THE FLORA HONGKONGENSIS. 141 
in A. coniifolium, Wall. A. lacerum, Sw., referred to A. filix- 
mas by Sir W. Hooker, appears to me a well-marked plant, with 
a not very distant relationship to A. acrostichoides, Sw. The 
inconstancy of form of the indusium in most of the species 
of this group sufficiently shows how unstable a genus Nephro- 
dium is, though retained by both Hooker and Baker. It is, in 
fact, not a natural subgenus or section; for its adoption as such 
removes allied species to a distance from each other. 
68. Aspidium amabile, Blume; Hook. Sp. Fil. iv. 25, t. 225. 
I have specimens from the mainland immediately opposite 
Hongkong, where I believe it occurs also. A native likewise of 
Nipal, Ceylon, the Malayan isles, Formosa, and Japan. 
*Aspidium uliginosum, Kze.; Mett. Fil. Hort. Lips. 94. (=Poly- 
podium tenericaule, Wall.; Benth. Fl. Hongk. 459.) 
*Aspidium calcaratum, Blume. (=Nephrodium calcaratum, Hook. Sp. 
Fil. iv. 93.—Aspidium ciliatum, Wall.; Benth. Fl. Hongk. 455.) 
*Aspidium glanduligerum, Kze.; Mett. Monogr. Aspid. 86. (=A. 
Thelypteris, Benth. Fl. Hongk. 475, but not of Linneus.—Nephro- 
dium gracilesenes, Hook. Sp. Fil. iv. 93, but not Aspidium gra- 
cilescens of Blume.) 
69. Aspidium sophoroides, Sw.; Mett. in Mig. Ann. Mus. Bot. Lugd.- 
Bat.i.231. (=Nephrodium sophoroides, Desv. ; Bak. Syn. Fil. 289.) 
Not very common. Extends along the coast of China, and 
occurs also in Formosa, Loochoo, and Japan. 
*Aspidium latipinna, mihi. (=A. molle y. paucisorum, Hook. and 
Arn. Bot. Beechy, 256.—A molle, var. latipinna, Benth. Fl. Hongk. 
455.—Nephrodium latipinna, Hook. and Bak. Syn. Fil. 392.) 
Common in the island and, as I can testify from many years' 
observation, very constant in character, so that I have never 
seen reason to doubt its specific rank. Occurs also on the main- 
land, and in Java. 
70. Aspidium heterocarpon, Blume; Mett. in Mig. Ann, Mus, Bot. 
Lugd.-Bat. i. 233. 
Oceurs also in Java, Sumatra, and Borneo. 
*Aspidium subtriphyllum, Hook. Sp. Fil. iv. 52. (=Polypodium 
subtriphyllum, Hook. and Arn. Bot. Beechey, t. 50.—Aspidium tri- 
foliatum, Benth. Fl. Hongk. 454, part., but not of Swartz.) 
71. Aspidium Leuzeanum, Kze.; Mett. Monogr. Aspid. 116. 
An uncommon fern in Hongkong, found also on the Chinese
