44. NEPHROWUM, LASTREA. 281 



in. each way, deltoid, the lower pinna; much the largest .; lower pinnl. larger 

 than the others, which are oblong-lanceolate, acuminate, l|-2 in. 1., -|-f in. br., 

 cut down nearly to the rachis into close, oblong-lanceolate, crenated lobes ; 

 texture membranous ; rachises and under surface pubescent ; veinlets pinnate in 

 the lobes ; sori in rows not far from the midrib. Ilk. Sp. 4. p. 131. t. 260. 



Hab. Moulmein, Rev. C. S. Parish. Very different in texture from the rest of the 

 gioup, and, like species 71-2, approximating to some Sagenice in the sori being usually 

 terminal on branch veins. 



120. N. (Last.) subquinquefidum, Hk. ; st. 1 ft. or more 1., brownish, firm, 

 naked or villose upwards ; fr. 6-18 in. each way ; lower pinnae much the largest, 

 with the pinnl. on the lower side much larger than the others, which are 1-3 

 in. 1., f-1 in. br., often cut down nearly to the rachis below into broad, oblong 

 lobes ; texture herbaceous ; colour dark-green ; rachis more or less villose ; sori 

 medial. Hk. Sp. 4. p. 130. N. Vogelli, Hk. 2nd Cent. t. 21. N. funestum, 

 Hk. Sp. 4. p. 129. t. 259. /3, N. variabile, Hk. ; more compound ; lower pinnce 

 sometimes 1 ft, 1., quadripinnatifid, with lowest segm. 1 in. 1., ^ in. br. Hk. Sp. 4. 

 p. 140. L. pilosissima, J. Sin. 



Hab. West Indies to Brazil, island of Nissobe, Angola, Guinea Coast, Senegambia. 

 The extremes differ widely in cutting, but pass into one another very gradually. A. aero- 

 carpon, Fe"e, belongs here, and fraternum, securidiforme, and lanigerum of ELuhn. The 

 oldest name is protensum, Afzelius. , 



121. N. (Last.) subsericeum, Baker; rhizome clothed with lanceolate, ferru- 

 ginous scales ; st. 7 in. L, fr. 8 in. L, deltoid, tripinnatifid ; lowest pinnce 

 ovate-lanceolate, unequal-sided ; pinnl. ovate-rhomboidal, obtuse, cut down to a 

 narrow wing into toothed or pinnatifid segm. ; texture thin, flaccid ; both sides 

 slightly and the midrib above densely clothed with soft spreading hairs ; sori 

 1 to each lobe. Aspid. Mett. Fil. Nov. Cal. p. 74. 



Hab. New Caledonia, Vieittard. 



122. N. (Last.) decompositum, R. Br. ; rhizome wide-creeping ; st. 12-18 in. L, 

 scaly only at the base, firm, villose ; fr. 1-2 ft. 1., 1 ft. or more br., ovate-lan- 

 ceolate or deltoid ; lower pinnce much the largest, deltoid, 4-9 in. 1., 2-4 in. br. ; 

 pinnl. lanceolate, more or less deeply pinnatifid ; segm. unequal-sided, ovate- 

 rhomboidal, deeply pinnatifid, with toothed lobes ; rachis and under side more or 

 less villose ; sori rather large, placed midway between the midrib and edge. 

 (3, N. glabcllum. A. Cunn. ; rhizome abbreviated ; fr. more finely cut, with more 

 copious spinulose teeth, villose only on the rachis above, the surfaces glossy, and 

 lobes not imbricated. Hk. Sp. 4. p. 146. 



Hab. Australia, Van Diemen's Land, and New Zealand to Tahiti and Fiji. Very 

 variable in size, texture, and cutting. Dr. Mueller sends a form with suppressed invo- 

 lucres. A. Shepherdi, Kze. (L. acuminata, Moore), is most like a. in cutting, but the 

 rhizome is abbreviated and the frond narrower. 



123. N. (Last.) vehitinum, Hk. fil. ; st. 1 ft. or more 1., bright-brown, villose 

 upwards, scaly only at the base ; fr. 12-18 in. 1., by nearly as broad, deltoid ; 

 lower pinnce much the largest, deltoid ; lowest pinnl. larger than the others, 

 which are close, lanceolate, cut down to the rachis below into pinnatifid, oblong- 

 lobes ; texture herbaceous ; rachises densely villose, and both sides softly pubescent ; 

 sori small, copious ; invol. gland-ciliated. Hk. Sp. 4. p. 145. 



Hab. New Zealand. Principally distinguished from the preceding by its more flaccid 

 habit and densely villose surface and rachises. We have similar but not quite identical 

 plants from Queensland and Fiji. 



124. N. (Last.) recedens, Hk. ; st. about 1 ft. 1., erect, villose, soft, clothed at 

 the base with squarrose linear scales ; fr. li-2 ft. L, 1 ft. or more br., deltoid ;
