Lagrave, 18 Jan. 1974, D. Lorence s.n. (holo-: MAU- 0009282!). Short description Epiphytic; long-creeping filiform rhizomes, rootless and densely covered by dense black trichomes, bearing widely separated pending fronds; fronds with terete wingless stipes, and rare proliferation, up to 2.5 cm long, flabellate, palmatisect to digitate (less often pinnatifid), with sometimes, when dry, folds parallel to veins; sori few, paratactic, tubular to funnelform with a slightly dilated mouth. Global distribution Western Indian Ocean (the type variety is widespread from Africa to Pacific islands). Distribution in Comoros Anjouan, Grande Comore, Mayotte. Additional specimens examined COMOROS: ANJOUAN, s. loc., 1850, L.H.Boivin s.n. (P00139635). GRANDE COMORE, Forêt de la Grille, May 1963, J.Bosser 17982 (P00139636). MAYOTTE, s. loc., 1882, E.Marie s.n. (P00139634). Note The dwarf C. minutum (with digitate to flabellate fronds that rarely exceed 3 cm long) is usually distinguished by the presence of buds on stipes which can develop to provide a new frond, a feature called ‘stipe proliferation’ (the synapomorphy of sect. Gonocormus ; Ebihara et al. 2006 ). However, the Comorian specimens do not exhibit such features. They could thus correspond to C. minutum var. mascarenensis that describes lowland populations of dwarf specimens without proliferation ( Pynee et al. 2012 ).
