138 DR. H. F. HANCE'S SUPPLEMENT TO 
Mettenius, which, as first set forth in his ‘ Filices horti Lipsiensis’ 
and subsequently amended in various other publications, seem to 
me, with some slight modifications (such, e. g., as the reduction 
_of Phegopteris to Aspidium, and the separation of Athyrium from 
Asplenium), to be by far the most philosophical and carefully con- 
sidered of any yet propounded—the larger genera (so much broken 
up by Fée, J. Smith, Moore, and others) being preserved, and all 
based on definite characters employed uniformly throughout the 
whole classification—a plan which ensures, as far as practicable, 
the equality in rank or value of the genera. 
61. Trichomanes latemarginale, Eaton; Hook. and Bak. Syn. 
Fil. 79. 
Diseovered by the late Dr. Harland and myself, in July 
1854, growing along with Utricularia Harlandi, Oliv., on the per- 
pendieular wall-like sides of a narrow ravine near Causeway Bay. 
Not known from elsewhere. 
*Chrysodium vulgare, Fée, Hist. Acrostich. 97. (=Acrostichum au- 
reum, Linn.; Benth. Fl. Hongk. 443.) 
*Chrysodium Harlandi, mihi. (=Acrostichum decurrens, Benth. Fl. 
Hongk. 443; but not of Desvaux.—A. Harlandi, Hook. Sp. Fil. v. 
274.) 
*Chrysodium repandum, mihi. (=Acrostichum repandum, Blume; 
Benth. Fl. Hongk. 444.) 
62, Polybotrya marginata, Blume; Presl, Tent. Pteridogr. 231 ; Fée, 
Hist. Acrostich. 75. (=Acrostichum (Egenolfia) appendiculatum, 
Willd.; Hook. Sp. Fil. v. 251.) 
In shaded ravines, but not very common. Occurs throughout 
the entire Indian continent, in Ceylon, the Malayan and Philip- 
pine islands, and Cochinchina. The late Prof. Mettenius (Fil. 
Hort. Lips. 24) was disposed to refer this to Lomariopsis ; but he 
included some of the forms belonging to it in Polybotrya. 
*Tenitis microphylla, Mett. msc. in Kuhn, Fil. Afr. 58. (=Drymo- 
glossum carnosum, Hook. part. ; Benth. Fl. Hongk. 444.) 
Mr. Baker remarks (Syn. Fil. 397) that this differs from T. car- 
nosa by the sporangia being mixed with hairs instead of peltate 
scales; but this is not the case in any Japanese or South-Chi- 
nese specimens I have examined. It is obviously impossible to 
retain Drymoglossum as a genus. 
*Lindsaya tenuifolia, Mett. in Ann. Sc. Nat. Par. ser. 4, xv. 64. (= 
Davallia tenuifolia, Sw. ; Benth. Fl. Hongk. 462.)
