paucidentatis, 2-8 mm. longis, 0°5 em. latis. Sori solitarii in lobis brevibus pin- 
narum terminales. Jndusiwm ad medium divisum, valvis obtusis truncatisve integris,

Hab. Arfak Mts.,8.W. ridge, Angi lakes, 8500’, epiphytic in moss-grown 
forest. Dec. 5989. 
This species has sori much as in H. cernuum (No. 5964), but is not one- 
quarter the size, and is not cristate on the costules of the segments. It 
approaches /7. holochilum Van den Bosch (Hymen. Javan. t. 34), but has a 
stouter, more hairy rhizome and stipes (the latter winged throughout its 
length), and much narrower ultimate segments. The dried plants are very 
convolute. 
CYATHEA ARFAKENSIS Gepp, sp. nov. 
Stipes circ. 18 cm. longus muricatus inferne fuscus superne griseo-purpurascens ; 
rhachis purpurea haud nitens supra ferrugineo-pubescens glande juxta cujusque pinne 
basin instructa. -Frons lineari-lanceolata, circa 80 em. longa, 13 em. lata, bipinnata ; 
pinne alterne 35-jugatie stipitate lanceolate, 8 em. long, 2 cm. late, obtuse, 
pinnulis 15-20-jugatis, stipitatis 1 cm. longis, 0-4 em. latis, imbricatis oblongis 
obtusis, inferioribus paucipinnatis (segmentis rotundatis), superioribus lobatis vel 
crenatis vel integris (versus apicem); rhachibus pinnarum supra pubescentibus, infra 
squamulis albidis sparse instructis. Sori costales 4—5-jugati; venule pinnularum 
5-6 parum conspicue simplices furcateve. Textura coriacea; frons supra griseo- 
purpurea, infra pallide brunnea. Indusiwm persistens hemisphericum. 
Hab. Arfak Mts., S.W. ridge, Angi lakes, 8000’, undergrowth in moss- 
grown forest. Dec. 6008. ‘‘ Tree-fern.” 
The pinnz are not contiguous, but are attached to the rhachis at intervals 
of about 3cm. In the dried specimen the shortly-stalked opposite rows of 
pinnule are appressed to one another and directed upwards (apically), 
displaying the sori and concealing the upper surface.
