. Invol.
