I have found it impossible to separate this plant from the Kinabulu 
species, which at first glance looks distinct, because of the white villous indu- 
mentum densely covering the young shoots. The leaves of the Arfak plant 
are quite glabrous on both sides, but no young shoots are present on the 
specimens. The yellow flowers, 1-16 in the axils of the leaves, are identical 
in size and structure, even to the small number of ovules, 10-12 in each 
loculus ; in both plants the calyx and pedicels are villous. On skeletonising 
the leaves no radical difference was apparent in the arrangement of the 
veins. 
Many of the Kinabulu high altitude plants from 7000-10,000' are 
characterized by hairy covering, due to the exposed conditions and cold 
nature of the soil. None of the Arfak plants, on the contrary, show this 
peculiarity, being less exposed to wind and sudden changes of temperature, 
and growing on well-drained granite gravel soil. 
Myrtus flarida is noted by Stapf as the first Myrtle described for 
Malaya, and it still maintains interest as being, so far, the only species 
common to both N. Borneo and New Guinea; but Ridley has since 
described three from Mt. Carstensz, in Dutch S.W. New Guinea, at still 
h gher altitudes, while Hugenia scolopacina Ridl. from the same locality 
is undoubtedly a Myrtus, very near the present species, and three more 
are included here.

Fl., Fee. Dee. 5601. ; 
A densely spreading shrub with small leaves suffused with red, very 
closely arranged up the stem, which is cylindrical, clothed with a reddish 
papery cortex, very glandular on the young wood. Leaves + 1 em. by 
8 mm., with midrib slightly impressed on the upper surface and indistinct 
on the lower; petioles 4 mm. long, glandular. Peduncles sparsely villous 
when young, 2-3 mm. long. Flowers subtended by two villous, narrow- 
linear bracts 3mm. long. Calyx-lobes villous when young, 2 mm. long, 
narrowing from a broad base. Petals glandular, 4mm. by 1 mm. Stamens 
as long as or just exceeding the petals; anthers globose. Style thick,
