PAPUAN FERNS. 
71 
This was included with some other species in T. anceps Hooker. T. millefolium 
Presl was based on another plant, also included in Cuming 162, which is T. 
maximum Bl. This is more like T. rigidum Swtz. which however is a much 
smaller plant, less divided, with shorter indusium, and is very doubtfully present 
in the Orient. 
The Papuan specimen has much broader pinnae than those of the Philippines; 
I have not made it a type because I have not the rhizome. 
3. T. aphlebioides Christ. 
No. 193. 
New Guinea. 
No. 68 of Karnbach’s collection, from “Nuselang u. d. Sattelberges Weg nach 
Schleo,” distributed as T. bauerianum, is also this species. T. bauerianum, judg- 
ing by our Norfolk Island specimens, is altogether distinct, both from this fern 
and from T. apiifolium Presl. 
4. T. dentatum v. d. B. ( ?) 
No. 353, Lakekamu. 
Polynesia. 
I doubt the identity of this specimen with the species named, but it is very 
near it. 
6. T. latipinnum Copel. spec. nova. 
Rhizomate repente, 25 mm crasso, pilis purpureo-nigris aeicularibus 
dense vestito; stipite 15-20 cm alto, rhachique atropnrpureis, decidue 
pilosis deinde hispidis; fronde trigona, 15 cm alta, 10 cm lata, quadri- 
pinnatifida; pinnis et pimrulis deltoideo-lanceolatis, pinnnlis primariis et 
secundariis acroscopicis maximis; pinnnlis 11 incisis, segmentis nltimis 
0.1-0. 2 mm latis, 0.5-1 mm longis, acutis, glabris, coriaceis; soris para- 
tactis, indnsiis 1 mm longis, 0.6 mm latis, infra medium alatis, truncatis, 
receptaculo paullo extruso. 
No. 108, Waria River, German New Guinea, altitude 900 m. 
Easily distinguished from the preceding, and from T. rigidum in all forms 
known to me, by the very broad pinnae and pinnules. 
6. T. cupressoides Desv. 
No. 107, Waria River, German New Guinea, altitude 900 m. 
Westward to Madagascar. 
This agrees fairly well with van den Bosch’s plate of T. obscurum Bl., but 
all our Javan specimens supposed to be this species have bilabiate indusia. 
7. T. pallidum Bl. 
No. 18$, Goodenough Bay. 
India to Polynesia. 
8. T. densinervium Copel. spec. nova. 
Cephalomanes stipite valido vix 10 cm alto, fronde 18 cm alta, vix 
4 cm lata, sursum sensim angustata, pinnis proximis valde imbricatis, 
infhnis haud remotis, obliquis, apice rotundatis, ciliatis, venis angulo acuto 
orientibus, proximis, crassis, furcatis et inferioribus acroscopicis iterum 
furcatis ; soris partem superiorem frondis occupantibus, acroscopicis, ad 
pinnam quamquam usque ad 8, uniformibus, indusiis compresso-infun-
