PAPUAN FERNS. 79 
3. A. papuanum Copel. spec. nova. 
Ehizomate repente, 1 mm crasso, viride, nigro-striato, j^aleis minutis 
sparsis; stipitibus 1 cm inter se distantibus, ca. 3 cm longis deorsum 
paleis minutis angustis vestitis; fronde ca. 15 cm alta, 25 ,mm lata, 
simplice^ acnmine obtuso producto, crenata, lierbacea, infra albida, glabra; 
venis obliquis^ remotis^ liberis; soris a costa fere ad marginem protensis; 
indusio lato pallido. 
This differs from most of the simple-leaved species in the very slender rhizome 
and herbaceous texture. It differs from A. comosum Christ of the same region 
in texture and size and in several details. A. concolor Hook., and A. amhoinense 
Willd. have stout rhizomes and tufted stipes. 
The spores are finely reticulate, and sparingly and irregularly tuherculale, 
but not spiny; which distinguishes it from several species of the group. 
4. A. tenerum Forst. var. acuminatum. 
No. 248. 
Polynesia to India. 
5. A. Kingii Copel, spec. nova. 
Euaspleninm, stipite alto^ 4 mm crasso^ sulcatOj sursum glabro, griseo- 
nigro ; fronde ultra 50 cm alta, pinnata ; pinnis utroque latere 5, infimis 
stipitatis furcatis, aliis subsessilibus integrisj ca. 20 cm longis^ ca. 5 cm 
latis^ abrupte acuminatis, basin versus (furcatis exceptis) aequalibus, 
obscure crenatis, herbaceis, glabris; venis furcatis; soris ca. 2 cm longis^ 
nee eostam nee marginem attingentibus ; indusio atro-brunneo^ angusto. 
No. 357, Lakekamu; No. 300 is an immature specimen of the same, the basal 
pinnae not forked. 
The spores have a hyaline cover, and are not spiny. The species is apparently 
very distinct, and easily re;;ognized by its large, broad, thin pinnae, even though 
the forking of the lowest is not constant. 
6. A. pellucidum Lam. 
No. 226,

7. A. macrophyllum Sw. 
No. 169, common on coast. 
Polynesia to the Comores.
