leaves, and smothered in golden-orange flowers. A Psyclwtria sp., resembling 

 P. sarmentosa, with white panicles of flowers, Idenburyia arfakensis repre- 

 senting a new natural order, Myrtus flavida var. glabrescens, a glabrous form 

 of the Kinabalu specie?, Jambosa arfakensis, with small thick leaves and 

 white flowers, Palmervandenbroefcia papuana, an interesting new genus in 

 Araliacese, and Timonius filipes, were in full flower. 



3. Mossy Forest. 



The occurrence of this sterile type of mossy forest, as distinct from the 

 intermediate form, was limited to the highest points of the ridge, where 

 the prostrate and erect trunks of the small stunted trees with the ground 

 between were swathed in long moss, which, as usual in this type of associa- 

 tion, stands out straight from its supports, rigidly turgid and generally in 

 vegetative condition. 



*Schizcea malaccana, *Gahnia psittacorum, 1 m. high, Halorrhagis suf- 

 fruticosa, Nepenthes maxima v<ir. nana. the twining L/'uzuriaga aspericaulis, 

 .Rhododendron angiense, an undershrub, with * Trichomanes digitatum, 

 Hymenopliyllum cincinnatum, Poly podium papuanum, and P. remigerum 

 as epiphytes, were collected. 



b. LAKE BASIN. 

 2 a. Intermediate Mossy Forest. 



An isolated circular forest patch, in about the centre of the marsh, proved 

 the best collecting-ground in the mountain-forest area. 



The average height of the trees was about 16 m. a few symmetrical conical 

 dark green crowns of Libocedrus arfakensis^ the topmost branches of which 

 were all dead, as if the trees had reached the limit of their development or 

 the roots had penetrated into an unfavourable substratum, with the smaller 

 .feathery glaucous green of Podocarpus papuanus rising above them. 



On the exterior a fringe of bracken bordered this patch on the north, 

 while towards the south a wild dense upgrowth of grass-jungle, fern, and 

 shrubs seemed to point to the forest spreading in that direction. On the 

 western or lake side, a raised spit of coarse granite-sand, carrying a 

 graduated growth of Bceckea fmitescens, intruded into the marsh, the level, 

 no doubt, marking that of the forest-patch. 



Trees. On the southern edge, where the trees were, more advanced, 

 *Podocarpus Rumphii and P. papuanus in full fruit, * Pliyllocladus hypo- 

 phyllus, Trimenia arfakensis with white flowers, the scented Pullea papuana, 

 Spirceanthemum bullatum, both with plumose white racemes, the latter showing 

 peculiarly bullate leaves, Acronychia papuana, * DodoncBa viscosa, * Bceckea 

 frutescens ) the delicate Metrosideros arfakensis, with small glistening leaves
