IsLAND, STEWART IsLAND: Common in mountain districts throughout. Usually 
_ between 2500 and 4000 ft., but descends to sea-level in Stewart Island. 
A very remarkable little species, probably the smallest known pine. Fruiting 
specimens can often be seen barely 3in. in diameter, although the usual size of the 
plant is much more. The minute imbricated leaves are often entirely wanting, even in 
old plants; at other times both imbricated and spreading leaves occur on the same 
branch. 
3. PHYLLOCLADUS L. C. Rich. !O76. 
Trees or shrubs; branches often whorled; branchlets flattened and 
expanded into rigid and coriaceous toothed or lobed leaf-like cladodia. 
True leaves reduced to linear scales. Flowers monoecious or dioecious. 
Males fascicled at the tips of the branchlets, catkin-like, peduncled; each 
peduncle arising from the axil of a leafy bract. Staminal column oblong 
or cylindrical; anthers numerous, densely spirally imbricate, 2-celled ; 
connective prolonged into an acute claw. Female flowers sessile on the 
margins of the cladodia or on peduncle-like divisions of the cladodia. 
Ovuliterous scales 1 or several, thick and fleshy, free. Ovule solitary, 
erect. Seeds erect, ovoid or oblong, compressed, protruding from the 
enlarged and fleshy scales, each seated within a cup-shaped aril 
Cotyledons 2. 
Besides the 3 species found in New Zealand, there is one in Tasmania, another in 
Borneo, and a sixth in New Guinea and the Philippine Islands. The genus is 
remarkable for the flattened cladodes or leaf-like branchlets, which take the place of 
the true leaves, these last being reduced to linear deciduous scales. The New Zealand 
species have been excellently described and figured by Mr. Kirk in vol. x of the 
‘Transactions of the New Zealand Institute ’’ and in his ‘‘ Forest Flora.’

1. P. trichomanoides D. Don in Lamb. Pin, ed. ii, App—A tall 
graceful tree 50-70 ft. high; trunk 1I-3ft. diam.; branches whorled, 
slender, spreading. Cladodes or flattened leaf-like branchlets alternate 
and distichous on whorled rhachises 1-3in. long, each rhachis and its 
cladodes resembling a pinnate leaf; each cladode 4-1 in. long, obliquely 
cuneate or rhomboid, thick and coriaceous, lobed or pinnatifid, the lobes 
truncate or erose; veins spreading. Leaves of seedling plants $-3 in. long, 
narrow-linear, soon deciduous; of older plants reduced to minute subulate 
scales at the base of the rhachises of the cladodes or of the cladodes 
themselves. Flowers monoecious. Males in fascicles of 5-10 at the tips 
of the branchlets, 3-}in. long. Females on the margins of modified 
cladodes at the tips of the branchlets, cladodes much reduced in size, often 
little more than a peduncle, each flower in the axil of a minute subulate 
bract. Nuts solitary, compressed, half exserted beyond the thickened 
and fleshy scales; aril cupular, with an irregularly crenulate margin.—
