gradually increasing in length till at the apex they are 3 mm. by °5 mm., of 
which the apical bract only is fertile ; the mature strobilus, with swollen 
bract-bases, is 7 mm. by 4 mm., not including the seed. Ovuliferous scale 
is +2 mm. in height and 2 mm. broad, persisting in the axil of the fertile 
bract after the seed is shed. Seed 5 by 2mm. All measurements of the 
fruiting-stages and drawings are from material in formalin. Pollination 
drops were seen on the young ovules. 
The mature fruiting-form of this species was only seen in one or two 
isolated examples on the open summit of Koebré ridge, small trees +10 m. 
high, with short trunks and rounded crowns of rigid ascending branches, 
bearing numerous small red and fleshy cones. In younger stages this plant 
was very abundant on the crest of the S.W. ridge and in the forest round 
the ? lake. The foliage of the seedlings is plumose in character to 4°50 m. 
in height, when the small adpressed scaly leaves begin to appear. 
In the peculiar habit and the strap-shaped laminz of the bracts composing 
the strobilus, this species is quite distinct from known members of the genus.

A fine tree, +30 m. in height, very like P. imbricatus Bl. in habit and in 
the dimorphic foliage, both seedling and youth form of foliage being identical 
in both species—in fact, like Beccari, I took the young plant for that species 
in the field, but the foliage of the mature tree is more spreading and distinct, 
the scales of the g cones differ in shape, while the ? cones are larger and 
very glaucous in appearance. The fusion of the lamina of the fertile bract 
with the ovuliferous scale is also less complete than is the case in P. imbri- 
catus and the position of the seed is more oblique. Dr. Beccari most kindly 
sent me some of his Arfak material, published as P. imbricatus, which, on 
comparison, proved identical with the above. 
The description. of this plant being limited to the mature foliage 
and one g cone, I append what is necessarily wanting in the original 
diagnosis :-—
