6. ALSOPHILA. 41 



47. A. lunulata, Br. ? Brack. ; st. and main rachises mucronato-asperous, pale 

 brown ; fr. ample, coriaceous, dark blackish-green, glabrous or very slightly 

 villous and bullato-squamulose on the costules beneath ; bi-subtripinnate ; 

 prim, pinnae 1^-2 ft. 1., 6-9 in. w. ; pinnl. oblong, subcaudato-acuminate, deeply 

 to the rachis pinnatifid ; lobes united or lower ones free ; lobes or ult. pmiiL 

 closely placed, 4 lines 1., 1-lj line w., oblong or linear-oblong, when fertile 

 falcate, acute, the margins refiexed and obscurely serrated in the upper half ; 

 veins forked below the middle ; sori copious, deep brown, nearer the costule than 

 the margin. HL Sp. Fil 1. p. 51. Brack. Fil. 1. p. 286. t. 39 (excellent}. 

 Polypod. For st. Cyathea Mertensiana, Bong, in Hb. Nostr. an Hemitelia crenu- 

 lata, Mett, (who quotes Alsophila extensa, BL, not .5r.) ? An etiam Hemitelia 

 Junghuniana, Mett., Alsophila, BL, Als. intermedia, Metten. ? 



Hab. "Pacific Islands," Forster ; Samoan and Fiji Islands, JBracJceniidge ; Isle of 

 Bonin, N. Caledonia, Aneiteura, M cGittivray ; Java?, Blume. Brackenridge gives 

 N. Zealand ; but I have never seen it from that country. This has much the habit of 

 our Cyathea affinis; but there is no trace of involucre. I think it is quite likely to be 

 the Polyp, lunulatum of Forster, and we have now happily a faithful figure given by 

 Brackeuridge.

48. A. alt-ernans, 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. 1-lJ in. L, 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. Polvpod.

Hab. Penang, WallicJi, 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-! aiwjeol ate, acuminate ; second, pinnl. linear-subfalcate, rather 

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

 furfuraceous, sparingly and slightly aculeated."- J!/e#. in Miq. Ann. Mus. Bot. 

 Lugd. 1. p. 26. Cyathea ? BL Hk. Sp. 1. p. 26. 



Hab. Celebes and' Ternate, Blume. 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 racfei sis muricated and furfuraceous ; tlie costa beneath 

 is shortly villous and furfuraceous ; and the general frond beneath ia "glauco-sericeous.'* 



50. A. wmosa, 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, pinnae 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. I. p. 53. t, 

 20. A. (excl. var. /3). 



Hab. Sylhet and Sincapore. 



51. A. contaminans, Wall. ; st. zndrachides " 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.
