Notes

Pteris tripartita is a big fern, terrestrial or epiphytic, with erect, short and thick rhizome, bearing large scales. The fronds are in clumps, 1.5 to 2.5m high (Fig. 18a). The stipe is long (0,3-1,5m), very fleshy and thick. The leaf blade is ovate-deltoid, divided into three equal branches of about 1m long and 25 cm wide. These lateral branches are also divided into similar branches, making the frond pedately shaped. Each branch is bipinnate, with more than 30 pairs of pinnae of (2) 5-25 cm long and 1.3-3 cm wide. The ultimate segments are more or less oblong, straight or falciform, 0.3 to 2 cm long by 3 to 7 mm wide. The ribs form narrow areolae along costae and costulae. They are anastomosed at the ultimate lobes. The leaf blade has a thin texture and a bright green color. Sori extend from sinus to the half of the segment, or almost to the apex (Fig. 18b). This fern usually grows on rich deep soils in tropical rainforests.
