coriaceous texture, as if, wlion fresli, it were carnose, wlien dry, turning hrown, 

 and very opaque. Gaudicliaud says very justly, " Les fructifications sont con- 

 fluentes, tres-noiubreuses." Tliey are on every pinnule and segment, often im- 

 bricating and lying quite parallel with the rachis, a closely compacted row on 

 each side. 



175. A. (Euasplenium) dissectum, Brack.; caudex "glo- 

 bose," stipes nearly a span long fugaciously setose as is the 

 clianneiled main racliis, frond a foot and more long in our 

 specimens (15-18 inches, Brack.) ovate acuminate 3-4-pin- 

 nate coriaceous dark-brown and opaque when dry, primary 

 and secondary pinmc petiolate rather distant, tertiary pinnae 

 of 3 or 4 pinnules which are cuneato-lanceolate acute some- 

 times again pinnate ultimate ones one-third of an inch long 

 entire or bi-trifid segments linear-acute, veins solitary central 

 forking below each dichotomy, sori solitary where the veins 

 are so, geminate on a fork and opening towards each other.

Hal). Sandwich Islands; forests of Hawaii, Douglas, n. 47, Brac/cenridge. — At 

 first sight this has some resemblance to Jspl. Ad. nigrum ; but it is very different 

 in ramification and pinnules and segments, much more copiously divided, rarely 

 bearing more than one sorus on a pinnule or segment, and never more than two. 

 Brackenridge (whose figure, taken from a very fine specimen, is excellent) com- 

 pares it with A. patens, Kaulf. (not Gaudicb.), which is a form oilaserpitiifolium. 

 a very different sjjccies. 



176. A. (Euasplenium) JVardii, Hook.; caudex stout ho- 

 rizontal above densely clothed with long subulate finely 

 acuminate chaffy scales nearly half an inch long, stipes (ap- 

 parently solitary) about a span long with a few similar 

 ferruginous scales at the base stramineous glossy grooved on 

 the anterior side as is the rachis, frond 12-14 inches long by 

 10 broad flaccid deltoid acuminate meml)ranaceous dark 

 olive-green when dry opaque (not glossy) bipinnate, pinnae 

 horizontal petiolate lanceolate the largest G inches long acu- 

 minate (the acutninated apices pinnatifid), pinnules approxi- 

 mate 6-8 lines long horizontal sessile sul)dimidiato-ovate 

 obtuse entire or slightly sinuate the superior base truncated 

 subauricled, inferior base a little decurrent upon the rachis 

 terminal larger than the rest, lower pinnules an inch long 

 lobato-pinnatifid with rounded lobes more distinctly auricled 

 sometimes .3-toothed at the apex, veins pinnated obliquely 

 patent simple or once or twice forked, sori oblong 4-6 on 

 each pinna in two rows near the costa, involucres very thin 

 and membranaceous almost white. — Hook, in 2nd Cent, of 

 Ferns, t. 33.
