HIGHLAND PLANTS FROM NEW GUINEA. - Asli 
whole cavity thus formed, beyond which they partially protrude in age. This one 
Seems unique among tree-ferns as ascending actually to frosty subalpine heights 
within the tropics. In this instance the effect of cold on the plant is shown by the 
manner, in which sometimes its fronds become curled up. 
Another Cyathea occurs among these highland-plants, but at lowe levels ; it 
is of the more usual type, with flat frond-segments and more shallow indusium. 
Polypodium punctatum ; Thimberg, Flora Japonica, 337 (1784). 
Mount Victoria. 
Polypodium trichopodum. 
Dwarf; fibrils very thin ; rhizome creeping, closely beset with pale-brown broadish 
membranous scalelets ; stalks longer than the fronds, capillary-thin, bearing scattered 
spreading rather long delicate hairlets; fronds very small, of thinly chartaceous 
texture, from elliptic-to narrow-lanceolar, undivided, somewhat copiously beset with 
very thin spreading brownish hairlets; venules concealed, free, two-branched, 
thickened at the end, and ceasing at a slight distance from the margin of the frond ; 
masses of sporangia several or some few, roundish, closely approximated near the 
median line of the frond, occasionally reduced to two only ; sporangia on conspicuous 
stalklets, many of them terminated by from one to four minute bristlets. 
Mount Victoria. 
Stalks attaining a length of four inches. Well developed fronds one to two 
inches long, one-sixth to one-third of an inch broad. Sorus-fruitmasses propor- 
tionately large. Bristlets of the sporangia somewhat antenna-or horn-like, rather 
longer than the latter. 
This unexpected characteristic of sporangia bearing hairlets may perhaps become 
‘of diagnostic value in pteridography ; the microscopic objects, thus presented, are 
remarkable and beautiful; these hairlets are accessory and superficial organs. A 
similar occurrence was noted by Bauer in Polypodium crenatum, and Presl seems to 
have observed it in several species of the section Goniopteris. Systematically this 
plant should be placed in the vicinity of P. setigerum and P. Hookerii. 
Aspidium aculeatum ; Swartz in Schrader’s Journal fuer die Botanik II, 37 (1800). 
Mount Musgrave and Mount Knutsford. 
__ There were also gathered small specimens of what may be Lomaria Capensis ; 
they are without fructification. 
Taenitis blechnoides ; Swartz, synopsis filicum 24 et 220 (1806). 
Mount Knutsford, but perhaps not in the highest regions. It was mentioned 
as indigenous to New Guinea before ; see “ Papuan plants,” II, 22.
