44. NEPIIRODIUM, §LvSTREA. 201 



TTab. Cliui3aii and Hong-Kong. — This and tlie next differ from the rest of the group l)y 

 having a distinct terminal pinna similar to the hiter.al ones. In the others the ajjex of 

 the frond is pinnatifid. 



!). N. (Last.) Sieholdii, Hk. ; caud. tufted, with large brown lanceolate scales ; 

 St. (5-12 in. 1., scaly below ; fr. with an entire or slightly toothed lanceolate- 

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

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

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

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



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



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

 long, blackish, fibrillose scales ; fr. 2-3 ft. 1., 8-lG in. br. ; ^wn^o? 4-8 in. L, 



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

 ower ones not reduced ; texture herbaceous ; rachises fil)rillose like the stem ; 

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

 t. 249. A. atratura, Wall. 



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

 Biderably resembles N. Filix-mas in general habit. 



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

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

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

 siiies 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. alhopunctaium, and has similar white creta- 

 ceous dots above, and a jointed stem, so that it belongs to Arthrojateris 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. ; pinnai 2-2^ in. 1., |-| in. 

 br., bluntly lobed about a quarter of the wa}' 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.), G. 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. ; pinnae 4-5 in. L, |-| in. br., cut about a quarter of the 

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

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

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

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



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

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



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

 or nearly entire lobes. Sp. 1^73. 



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

 and fugacious. 



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



14. N. (Last.) subobliquatum. Baker; s«. 12-18 in. 1., firm, erect, naked ; />•. 

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