Angiopteris ferox Copel. spec. nova. Plate XII. B. 
Stipite rhachique setis 10-15 mm longis atrofuscis duris obsitis; pinna 
70 cm longa, rhachi deorsum setis minoribns sparsius vestita; pinnulis 
ntroqne latere ca. 30' brevistipitatis, basi more A. evectae inaequalibus, 
infimis diminutis, medialibns 16 cm longis, 2 cm latis, apice acuminato 
leviter serrato, aliter nbiqne minute dentatis, coriaceis, costa utrinque 
prominente, nigra, infra praecipue deorsum squamulifera ; venis con- 
spicuis, pellucidis ; venulis recurrentibus opacis, fere ad costam protensis ; 
soris plerumque contiguis, ca. 0.7 mm a margine remotis, sporangiis 7-9.

“An enormous fern. The peculiarly hairy stipe and rachis give it a most 
bizarre appearance.” These parts are unknown on a large part of the species of 
Angiopteris ; but this one has good distinguishing characters in the single pin- 
nules. These are in form like those of typical A. evecta (as represented by De- 
Vriese) ; but the sori are much closer to the margin; the latter is rather sharply 
toothed to the base; the false veins are opaque, and the constriction below the 
apex of the pinnule is less abrupt. A. similis has the venation almost invisible 
by reflected light. 
Cyathea arthropoda Copel. spec. nova. Plate XIII. 
Stipite ad basin paleis stramineis 5-8 mm longis vestito, aliter glabro, 
inerme, fere 40 cm alto; fronde 50-60 cm alta, 20-25 cm lata, pinnata; 
pedicellis pinnarum 1 cm longis, ad rhachiri articulatis ; pinnis usque ad 
15 cm longis, 25-30 mm latis, basi cuneatis, valde acuminatis, integris 
vel leviter crenatis, papyraceis, glabris; soris 1-3-seriatis, parvis; indusio 
fugace. 
Sarawak, Bungo Bange, Brooks 8, April, 1909. 
Different from C. moluccana in the relatively short and broad deciduous pinnae 
narrowed to the base, and long pedicels. 
Mr. Brooks has also sent me a very large form of G. moluccana, collected at 
Bidi in August, 1907. 
Cyathea Hewittii Copel. spec. nova. Plate XIV. 
C. gregis C. glabrae (Blume) frondibus dimorphis ; stipite ad basin 
paleis fuscis integris 8 mm longis vestito et foliolis in spinis reductis 
armato, aliter glabro, fere inerme, atropurpureo, 50 cm alto; fronde 
glabra, bipinnata; pinnis stipitatis 35 cm longis, pinnulis stipitatis, 
acutis, frondis sterilis usque ad 6 cm longis, 16 mm latis, infimis pro- 
funde, aliis levius incisis, lobis crenatis, falcato-rotundatis, subcoria- 
ceis, fertilis, usque ad 4 cm longis et 6 mm latis, lobis triangularibus, 
soris multis, parvis, costularibus vel more C. glabrae deorsum divaricatis. 
Sarawak, Bongo mountain. Brooks and Hewitt 21. 
A most distinct species, although its affinities are clear. 
Cyathea recommutata Copel. 
Sarawak, Penrissen mountain, alt. 1,100 m, G. J. Brooks 60. 
The species is founded on Cuming 396, from Malacca, and is reported from 
Batjan by Christ.
