dibiilifomiibus, tnnuatis, limbo paullo dilatato vel interdum recto, recep- 
taculo exserto. 
No. 150. 
Differs evidently from T. javanicum Bl., T. atrovirens Kze., and T, ZoUingen 
V. d. B. in the coarse veins, which stand at a much more acute angle to tlie 
costa. The frond is also conspicuously more compact and the pinnae more 
rounded. 
9. T. (Cephalomahes) 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 eimeatis, 
apice rotundatis, dontatis et interdum partitis, venatione sublaxa; pinnis 
supremis fertilibus, l-^-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, Lakelvamu. 
The racemose or narrowly paniculate sori make this very distinct from any 
species hitherto known. 
10. T. (Cephalomanes) Kingii Copel. spec. nova. 
Ehachi anguste alata, glabra; pinnis laceratis; paniculo breve; indusio 
conico, vix 2 mm alto, 1 mm vel ultra lato, limbo baud dilatato; alitor 
praecedenti simile.

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. humrle Forst. 
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 mos part natural and easily recognized. As there are st,ch p rfec seri

hold the=e as distmct genera, and as I do not regard them as natural in detail 
that rs, as absolutely homophyletic, I am not concerned as to the gene ic val di J 
of the names chosen for these groups. They are: me ^aiiait}
