I had discovered the plants growing in December of the previous year whilst searching for the flowers of Utricularia beau - gleholei with Greg Bourke. We were hoping that the U. australis would be flowering as the water level had gradually receded. Upon arriving at the open swamp it didn’t take long to locate the U. australis .

Upon lifting some of the dried specimens we discovered that they had formed small turions on the under - sides. The turions were produced on growth points of various lengths, some up to 5cms long. The turions had been pushed into the soil by the plant, an adaptation to survive the remainder of the hot dry sum - mer.
