COMMENTS
The genus Rhaphidostichum M.Fleisch. is reported first from New Caledonia. It is characterized by smooth leaf cells, ecostate and concave leaves, abruptly narrowed in piliform acumens, with inflated alar cells of Acroporium - type ( Tan et al. 2011). Among the species present in South Asian and Malesian regions, R. piliferum is a robust plant, with branches 20-40 mm long, leaves erecto-patent to spreading both in dry and wet conditions, margins entire throughout. R. loriforme (Broth. & Geheeb) Broth. is distinguished mainly by margins serrulate in upper part including the acumen and a slender habit. Although the New Caledonian specimen ( Fig. 6 View FIG ) exhibits smaller leaf size and relatively shorter acumen, we take it
as a small form of R. piliferum with whom it shares branches 3-4 mm broad with leaves, leaf margins entire, rarely minutely serrulate at leaf shoulders, shining yellowish-green colour. The specimen is sterile and was growing on rocks mixed with Ectropothecium sodale (Sull.) Mitt. , Heteroscyphus deplanchei (Steph.) Schiffn. , Zoopsis setulosa Leitg. , Podomitrium marginatum (Steph.) Hürl. The new locality extends to the south the range of this species previously known from South Asia and Solomon Islands ( Tan et al. 2011).
