Ecological life history and reproductive traits of two threatened aquatic macrophytes, Blyxa aubertii L.C. Richard and B. echinosperma (Clarke) Hooker, were studied in irrigation ponds in south‐western Japan. The size of plants varied greatly in both species but reproductive allocation was nearly constant irrespective of plant size at reproductive stage, amounting to 31.8% and 45.9% at maximum in B. aubertii and B. echinosperma, respectively. The number of flowers and total number of seeds produced per individual were associated significantly with plant size. Seeds were produced by self‐pollination both in emerged and submerged cleistogamous flowers and seed set rate of the two species was very high. These traits are considered to be adaptive to unstable environments that are liable to water level fluctuations, such as rice‐fields and irrigation ponds.

“…Kaul (1968, 1970), Ancibor (1979) and Tomlinson (1982), as well as Cook and Lüönd (1983), gave detailed descriptions of the anatomy and morphology of the genus. However, few studies have been done on their ecology except for some observations of floral biology by Cook et al (1981) and Cook and Lüönd (1983).…”

“…In Sarawak, a species of Baccaurea (Euphorbiaceae) flowering in the forest understorey was visited only by muscid flies (Nagamitsu & Inoue, 1994). In India, the dioecious aquatic herb, Blyxa octandra (Hydrocharitaceae) was visited mostly by calliphorids and muscids (Cook, Luond & Nair, 1981) and, in Hong Kong, calliphorids were the commonest visitors to two species of Lithocarpus (Corlett, 2001). A calliphorid fly, Stomorhina obsoleta, was the commonest flower-visiting insect on the Amami Islands (28.30x N), although it was considered to be of only minor significance in pollination (Kato, 2000).…”

Current knowledge of flower visitors and pollination in the Oriental Region is summarised. Much less is known about pollination than seed dispersal and the coverage of habitats and taxa in the region is very uneven. The available evidence suggests that pollination in lowland forests is dominated by highly social bees (mainly Trigona and Apis species), with beetles probably the next most important group, followed by other bees and flies. In comparison with the better-studied Neotropics, large solitary bees, moths, Lepidoptera and vertebrates are relatively less important. These differences are greatest in the canopy of the lowland dipterocarp forests of Southeast Asia, where they probably reflect the unique temporal pattern of floral resource availability resulting from 'general flowering' at supra-annual intervals. Apis bees (but not Trigona species) are also important in most montane, subtropical and non-forest habitats. Apart from the figs (Ficus spp.), there are few well-documented examples of plant species visited by a single potential pollinator and most plant-pollinator relationships in the region appear to be relatively generalised. The small sizes of most pollinators and the absence of direct human exploitation probably make pollination mutualisms less vulnerable to failure as a result of human impacts than dispersal mutualisms, but more subtle impacts, as a result of altered gene flows, are likely to be widespread. On current evidence, pollination systems in the Oriental Region do not require any specific conservation action, but this review reinforces arguments for making the preservation (or restoration) of habitat connectivity the major focus of Oriental conservation.
