44. NEPHRODIUM, LASTREA. 261 



Hab. Chusan and Hong-Kong. This and the next differ from the rest of the group by 

 having a distinct terminal pinna similar to the lateral ones. In the others the apex of 

 the frond is pinnatifid. 



9. N. (Last.) Sieboldii, Hk. ; caud. tufted, with large brown lanceolate scales ; 

 st. 6-12 in. 1., scaly below ; fr. with an entire or slightly toothed lanceolate- 

 oblong terminal pinna 8-12 in. 1., 1^-2 in. br., and 2-4 similar ones on eacH 

 side, the lowest shortly stalked ; texture coriaceous ; rachis and both surfaces 

 naked ; veins in pinnated groups ; sori large, copious, scattered. Hk. Sp. 4. 

 p. 87. Fil. Ex. t. 31. Pycnopteris, Moore. 



Hab. Japan. Pinnae larger and fewer than in the last, and scales different. 



10. N. (Last.) hirtipes, Hk. ; st. tufted, 1 ft. or more 1., densely clothed with 

 long, blackish, fibrillose scales ; fr. 2-3 ft. 1., 8-10 in. br. ; pinnce 4-8 in. 1., 

 f-f in. br., with broad blunt lobes reaching from a quarter to a third down, 

 lower ones not reduced ; texture herbaceous ; rachises fibrillose like the stem ; 

 both surfaces naked ; veinlets 4-5 on a side ; sori medial. Hk. Sp. 4. p. 115. 

 t. 249. A. atratum, Watt. 



Hab. Himalayas (up to 6,000 ft.) to Ceylon, Malayan Peninsula and Isles. This con- 

 siderably resembles N. Filix-mas in general habit. 



11. N. (Last.) subbiauritum, Hk. ; st. 4-6 in. 1., jointed about halfway down, 

 firm, nearly naked ; fr. 12-15 in. 1., 4 in. br. ; pinnce close, spreading, the 

 longest 2 in. 1., \ in. br., the edge with shallow, blunt lobes, those on both 

 sides at the base larger than the others ; texture herbaceous ; rachis and 

 under side pubescent ; veins pinnate in the lobes, with 3-5 veinlets on a side ; 

 sori terminal on the veinlets. Hk. Sp. 4. p. 85. 



Hab. Bourbon. This comes nearest N. allopunctatum, and has similar white creta- 

 ceous dots above, and a jointed stem, so that it belongs to Arthropteris of J. Smith. 



12. N. (Last.) punctulatum, Baker ; rhizome wide-creeping ; st. 6-9 in. 1., dark 

 chesnut-brown, naked ; fr. 1 ft. or more 1., 4 in. br. ; pinnce 2-2% in. 1., f-f in. 

 br., bluntly lobed about a quarter of the way down in the lower part ; texture 

 coriaceous ; rachis and both surfaces naked, the upper marked with white 

 cretaceous dots ; veins in pinnated groups with 4-5 veinlets on a side ; sori 

 terminating lateral veinlets ; invol. distinctly stalked, persistent. 



Hab. Cameroon Mountains (4,500 ft.), 0. Mann. This has very distinct white dots 

 above, but the stem does not appear to be jointed. 



13. N. (Last.) macrotis, Hk. ; st. tufted, 12-18 in. 1., slender, pubescent ; fr. 

 18-24 in. 1., 8-10 in. br. ; pinnce 4-5 in. 1., f-f in. br., cut about a quarter of the 

 way down into blunt lobes, the apex acuminate, entire, the base with a large 

 auricle (J-J. in. 1.) on the upper side, all falcate, and the lower ones much 

 cleflexed ; texture herbaceous ; rachis and under side pubescent ; veinlets 3-4 

 on each side ; sori in rows near the main veins. Hk. Sp. 4. p. 86. t. 242. B. 



Hab. E. Peru, Spruce, 3979. In habit this is most like N. refractum, but different in 

 colour and clothing. The groups of veins join not urifrequently. 



*** Pinnce cut more than halfway down to the rachis into close, regular, entire, 

 or nearly entire lobes. Sp. 14-73. 



f Veinlets simple. Sp. 14-65. Involucre in many, but not all the species, thin 

 and fugacious. 



A. Group of N. patens. Lower pinnce hardly, if at all, reduced. Sp. 14-43. 



14. N. (Last.) subobliquatum, Baker; st. 12-18 in. 1., firm, erect, naked ; fr. 

 1^-2 ft, 1., 6-10 in. br. ; pinnce 3-5 in. 1., f-1 in. br., unequal-sided below, the
