28. Dwarfed Intermediate Mossy Forest. 
A lateral spur from the 8.W. ridge to the lake bounding the southern 
part of the marsh to the north, bore rather a spaced xerophytic type of small 
forest, on the edge of which the undergrowth between the small trees and 
shrubs was very thick; here the ferns *Dryostachyum splendens and the delicate 
“Pesia radula, only known from Sumatra, °Selaginella angustiramea, with 
deltoid fronds up to *50 m., and °Phaius Javus var. papuanus were collected. 
Of the small stunted trees about 3 m. high, those in flower were Pipturus 
papuanus, Gibbsia insignis, *Glochidion Merrillti, only known from the 
Philippines, Homalanthus arfakiensis, * Dodonea viscosa, Acronychia papuana, 
and the very abundant °Medinilla Forbesii, with white and pink flowers 
in cauline fascicles up the bare grey nodose stems, °“Luzuriaga aspericaulis 
twining, the moss ° Taxithelium substigmosum, *Humata pusilla, *Polypodium 
Jasciatum, °P. scabristipes, and Glomera similis, the latter with small white 
flowers, were epiphytic on the trunks and upper branches of the small trees.

I did not work over the Alfuero “ kebuns,” which were dotted with a 
Pandanus sp., * Dodonea viscosa, clumps of *Rubus glomeratus and *R. rose- 
folius, also masses of the handsome cream-tlowered *Riedelia lanata, about 
3m. high, Wedelia biflora and Hydrocotyle javanica, the latter spreading on 
the ground, 
2a. Intermediate Mossy Forest, 7000-7500'. 
Crossing a stream we entered a dry type of intermediate mossy forest 
with trees of about 13 m., where, as undergrowth, *Asplenium scandens, a 
green orchid Microstylis grandiflorus, small erect plants of Symbegonia parvi- 
folia, with red foliage and pink flowers, and Riedelia exalata, with yellow 
and red flowers, about 1 m. high, were collected. The typical coniferous 
seedlings of the region abounded as usual, with the undershrubs Sheflera 
arfakensis and the white Medinilla arfakensis, the epiphytic °D, agatho- 
demonis, D. curvimentum, and ° Bulbophyllum pristis. 
With increase in altitude the forest becomes smaller, though still dry in 
type, the trees being less erect and more branched in habit, 
2B. Dwarfed Intermediate Mossy Forest, 7500-8500". 
Trichomanes pallidum, Dryopteris villosipes, * Lindsaya rigida, °Davallia 
Schlechteri, °Polypodium argyropus, *P. serratodentatum, * Vittaria crassi- 
folia, *Psilotum flaccidum, Piper pilosulinodum, and Henslowia crassifolia 
with minute fleshy-green leaves and twining ends to the branches, were 
collected as epiphytes. In an open Space a group of young trees of Liby- 
cedrus arfakensis, about 30 m. in height, with graceful branches sweeping
