1. T. ferruginea (Mett.) Copel. comb. nova. 
Phegopteris ferrtiginea Mett. Ann. Mus. Lugd.-Bat. 1 (1864) 224. 
No. 26/,. 
New Guinea.

I have sometime since published the opinion that Tectaria is derived from a 
Dryopteris of the group of D. dissecta; this species is so near that group that 
at first sight I did not suspect its being a Tectaria. It impresses me as easily 
the most primitive known representative of its genus. 
2. T. mafayensis (Christ) Copel. 
No. 359, Lakekamu. 
Western Malaya and the Philippines.

3. T. cesatiana (C. Chr.) Copel. comb. nova. ^^ 
Aspidium cesatianum C. Chr. Index (1905) 68. 
No. 161 J Ambasi; No. 3/f8, Lakekamu. 
New Guinea. 
iginally described by Baker, as Aspidium heccarianum; this specific name is 
not transferred because of the earlier Poh/podium heccarianum Cesati, which 
must also be Tectaria. 
4. T. Menyanthidis (Presl) Copel. 
Nos. 169, 180, Ambasi. 
r 
New Guinea, Philippines, Solomon Ids. 
Distinguished from T. crenata by. the somewhat scattered sori. 
5. T. decurrens (Presl) Copel. 
No. 251, Ambasi. 
Polynesia to India and China. 
6. T. papuana Copel. spec. nova. 
Stii^ite ca. 45 cm alto, nigro, iiitido; fronde deltoidea, pinnata, ca. 
40 cm alta, 30 cm lata; pinnis infimis stipitatis, deltoideis, cordatis, 
subfalcatis, acutis; seqnentibus utroqiie latere 1, rotundato-adnatis, late 
laneeolatis, 4 em latis, 15 em longis, subfaleatis; pinna apicale tripartita, 
segmento mediale ea. 20 cm longo, 5 cm lato; pinnis subsinuatis, coriaceis, 
supra nisi ad costas glabris, infra minute puberulis olivaceis; venis ad 
marginem attingentibus, retieulatione venularum minuta; soris grand- 
ibuB, praecipue inter venas biseriatis, supra conspicuis, indusiis peltati^, 
glandiilosis, persistentibus. 
No. 100. 
Near T. tripartita (Baker ut Nephndium) but not identical unless the 
diagnosis of that species is particularly poor. I have a New Caledonia fern 
determined as Aspidium tripartitum which differs from T. papuana only in beinc. 
thinner and more ample; the two are easily conspecific. But neither has the 
indusia sagenioid or glabious, and there are minor diiferences.
