Descriptions
Dicksonia squarrosa (G.Forst.) Sw.
Rhizomes spreading from main stock to 1 m. or more, giving rise to subsidiary erect caudices, often forming a grove. Caudex slender, up to c. 10 cm. diam., up to 6 m. or more tall, invested by long-persistent bases of stipites; bearing dormant buds near base, or these developing into short or long branches. Stipes densely clad in deciduous dark filiform hairs up to 4 cm. long; roughened by enlarged persistent bases of fallen hairs. Rhachis clad in dark reddish brown hairs when young, becoming rough in age. Lamina 10-25 dm. long, about oblong-lanceolate, 2-3-pinnate, coriac. Primary pinnae 25-50 cm. long, deltoid-ovate, acuminate; secondary rather close-set, 5-8 cm. long, acute. Fertile pinnules close-set, confluent at base, 10-15 mm. long; lobes strongly concavo-convex c. 5 mm. long, rounded, each bearing a sorus. Lobes of barren pinnules shallowly concave, acute, us. sharply toothed. Indusium rather delicate, concavo-convex.
