Lastreopsis Ching
Ridges of the upper surface of the main rhachis continuous with the thickened margin of the pinnae (Fig. 11). Channel of the main rhachis glanduloso-pubescent or clothed densely with articulate, reddish, unbranched hairs. Costae and costules with scattered, red or yellow, oblong or rounded, glandular hairs. Indusium mostly orbicular-reniform or rarely peltate Lastreopsis
Main rhachis clothed on the lower surface with short, soft hairs and often with dark brown, narrowly lanceolate to ovate, bullate or flattened scales; channel on the upper surface with non-club-shaped, non-glandular, acute or obtuse hairs of 3–5 cells with red or red-brown articulations. Indusium orbicular-reniform (or often orbicular in L. acuminata)
Upper pairs of primary pinnae with a basal secondary pinna arising from the main rhachis. Rhizome shortly creeping with closely spaced stipes. Sori almost marginal but never in a row around the margin. Indusium light brown, often with a dark centre; the margin glandular-fimbriate. Scales of the main rhachis dark brown, lanceolate to ovate, rarely absent. Plants 25–90 cm high. Widespread. RF or sometimes on hillsides in tall open forests Lastreopsis decomposita
Upper pairs of primary pinnae without secondary pinnae arising from the main rhachis. Rhizome short, erect or oblique, with a dense crown of fronds, covered with the broken bases of the old stipes. Sori halfway between the midrib and the margin of the segments. Indusium dark brown, almost entire, lacking glandular hairs. Scales absent on the main rhachis. Plants 25–90 cm high. Widespread. RF and tall open forests, usually near creeks Lastreopsis acuminata
