COPELAND. 
dibuliformibus, truncatis, limbo paullo dilatato vel interdum recto, recep- 
taculo exserto. 
No. 150. 
Differs evidently from T. javanicum Bl., T. atrovirens Kze., and T. Zollingeri 
v. d. B. in the coarse veins, which stand at a much more acute angle to the 
costa. The frond is also conspicuously more compact and the pinnae more 
rounded. 
9. T. (Cephalomanes) acrosorum Copel. spec. nova. 
Stipitibus confertissimis, 1-2 cm altis; fronde 6-10 cm alta, 1.5-2 
cm lata, rhachi pilosa glabrescente ; pinnis 10-12 mm longis, basi cuneatis, 
apice rotundatis, dentatis et interdum partitis, venatione sublaxa; pinnis 
supremis fertilibns, 1-3-soratis, lamina carentibus, indusio 2.5-3 mm 
longo, infra limbum plus minus dilatatum vix 1 mm crasso; receptaculo 
usque ad 7 mm exserto. 
No. 352, Lakekamu. 
The racemose or narrowly paniculate sori make this very distinct from any 
species hitherto known. 
10. T. (Cephalomanes) Kingii Copel. spec. nova. 
Rhachi anguste alata, glabra; pinnis laceratis; paniculo breve; indusio 
conico, vix 2 mm alto, 1 mm vel ultra lato, limbo haud dilatato; aliter 
praecedenti simile. 
No. (?) Lakekamu. 
I have only one frond of this plant, but it has such a combination of dis- 
tinctive characters that I do not believe it can vary into T. acrosorum. 
11. T. humile Porst. 
No. 136, on the coast. 
New Zealand to Formosa. 
No. 3^0 is a related species, but the specimen is sterile.

The great body of the species of this genus fall into three groups, which are 
for the most part natural and easily recognized. As there are such perfect series 
of intermediates that the majority of my contemporaries have no disposition to 
hold these as distinct genera, and as I do not regard them as natural in detail, 
that is, as absolutely homophyletic, I am not concerned as to the generic validity 
of the names chosen for these groups. They are : 
§ 1. Lastraea. Fronds decompound or veinlets forked. This is in my opinion 
the most primitive group. From it have been derived Tectaria and Polystichum, 
which in turn have their daughter-genera. 
§ 2. Thelypteris. Fronds as a rule deeply bipinnatifid with simple veinlets, 
having the aspect of the next section, but the veins free. 
§ 3. Nephrodium. Pinnae not so deeply cut as to prevent anastomosis of at 
least the basal veinlets.
