Scientific Name:
Dracophyllum longifolium (J.R.Forst. & G.Forst.) R.Br. ex Roemer & Schult., Syst. Veg. (ed. 16) [Roemer & Schultes] 385 (1819) var. longifolium

Oliver (loc. cit. 1952, 11) says: "The typical variety is a rather slender tree with long and broad juvenile leaves and long adult leaves which, along the shores of the Fiordland Sounds and in Stewart Island, hang downwards on slender branchlets." He gives lf-measurements with the range: adults 14–23 cm. × 2–4 mm., juveniles 16–24 cm. × 6–10 mm. The distribution is given as: S. Mount Arthur southwards. My measurements of lvs from adults in the Nelson area gave the range: sheaths 9–10 × 3–5 mm., mostly truncate and ± auricled; lamina 6·5–10 cm. × 1 mm.
