5. Holomitrium cylindraceum (P. Beauvois) Wijk & Margadant

[ Dicranaceae ]

[syn. H. vaginatum (Hooker) Bridel , H. javanicum Dozy & Molkenboer ]

The genus is distinctive in the family Dicranaceae in having rather large perichaetial leaves enfolding ⅓ the length of the seta. The leaves have round to oval, thick-walled laminal cells, and the leaf alar consists of numerous quadrate, also thick-walled and colored cells. The habit illustration of this species in Gao et al. (1999, Plate 49) with long acuminate leaf apices is misleading. Accurate illustrations of this species are found in Fleischer (1904, as Holomitrium javanicum ), Bartram (1939, as H. vaginatum ) and Eddy (1988, as H. vaginatum ). The species has a wide distribution from eastern Africa to Malesia and Polynesia ( Eddy 1988). Before the present report of this species from Mindanao, Holomitrium cylindraceum had been reported from Luzon and Mindoro (Tan and Iwatsuki 1991).
