70 cm longa, rhachi doorsum setis minoribus sparsius vestita; pinnulis 
utro(]uo latere ca. 30, brevistipitatis, basi more A. evectae inaequalibus,

'An enormous fern. The peculiarly hairy stipe and rachis give it a most 
bizarre appearance." These parts arc unknown on a large part of the species of 
AnyiopfeHs; but tliis one has good distinguishing characters in the single pin- 
nules. These are in form like those of typical A. evecta (as represented by r>e- 
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 lias 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 50-00 cm alta, ^0-25 cm lata, pinnata; 
pedicellis pinnanim 1 em longis, ad rbucbin articulatis; pinnis usque ad 
15 cm longis, 25-30 mm latis, basi euneatis, valde acuminatis, integris

fugace. 
Sarawak, Bungo Range, Brooks 8, April, 1909. 
DifTerent 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 C. moJuccanu, 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 inenne, atropurpureo, 50 em alto; fronde 
glabra, bipinnata; pinnis stipitatis 35 cm longis, pinnulis stipitatis, 
aeutis, frondis sterilis usque ad 6 cm iongis, 16 mm latis, infiniis pro- 
funde, alns levius incisis, lobis crenatis, falcato-rotundatis, subcoria- 
ceis, fei-tihs, usque ad 4 cm longis et 6 mm latis, lobis triangularibus, 
sons multis, parvis, costularibus vel more C. glabrae deorsnm divaricatis. 
Sarawak, Bongo mountain, Brooks and Hewitt 21. 
A most distinct species, although its affinities are clear. 
Cyathea recommutata Copel. 
Sarawak, Penrisaen mountain, alt. 1,100 m, C. J. Brooks GO 
The species is founded on Cuming S06, from Malacca, and is reported from 
Batjan by Christ. *
