1. A. Colensoi, ''Hook. f. Handb. N.Z. Fl. 92.''— Stem stout, erect, 2–5 ft. high, 2–3 in. diam. at the base, deeply grooved. Radical leaves numerous, forming a circle of bayonet-like spikes round the base of the stem, 1–2½ ft. long, pinnate or 2-pinnate at the base, with few secondary leaflets; leaflets 5–15 in. long, ¼–½ in. wide or more, narrow-linear, acuminate, terminating in a long and stout spine, excessively thick and coriaceous, rigid, striate, margins rough with minute serrulations; sheaths broad, sometimes quite 2 in. across, very thick and coriaceous, produced on each side above into a spinous simple or forked narrow-linear leaflet 2–6 in. long. Inflorescence a narrow-oblong cylindrical panicle composed of numerous umbels on branched peduncles springing from the axils
