    Asplenium alleniae (Aspleniaceae), a new fern species from Borneo and New Guinea (2021)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 3, pp. 219-223
    Details
    Publication Date: 2024-01-12
    Description: A new species, Asplenium alleniae, is described from high elevation habitats in Sabah (Malaysia) and \nPapua New Guinea. Previous phylogenetic analyses of chloroplast loci determined that A. alleniae was most closely \nrelated to A. pauperequitum from New Zealand. Asplenium alleniae differs from A. pauperequitum most obviously by \nthe acuminate apices of its longer pinnae. The combination of pinnate fronds with few pairs of primary pinnae and \ndark red-brown axes distinguishes A. alleniae from superficially similar species of Asplenium in Malesia. Asplenium \nalleniae is provisionally assessed as Endangered.

    A review of the fern genus Hypolepis (Dennstardtiaceae) in the Malesian and Pacific regions (1987)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 32 no. 2, pp. 227-276
    Details
    Publication Date: 2024-01-12
    Description: Fourteen species and one subspecies of the fern genus Hypolepis Bernh. are recognised in the Malesian and Pacific regions, excluding Australia and New Zealand. Three species, H. hawaiiensis, H. malesiana and H. scabristipes, and one subspecies, H. elegans subsp. carolinensis, are described for the first time. Two widely misapplied names, H. punctata (Thunb.) Mett. and H. tenuifolia (Forst. f.) Bernh. are more clearly defined. Descriptions, distributional data and a key for identifying all fourteen species are provided. Five species, H. alpina, H. archboldii, H. bamleriana, H. malesiana and H. scabristipes, are confined to the Malesian region; four species, H. brooksiae, H. pallida, H. polypodioides and H. punctata, extend also to the Asian mainland; three species, H. dicksonioides, H. elegans and H. hawaiiensis, are confined to the Pacific region and two, H. glandulifera and H. tenuifolia, have a wide distribution from mainland Asia to the Pacific. Four species, H. dicksonioides, H. elegans, H. glandulifera and H. tenuifolia, are shared with Australia and New Zealand where a further eight endemic species occur.

    Expansion of the fern genus Lecanopteris to encompass some species previously included in Microsorum and Colysis (Polypodiaceae) (2021)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 66 no. 3, pp. 242-248
    Details
    Publication Date: 2024-05-03
    Description: The fern genus Microsorum is not monophyletic, with previous phylogenetic analyses finding three lineages to group not with the type species, but to form a grade related to the 13 species of Lecanopteris. These three lineages have recently been recognised as separate genera: Bosmania, Dendroconche, and Zealandia. Here, we explore the morphological characterisation of Lecanopteris and these other three lecanopteroid genera. While the traditional circumscription of Lecanopteris has seemed sacrosanct, its defining morphological character states of rhizome cavities and ant brooding associations occur in other lecanopteroid ferns and elsewhere in the Polypodiaceae. Instead, we suggest that the morphological characterisation of an expanded Lecanopteris including the Dendroconche and Zealandia lineages is just as good, if not better, with the pertinent character states being the absence of sclerenchyma strands in the rhizome and at least some fronds having Nooteboom’s type 5 venation pattern. This wider circumscription is also better able to accommodate phylogenetic uncertainty, and it means that groups of species traditionally placed together in a single genus are not distributed across different genera. General users familiar with the narrower circumscription of Lecanopteris will not be significantly disrupted, because there is little geographic overlap with the lineages added to the genus. Consequently, we make new combinations in Lecanopteris for 11 species and one subspecies.
