Isotoma (Campanulaceae) 2:411 (as Lobeliaceae)




Tasmania has two very similar native species of Isotoma I.fluviatilis and I. tridens. Both are small creeping herb, with small, dark green leaves. They are found in wet places such as the edges of lakes where they are subject to occasional inundation.
Their flowers have bilateral symmetry and the anthers are joined edge to edge to form a tube around the style.
