1. P. trichomanoides, ''D. Don. in Lamb. Pin.'' ed. ii. App.—A tall graceful tree 50–70 ft. high; trunk 1–3 ft. diam.; branches whorled, slender, spreading. Cladodes or flattened leaf-like branchlets alternate and distichous on whorled rhachises 1–3 in. long, each rhachis and its cladodes resembllng a pinnate leaf; each cladode ½–1 in. long, obliquely cuneate or rhomboid, thick and coriaceous, lobed or pinnatifid, the lobes truncate or erose; veins spreading. Leaves of seedling plants ½–¾ in. long, narrow-linear, soon deciduous; of older plaints reduced to minute subulate scales at the base of the rhachises of the cladodes or of the cladodes themselves. Flowers monœcious. Males in fascicles of 5–10 at the tips of the branchlets, ⅓–½ 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 mmute subulate bract. Nuts sohtary, compressed, half exserted beyond the thickened and fleshy scales; aril cupular, with an irregularly crenulate margin.—''A. Cunn. Precur. n. 326; Raoul, Choix, 41; Hook. Ic. Plant. t. 549, 550, 551; Hook. f. Fl. Nov. Zel. i. 235; Handb. N.Z. Fl. 259; Kirk in Trans. N.Z. Inst. x. (1878) 381; Forest Fl. t. 6, 7; Pilger in Pflanzenreich,'' iv. 5, 97. P. rhomboidalis, ''A. Rich. Fl. Nouv. Zel. 363 (not of L. C. Rich.)''.

2. P. glaucus, ''Carr. Trait. Gen. Conif.'' 502.—A small handsome tapering tree 25–40 ft. high; branches stout, whorled; trunk 12–18 in. diam., rarely more. Cladodes or flattened leaf-like branchlets alternate and distichous on a rhachis 4–12 in. long, glaucous when young, 1–2½ in. long, rhomboid or obliquely ovate-cuneate, extremely coriaceous, deeply or coarsely toothed or lobed, lobes obtuse or acute. True leaves on seedling plants ½–1 in. long, linear,
