A numerical analysis of intraspecific variation within the Triglochin procera aggregate in Victoria suggests four morphologically distinct forms. Cytological studies indicate the polyploid series 2n = 16, 32, 64, the counts corresponding to three of the morphological forms. The diploid. designated form A. is found in north-central Victoria. It has distinctively small fruits, with 4-6 carpels. The pericarp is membranous, and the seed testa brown, hard and three-ridged. Flowering scapes are reddish. in comparison with the green scapes of the other forms.

The tetraploid, designated form B, found in Gippsland, has globose, smooth, untwisted fruits on very short pedicels and terete leaves and scapes. In common with form C, it has a constant carpel number of 6, fruit with a fleshy pericarp, and seed with a smooth, pale, soft testa.

The octoploid; form C, is the most widely distributed and the most variable form, particularly with regard to leaf morphology and degree of twisting of the carpels. Leaves are generally fleshy and broad, but may be thinner and trailing in fast-flowing water. Fruits are large.

The fourth morphological form; D, is also an octoploid, with fruits like form C, but it has thin trailing. submerged, conspicuously veined leaves which contrast with the robust. emergent leaves of the other forms. It is found in the fast-flowing streams of east Gippsland.

The Juncaginaceae is a small cosmopolitan family of usually aquatic herbs. Current world wide reviews of the family list approximately 12 species and 4 genera in the family with the centre of diversity in South America. In Australia the family is considerably more speciose than previously recognized. Taxonomic and ecological studies in Eastern Australia have shown that there are 12 perennial taxa present in freshwater environments. Recent ecological and biological studies in south Western Australia have established that at least 15 annual taxa are present, many of which are endemic to this area. These findings clearly establish Australia as the world centre for species diversity in the family. The eastern and western perennial taxa are aquatic, wind pollinated, largely outbreeding with a high degree of polyploidy present. The Western Australia taxa are mainly small, effectively terrestrial annuals of winter damp sites. These taxa are usually diploid, wind pollinated, capable of inbreeding and frequently occur in naturally saline sites. Their small size enables large populations to be present in micro-habitats and often several taxa co-occur. Most members of the annual group have specialized epizoochorous fruits, compared to the water-dispersed fruits of the perennials. The phytogeography of the family is compared to other speciose monocotyledon families (Anthericaceae, Centrolepidaceae, Cyperaceae and Restionaceae) of Western Australia.
