BORNEAN FERNS.

The pinnae of Brooks’ specimen are exactly like Cuming’s; but Brooks’ 
specimen includes also the base of the rachis,. which bears leaflets the pinnules of 
which are deciduous, leaving sharp spines, in one instance branched. I suspect 
that this is also Alsophila ramispina Hooker. 
Cyathea paraphysata Copel. spec. nova. Plate XV. 
Stipite ad basin supra paleis fuscis lanceolatis, integris, usque-ad 16 mm 
longis, acutisl et aliis minoribus vestito, sursum nudo, fere inerme, fusco, 
sicco 8 mm crasso, 40 cm alto; rliachi supra minute velutina; pinnis 
medialibus maximis, 40 cm longis, brevi-stipitatis, acuminatis, rhachi 
supra ut frondis, infra minute puberula ; pinnulis sessilibus, obtusis, 6-7 
cm longis, 14 mm latis, ultra mediam laminam pinnatifidis, costa supra 
velutina, infra basin versus minute squamulacea; lobis integris, obtusis, 
falcatis, 3 mm latis, subcoriaceis, lamina glabra, infra pallida, costula 
inf ra, paleis paucis minutis bullatis pallidis vestita; venis simplicibus 
utroque latere 4 vel -5 ; soris medialibus, exindusiatis, paraphysibus spo- 
rangia multo superantibus, trichoideis, haud clavatis. 
Sarawak, Penrissen mountain, alt. 150 m, Broolcs 57. . 
Near to G. squamulata (Bl.) but having long paraphyses, and to C. obscura 
(Scort.) but the basal scales entire; and differing from both in the mostly blunt 
pinnules. 
Cyathea (A)sophila) Brooksii Copel. spec. nova. Plate XVI. 
Trunco 1 m alto; stipite ca, '45 cm alto, purpureo-nigro, praecipue 
basin versus paleis stramineis minute nigro-ciliatis anguste lanceolatis 
aciculatis duris dense vestito; fronde ca. 75 cm alta, vix 60 cm lata, 
ovata, rhachi deorsum ut stipite, sursum pallida supra velutina infra 
glabrescente ; pinnis medialibus maximis, 30 cm longis, 10 cm latis, 
subsessilibus, acuminatis, rhachi anguste alata; pinnulis subsessilibus, 
proximis, basi trunca.tis, obtusis, 15 mm latis, vix ad mediam laminam 
incisis; lobis proximis, valde falcatis, late oblongis, integris, papyraceis, 
lamina glabra; costa supra sparse pilosa infra fere glabra; costulis infra 
squamulis bullatis minutis deciduis albis ornatis; venis utroque latere 
4-6, plerisque simplicibus; soris medialibus, exindusiatis, paraphysibus 
multis, trichoideis, haud clavatis nec multo ultra sporangia protensis. 
Sarawak, Penrissen mountain, from 900 m to the summit, common, Brooks 59. 
A relative of G. obscura (Scort.) from which it is sharply distinguished by 
the falcate lobes. The point of the lobe usually receives the uppermost acroscopic 
vein, instead of the apex of the costule; the two forks of a veinlet sometimes 
unite again. 
This is distinguished from the group of C. glabra by the numerous pale scales 
on the stipe. 
Cyathea borneensis Copel. spec. nova. 
Stipite fusco, nitido, spinoso, ad basin paleis rigidis nitidis atro-fuscis
