Habitat:
Locally established along the open margin of a small wetland. Sometimes occurring as discrete plants, with occasional larger patches (30 cm x 30 cm or more). Collectively about 1 square metre in extent. Growing as individual plants or as a discontinuous loose mat among Gonocarpus micranthus, Leptinella squalida subsp. squalida and other wetland flora. Because top-soil has been scraped off, the exposed gently-inclined clay surfaces are wet (occasionally inundated) and relatively infertile, resulting in very little exotic grass encroachment and in dominance by wetland turf species. The area is subject to occasional light grazing by sheep, which further suppresses exotic grasses. The wetland lies near the base of a hill-slope supporting black beech forest, which would originally have graded into wetland swamp forest dominated by kahikatea and pokaka on adjacent flatter surfaces (such as the wetland location).
Microhabitat:
The wetland margin is an ecotone dominated by Eleocharis acuta, Myriophyllum triphyllum, Ranunculus glabrifolius and Lilaeopsis ruthiana (on wetter side) grading to Lobelia angulata, Gonocarpus micranthus, Euchiton sp. (possibly E. ensifer) and Gratiola concinna (on intermediate scraped surfaces), to exotic grasses (on drier un-scraped surfaces). Other flora growing sporadically beside Euchiton sp. (possibly E. ensifer) includes Leptinella squalida subsp. squalida, Euchiton limosus, Hypericum pusillum, and Plantago triandra. Drier margins (retaining original soils) are dominated by occasional emergent rushes over exotic grasses, mosses (particularly Calliergon cuspidatum) and Leptostigma setulosum.
