A. Hurronu, Mitt. 
Caulis procumbens, ramis ascendentibus subpinnatim divisus ; folia cau- 
lina patentia, ovata, acumine lato apice acutiusculo, nervo indistincto 
supra medium evanido, ramea subcompressa, basi subovata, ligulata, 
acutiuscula, omnia inferne canaliculato-concava, apicem versus plana, 
cellulis rotundis obscuris papillosis areolata, margineque crenulata. 
Hab. New Zealand, Great Barrier Island, ZZutton et Kirk. 
Similar to A. tristis, Cesati, in stature, but more depressed and 
forming matted tufts. 
A. EXILIS, Mitt. 
Caulis procumbens, ramis irregularibus subpinnatim ramosus; folia 
compressa, caulina basi ovata ligulata obtusiuscula, rameaque patentia 
conformia vel basi minus ovata magis compressa, inferne canaliculato- 
concava, apice plana obtusissima, cellulis rotundis obscuris minutis- 
sime papillosis areolata, nervo indistincto supra medium evanido. 
Hab. Africa australis, Natal, Attercliffe, J. Sanderson. 
A. Huttoni minor, foliis rameis obtusioribus magis compressis. 
CYATHOPHORUM, Brid. 
C. SUBLIMBATUM, Tw. et Mitt. 
Caules apice szepe attenuati, foliis magnitudine decrescentibus, simplices; 
folia lateralia divergentia, ovalia acuminata, margine a medio ad apicem 
usque denticulis angustis serrata, limbo obsoleto, nervo ad tertiam 
folii longitudinis partem producto simplici furcatove; foliastipuliformia 
late ovalia acuminata, enervia, margine superne denticulata. 
Hab. las. Ceylon, Dr. Thwaites. 
C. Hookeri statura adspectuque simile, foliis autem limbo indistincto 
cellulisque paululum majoribus et foliis stipuliformibus enervibus den- 
tieulatis diversum. 
HyPOPTERY.GIUM, Brid. 
Euhypopterygium, Mitt. Musc. Aust. Amer. 
H. APICULATUM, Thw. et Mitt. 
Dioicum ; folia in ramorum primariorum medio latissime oblongo-ovata, 
in acumen breve producta, nervo infra apicem evanido, limbo superne 
denticulato circumdata, cellulis parvis rotundis obscuriusculis ; folia 
stipuliformia orbiculata, nervo in acumen angustum excurrente, inte- 
gerrima; perichetialia late ovata, nervo excurrente acuminata ; theca 
in pedunculo elongato, oblonga, horizontalis, operculo longirostri. 
Hab. Ins. Ceylon, Dr. Thwaites. 
Stipes semiuncialis, in frondem circiter semiunciam longam apice divi-
