VITTARIA J. E. Smith. 
1. Vittaria scabricoma Copel. spec. nova. 
Taeniopsis, paleis rhizomatis vix 5 mm longis, angustissimis, basi 
dilatatis, rigidis, sparse dentieulatis, nigris ; frondibus approximate, sessi- 
libus, 20-25 cm longis, 4 mm latis, utrinque angustatis, acuminatis, 
glabris, coriaceis ; costa manifesta baud prominente ; soris submarginalibus, 
sporangiastris claviformibus, obscuris; sporis reniformibus. 
No. 166. 
A species of the V. lineata group, which as commonly construed contains a 
number of distinct Malayan species, none of which probably belong to it as a 
species. The paleae are very harsh, having exceptionally thick cell-walls. 
2. V. scolopendri na (Bory) Thwaites. 
No. 244, Ambasi. 
Samoa to Africa. 
3. V. zosterifolia Willd. 
Nos. 199, 200, Goodenough Bay, altitude 1,200 m. 
Polynesia to the Comores. 
No. 129 is exceptionally broad and long stalked, and may be distinct. 
4. V. elongata Swtz. 
No. 187, Goodenough Bay. 
India to Polynesia. 
ANTROPHYUM Kaulfuss. 
1. A. reticulatum (Forst.) Kaulf. 
No. 316, Ambasi, a decidedly long-stipitate form. 
Polynesia to Madagascar. 
2. A. plantagineum (Cav.) Kaulf. 
Nos. 198, 234, Ambasi. 
Polynesia to India. 
3. A. semicostatum Bl. 
No. 330, Lakekamu. 
Polynesia to Ceylon. 
LOXOGRAMME (Blume) Presl. 
1. Loxogramme paltonioides Copel. spec. nova. 
Species L. lanceolatae Presl similis et affinis, soro composito utroque 
latere uno intramarginale costae parallelo, ad partem superiorem frondis 
paullum angustatam restricto. 
No. 253; No. 217 is probably a juvenile form of the same; the sori are not 
quite continuous, and in one place overlap slightly. The question raises itself, 
if Paltonium chinense (Christ) C. Chr. may not be a Loxogramme. 
2. L. involuta (Don) Presl. 
No. 297, Ambasi. 
Melanesia to Malaya and China. 
A very large form, but otherwise typical.
