PAPUAN FERNS. 69 
CYATHEACEAE. 
DICKSON I A rVHeritier. 
1. D. papuana F. v. M., det. by Maiden. 
No. 230, Ambasi ; No. 350, Lakekamu. 
This fern is reduced by all recent authors to Saccoloma sorhifolium (Sm.) 
Christ, I doubt the identity of these two; but be that as it may, the fern 
is a DicJcsonia rather than a Saccoloma. If one does not like to call it Dichsonia, 
it is probably Cystodium J. Sm. The mass of scales on and about the bases of 
the stipes is altogether Dicksonia-like. I have examined numerous sporangia 
from both of King's collections and find that a majority have a somewhat 
oblique annulus interrupted by the pedicel. A smaller number have the annulus 
uninterrupted. The stomium is like that of other Dicksoniae.

CYATHEA Smith. 
1. .C. fusca Baker. 
Nos. 181, 246, 277, 
New Guinea. 
The veins and costae are not glabrous. I know this fern only by description. 
2. C. contaminans (Wall.) Copel. 
No. 215i in open coimtry. 
Malaya, India. 
Nos. 227 and S56 are other species of which the specimens are insufficient for 
certain identification. No. 227 is very probably Tindescribed. 
HYMENOPHYLLACEAE. 
HYMENOPHYLLUM Smith. 
r 
1. H. ooides F. iluell. & Bak. (?) 
No. 106, Goodcnough Bay. 
New Guinea. 
This fern is so determined by F. Manson Bailey, and I presume that he is 
acquainted with the original plant. In that case the original description is 
pecnliar in several vespect-s especially in calling the pinnae lanceolate; those 
of this plant are rather elliptic. 
No. 2/t6 is another very slender plant more than 30 cm high and less than 
3 cm wide; it agrees better than No. 106 with the description of H. ooides. It 
is a relative of H. hlumeaniim Spr. 
2. H. dilatatum (Forst.) Sw. 
No. 186, Gootlenough Bay. 
Malava to New Zealand. 
Identification not positive as the specimens are sterile. 
3. H, Reinwardtii v. d. Bosch. 
No. 210, Goodenough Bay, altitude 1,200 m. 
Java, Sumatra. ^ 
Smaller and much more crisped that the form figured by van den Bosch, but 
otherwise not different.
