Notes

The rhizome of Pteris atrovirens   is short and covered by dark lanceolate scales of about 4 mm long, with pale margins. The fronds are organized in tufts, from 0.25 to 1 m long. The petiole is 20 to 50 cm long, straw-colored, reddish or purple at the base. The leaf blade is elliptic-lanceolate, 20-50 cm long and 15-60 cm wide, bipinnatifid, composed of 5 to 7 pairs of lateral pinnae. Upper pinnae are opposed. The middle ones are alternate, short-stalked or subsessile, cuneate at the base, divided into about 15 rounded segments, oblong, toothed at the top, separated by narrow sinus (Fig. 14a). The pinnae apices are entire and shortly tapered on 1.5 to 2 cm. The lower pinnae are stalked, with pinnatifid auricule. The terminal pinnae are shortly decurrent. The rachis is smooth, purplish-brown. There are some soft protuberances at the upper base of pinnae (Fig. 14b). The ribs form a costal lowered areola and 1-2 series of areolas between the costa and the margin. The sori are linear. They are almost all around the lobes, up to the apex serrations. The plant prefers the banks of rivers and moist soils of forest galleries.
