A. proliferum—pro-lif'-er-um (bulbil-bearing), Brown. d An Australian form of A. aculeatum, bearing |§ t one or sometimes two young plants at the end of its fronds. This name is also applied to a variety of A. angulare. A. pumilum—'-mil-um (small). A variety of A. angulare. A. (Polystichum) pungens—Pol-ys'-tich- um ; pun'-gens (pricking), Kaulfuss. This very pretty, greenhouse species, native of the Cape Colony and Natal, is distinguished from all other kinds closely allied to A. aculeatum principally by the wide-creeping nature of the underground rhizome (prostrate stem), from which its somewhat leathery fronds, 2ft. to 3ft. long by 9in. to lOin. broad, and borne on slightly scaly stalks 1ft. long, are abundantly produced. The fronds are spear-shaped, bipinnate (twice divided to the midrib), and furnished with numerous pinna; (leaflets) set somewhat far apart and subdivided into pinnules (leafits) that are deeply toothed and show on their edge numerous teeth of a stiff, awned nature. The sori (spore masses) are disposed principally in two rows and nearer the midrib than the edge. This species is proliferous, being usually provided at the end of its fronds with a solitary bulbil that develops into a perfect plant.—Hooker,
