Description
Distribution and Ecology - Distribution: Thailand, peninsular Malaysia and Bomeo (Fig. 96).Ecology: Campylopus serratus is the only species ofthe genus to occur at low elevations in Malaysia. The other species of the genus mostly occur above 800 m. The present species has been collected from sealevel to 1100 m but the majority of the collections come mostly from below 200 m. It occurs on exposed or semi-exposed, moist sandy or peat soils.

Discussion
Figs. 68-73.
Johnson (1962) published a note on the widespread occurrence of a sand-binding moss on the east coast of Malaya and she had identified the species as Racelopus pilifer. Touw (1986) expressed doubt about the identity of this species. Johnson did not mention any voucher specimen and in addition, the figures given in the paper are not helpful in confirming the identity of this species. However, there are three specimens collected by Johnson (4021, 4023 and 4026) at KLU and identified by her as Racelopus pilifer. These specimens collected on the east coast of Malaya are in fact C serratus. W e have not been able to see other specimens identified as R. pilifer by Johnson.
Campylopus serratus is related to C. savannarum (C. Müll.) Mitt., a pantropical species, which has recently been recorded from Southeast Asia (Frahm, 1984b, 1985; Hegewald & van Zanten, 1986). The present species differs only in the lack of a border of quadrate cells at the basal leaf margin, which is replaced by two rows of hyaline narrow rectangular cells. Thus C. serratus may be interpreted as geographical vicariant race of C. savannarum in Southeast Asia, probably developed as a result of isolation by the breaking of the Gondwana plate. Such similar relationships are also found in the species pairs C. fragilis-crispifolius and C. flexuosus-comosus.
