Title: ON THE MORPHOLOGY AND ANATOMY OF TWO SPECIES OF LEPISORUS (J. SMITH) CHING: L. THUNBERGIANUS (KAULF) CHING, AND L. EXCAVATUS (BORY) CHING
Abstract: Morphological and anatomical studies of two species of Lepisorus (J. Smith) Ching, L. excavatus (Bory) Ching and L. thunbergianus (Kaulf) Ching, are described in detail for the first time. Both the plants are epiphytic with small, creeping rhizomes, bearing branched roots and two rows of simple, lanceolate, glabrous, short-petioled leaves. In both cases the roots are diarch, the rhizomes are dictyostelic, and the petioles have many vascular bundles. Leaves have a T-shaped xylem. Large, rounded exindusiate sori are arranged on either side, close to the midrib, in two rows. Sporangia are leptosporangiate and protected by peltate paraphyses. Monolete, bilateral spores with a two-layered granulate exine are present.
