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, acumine obtnso producto, crenata, herbacea, infra albida, glabra ;

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. amboinense 
Willd. have stout rhizomes and tufted stipes. 
The spores are finely reticulate, and sparingly and irregularly tuberculate, 
but not spiny; which distinguishes it from several species of the group. 
4. A. tenerum Forst. var. acuminatum. 
No. 2^8.

5. A. Kingii Copel. spec. nova. 
Euasplenium, stipite alto, 4 mm crasso, snlcato, sursum glabro, griseo- 
nigro; fronde ultra 50 cm alta, pinnata; pinnis utroque latere 5, infimis 
stipitatis furcatis, aliis subsessilibus integris, 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, 
nec costam nec 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 recognized by its large, broad, thin pinnae, even though 
the forking of the lowest is not constant.
