Distrib. New Guinea (D.N.W., Arfak Mts., Gijellerup). 
A common and very pretty twiner with white flowers. The fruit, which 
was not available in Dr. Gjellerap’s specimens, is a roundish berry, 8mm. long 
by 6 mm. broad, 1-2-seeded, with persistent style and remains of perianth- 
tube at the base.

marginate vel glabre. Flores in spatha 2-3, sessiles; tubus gracillimus, vix exsertus; 
lobi exteriores obovati, patentes, in carina dorsali ad apicem dense barbati, interiores

lobi stigmatici lineari-oblongi, papillosi. 
Hab, Arfak Mts., Koebré ridge, plentiful on open burnt summit, 9000’. 
Fl., Fr. Dec. 5600. 
A small rigid plant, with gleaming white or pale mauve flowers, + 1-3-5 dm. 
in height. Leaves from 1:2-3°5 dm. by 5-6 mm., characterized by a line of 
matted branched hairs, containing brown colouring-matter, up the dorsal 
keel, and from the vagina to the apex on the adaxial margin of the leaf. 
Sheathing scales at the base of the leaves from 3°5 cm. long, lanceolate acute, 
brown, the old bases persisting round the stem. Svape 7°3 cm. long, more 
or less exserted from the sheathing leaves, which it exceeds or equals, or it 
may be shorter. Spathes 3°8cm. by 5mm. Perigonium tube 2 em. long, 
lobes 8 mm. long, including apical tuft of hairs 1mm. long. Anthers 3mm. 
Stigma-lobes 2 mm. 
This species is near P. Lowii Stapf. It differs in the somewhat broader 
leaves with marginal line of brown hairs and the generally white corollas 
with an apical tuft of hairs to each lobe. The transverse section of the leaf 
shows many more fibro-vascular strands and is more attenuated at the margin 
than in the above species. There is also no trace of an inner perianth, as 
Stapf also found for the Kinabalu plant. The marginal line of matted 
branched hairs is cominon to some Australian species, viz. P. sericea R. Br, 
and P. pygmea Lindl., but in every case apparently the hairs are hyaline 
and much finer in texture. ne : 
This genus, for many years supposed to be endemic in Australia, now 
includes three Malayan mountain types, viz. P. borneensis Stapf and P. Lowii 
from Mt. Kinabalu in N. Borneo, the latter also common to Mt. Halcon in 
the Philippines, and the above.
