PLANT Utricularia lateriflora Small Bladderwort AUS SA AMLR Endemism Life History Pre-1983 AMLR filtered records from Cleland, Mylor, - V E - Annual Myponga, Tunkalilla and Inman Valley areas, and multiple records around Mount Compass.4 Family LENTIBULARIACEAE Surveys in 2008 found a single population. Attempts to relocate populations at other known sites were unsuccessful (J. Quarmby pers. comm. 2009). Habitat Occurs in damp areas, whether damp sand or black boggy soils, in higher rainfall areas of the region (T. Croft pers. comm.).3,6 Recorded from Fleurieu Peninsula swamps in peatlands (forest, shrub or open bogs) of: Leptospermum continentale shrubland with sedge and fern understorey Leptospermum shrubland with emergent Viminaria juncea or Acacia retinodes and sedge Photo: © Ron Taylor understorey Leptospermum continentale and Sprengelia Conservation Significance incarnata shrubland with sedge understorey The AMLR distribution is disjunct, isolated from other Phragmites and/or Typha grassland with extant occurrences within SA. Within the AMLR the emergent Viminaria juncea, Acacia retinodes species’ relative area of occupancy is classified as and sedge understorey.8 ‘Very Restricted’. Relative to all AMLR extant species, the species' taxonomic uniqueness is classified as Within the AMLR the preferred broad vegetation group ‘Very High’.4 is Wetland.4 Description Within the AMLR the species’ degree of habitat Small, herbaceous, carnivorous bladderwort (T. Croft specialisation is classified as ‘Very High’.4 pers. comm.). Up to 10 cm tall with inconspicuous leaves. One to eight flowers, pale-lilac to violet in Biology and Ecology colour, with a white or yellow spot at the base of the Flowers from November to March.3 In the Fleurieu lower lip.3,9 Peninsula behaves as an annual but may have perennial underground stolons. Appears to grow back Distribution and Population in the same locality each year (R. Taylor pers. comm.). Also occurs in QLD, NSW, VIC, TAS and NT. In SA occurs in SL, KI and SE regions.1,2 Recorded as having a robust fire response, i.e. a species least likely to be affected by repeated fires.5,7 Plant of the Fleurieu Peninsula swamps, recorded Re-sprouted after fire at Glen Shera swamp (R. Taplin from Higgs Swamp, Tookayerta and Finniss pers. comm.) Catchments (Yundi, Nangkita Swamps), Seabrook Swamps, Glen Shera Swamp (now Stipituris CP).8 Also Considered drought-tolerant in NSW.9 recorded from a private property in Heathfield (K. Brewer and J. Smith pers. comm.). Aboriginal Significance Post-1983 records indicate the AMLR distribution occurs Post-1983 AMLR filtered records mostly distributed in Peramangk, Ngarrindjeri and Kaurna Nations.4 around Mount Compass; also recorded at Deep Creek CP, Mount Billy CP, Hindmarsh Falls Reserve and Scott Creek CP.4 Further information: Biodiversity Conservation Unit, Adelaide Region Phone: (61 8) 8336 0901 Fax: (61 8) 8336 0999 http://www.environment.sa.gov.au/ Department for Environment and Heritage FIS 90346 May 2008 Prepared as part of the Regional Recovery Plan for Threatened Species and Ecological Communities of Adelaide and the Mount Lofty Ranges, South Australia 2009 - 2014 Threats Br.
