    Bangladesh Academy of Sciences ; 2023

    Abstract: Hypodematium shandongense is closely related to Hypodematium jianxiuii X. J. Li. Results of LM and SEM studies showed that there were significant differences between the two species. Plant height of Hypodematium shandongense is 22-30 cm, laminae ovate-triangular, pinnae are closely arranged, fronds, rachis, costae and the indusia are characterized by sparsely long acicular and rod-shaped glandular hairs, perispore semi-annular folds; but the plant height of H. jianxiuii is 60-70 cm, laminae ovate-pentagonal, pinnae are sparsely arranged, fronds sparsely covered with short acicular hair adaxially, abaxial fronds, rachis, costae and the indusia are densely covered with pubescence and glandular hairs, and perispore tuberculate protrusion.

    Abstract: A combination of plant taxonomy, micromorphological and palynological characters was used to systematically compare and study the status of the two closely related species, namely Dryopteris laoshanensis and D. championii. Results showed that the sporophylls of D. laoshanensis were triangularovate, with 1 alternate pair of pinnae at the base of the sporophylls, not shortened, and each alternate pair of pinnae gradually shortened upward; rhizome and petiole are densely covered with reddish brown ovatelanceolate scales; the sori are distantly placed from the main vein; spore perispore with curved ridges protrusions, which is clearly different from the D. championii. The leaves of D. championii were ovateoblong, 1 pair of pinnae at the base of the leaves slightly shortened, and the upper 2-4 pairs of pinnae were extended in sequence, which is the widest part of the leaves at the middle, and then the pinnae gradually shrinking upward; rhizome and petiole are densely covered with dark brown lanceolate scales; the sori close to main vein; spore perispore with tuberculiform and tuberculiform-rugulate protrusions. It provided micromorphological and palynological evidences for the clear identity of D. laoshanensis and D. championii as distinct species. Bangladesh J. Bot. 51(4): 863-871, 2022 (December) Special
