844 ON A SECOND COLIBCTION OF FERNS FROM SAMOA. 



quadripinnatifid. Rachises naked, glossy, pale bro-wn. Pinna? 

 oblonp-lanceolate, reaching a length of H-2 feet and a breadth 

 of 8-10 inches. Pinnules lanceolate, 12-15 lines broad, cut 

 down to a narrow wing into deeply pinnatifid spaced lanceolate 

 tertiary segments ^ inch broad. Veins sparingly pinnate in the 

 quaternary lobes. Texture moderately firm ; both surfaces quite 

 naked. Sori oblong, subcostal, half a line long, usually one 

 only at the base of each quaternary segment. Involucre firm, 

 persistent, glabrous. Like the Philippine A. u'oodirardioides, 

 Baker, in sori and texture, but the lamina much larger and more 

 compound. 

 88. Aspleniiim (Diplazium) maximum, D. Don. 



184. Allantodia Brunoniana, Wall. 



203. Aspidium aculeatum, Siv. 



224. var. samoense, Luerssen. 



201. Nephrodium hirtipes, Hook. New to Polynesia. 



202 (17*). (Lastrea) pubirachis, Baker, n. sp. Caudex erect. 



Stems densely tufted, pilose, clothed, especially in the lower half, 

 with many large lanceolate pale brown membranoiis scales. 

 Frond oblong-lanceolate, bipinnate, 8-10 inches long by 

 4-5 inches broad, not reduced at the base. Pinnae lanceolate, 

 2-2^ inches long, -^-l inch broad, sessile, cut down to the rachis 

 into close ligulate sub-entire or toothed obtuse segments under 

 ^ inch broad, the lowest pair of pinna? much deflexed. Texture 

 moderately firm, the rachises pilose and rest of the surfaces 

 naked. Sori copious, medial. Veins simple, 6-8-jugate. In- 

 volucre firm, persistent, glabrous. Closely allied to N. chryso- 

 lobum of Tropical America. 



50. Nephrodium davallioides, Baker. 



212. pteroides, /. Sm. 



211. Haenkeanum, Pre.sZ. ? Small variety. 



204 (50*). PoLTPODiUM (Phegopteris) peesimile, Baker. Frond 

 ample, bipinnate. Rachises stramineous, finely pubescent. Pinnae 

 oblong-lanceolate, reaching a foot long, 3-4 inches broad. Pin- 

 nules lanceolate, sessile, cut down to the rachis into close ligulate 

 obtuse tertiary segments ^ inch broad. Veins pinnate in the 

 tertiary segments, with many erecto-patent forked veinlets. 

 Texture membranous ; both surfaces bright green, finely pilose. 

 Sori small, round, placed nearer the edge than the midrib, 

 many to each tertiary segment. Texture and cutting very like 

 those of JVcphrodhim Bori/antim. 



222 (103*). PoLTPODiCM (Eupolypodium) savaiense, Powell in litt., 

 n. sp. Caudex erect. Stems tufted, an inch long, clothed with 

 soft short spreading brown hairs. Frond ligulate, entire, 

 5-6 inches long, under half an inch broad, narrowed gradually 

 from the middle to both ends. Texture membranous ; surfaces 

 slightly hairy. Veins distinct, erecto-patent, the central ones 

 with 2-3 ascending branches on each side, which fall short of the 

 edge and end in sori. Sori minute, round, superficial, irregu- 

 larly biserial, none near the midrib, but all medial and intra- 

 marginal. Sent also by Mr. Powell a few months ago under the 

 name which I have adopted.
