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.

Juncaginaceae are a small monocot family of mostly coastal and wetland herbs of almost cosmopolitan distribution. A phylogenetic analysis of the family and members of Alismatales was conducted to clarify the circumscription of Juncaginaceae and to understand intrafamilial relationships. For the first time, all genera associated with the family in the past were analysed together. Two plastid (rbcL and matK) and one mitochondrial gene (atpA) were sequenced. The separate and combined analysis of the three markers showed that Juncaginaceae are not monophyletic in their current circumscription. The family is re-circumscribed to exclude Maundia which is proposed to belong to a separate family Maundiaceae. In the new classification Juncaginaceae comprise three genera: Tetroncium, Cycnogeton, and Triglochin. Tetroncium is weakly supported as sister to the rest of the family. The reinstated Cycnogeton (formerly included in Triglochin) is highly supported as sister to Triglochin s.s. The enigmatic Lilaea is nested within Triglochin s.s. and highly supported as sister to the T. bulbosa complex. The results of the molecular analysis are discussed in combination with morphological characters. A key to the genera of the family is presented, and six new combinations are proposed: Cycnogeton alcockiae, Cycnogeton dubium, Cycnogeton microtuberosum, Cycnogeton multifructum, Cycnogeton rheophilum, and Triglochin scilloides.
