47. A. lunulata, R. Br. ; fr. ample, tripinnate; rachises stramineous, glabrous 

 below, densely muricated ; pinnce oblong-lanceolate, 1^-2 ft. 1. ; pinnl. close, 

 ligulate, sessile, 4-5 in. 1., f-1 in. br. ; segm. close, ligulate falcate, blunt, 1 lin. 

 br., obscurely crenulate ; texture subcoriaceous ; both sides green, glabyous, the 

 midrib below naked or obscurely furfuraceous ; veins distinct, crowded, 10-12-ju- 



fate, deeply forked ; sori minute, subcostular, recept. densely pilose. Hk. tip.

Hab. Polynesia. From the common Viti plant, as described, the following are dis- 

 tinguishable : intermedia, Mett., N. Caledonia, segments broader, veins and sori more 

 distant ; Bongardiana (Mett.), Bonin, segments broader, entire, rather glaucous below, 

 with copious scattered scales, veins more distant and obscure ; vitiensis, Carruth., Viti 

 and Samoa, texture more rigid, veins and sori more crowded, midribs below densely 

 scaly ; Veitchii, Baker, Aneitum, texture less coriaceous, veins less distinct, segments 

 narrow, subacute, densely scaly on midribs beneath.

48. A. alternans, Hk. ; rachis much thicker than a swan's quill, glabrous, 

 smooth, tawny-brown ; fr. ample, subcoriaceous, glabrous, subtripinnate ; prim, 

 pinnce short-petiolate, very remote, 10-14 in. 1., 2-3 in. w., oblong, acuminate, 

 deeply pinnatifid, pinnated near the base ; lobes or pinnl. l-l in. 1., oblong, 

 acute, subfalcate, entire or serrate, all horizontal, the extremity of the frond 

 suddenly pinnated with oblong, undivided, sessile pinnl., serrated at the margin; 

 veins approximate, once or twice forked ; sori subbiseriate on each pinnl. or 

 lobe, subglobose, compact, mixed with rather copious jointed hairs. Polypod.

Hab. Penang, Wallich, Sir W. Norris. In the figure above quoted, a depression 

 formed by the sorus on the lobe was mistaken by the artist for an involucre. 



49. A.? celebica, Mett.; "fr. tripinnate, coriaceous, glauco-sericeous beneath ; 

 pinnl. linear-lanceolate, acuminate ; second, pinnl. linear -subfalcate, rather 

 obtuse, crenulate at the apex, truncate and sessile at the base ; common rachis 

 furfuraceous, sparingly and slightly aculeated." Mett. in, Miq. Ann. Mus. Bot.

Hab. Celebes and Ternate, flume. A. sterile fragment of this (and but little 

 more seems to be known) I owe to Dr. Blume. Its characters, such as they are, 

 depend on the adventitious clothing : the rachis is muricated and furfuraceous ; thecosta 

 beneath is shortly villous and furfuraceous; and the general frond beneath is "glauco- 

 sericeous." 



50. A. comosa, Hk. ; unarmed ; st. paleaceous with long linear - subulate 

 scales, pale brown, as well as the rachises, which are tawny-villous on the upper 

 side ; fr. herbaceous, yellow-green, glabrous, and scaleless ; prim, pinnce 14-16 

 in. 1., 6-8 in. w. ; pinnl. oblong-acuminate, from a rather broad and truncated 

 sessile or shortly petioled base serrated f of the way to the costule, pinnatifid 

 with very narrow sinuses ; lobes close - placed, oblong - serrated ; veins rarely 

 forked ; sori orange-colour, rather distant, between the costule and the margin, 

 nearer the latter, receptacle small, very slightly elevated. Hk. Sp. 1. p. 53. t. 

 20. A. (excl. var. /3). A. squamulata, Mett. A. oligosora, Kunze. 



Hab. Sincapore and Malay Isles. 



51. A. contaminans, Wall. ; st. and rachides " paleaceous at the base," purplish- 

 brown, glossy, aculeate with short prickles tipped with a gland ; fr. ample, 

 coriaceous, glabrous, black-green above (when dry), glaucous beneath : prim.
