About Diuris decrementum D.L.Jones & C.J.French
Diuris decrementum is a tuberous, perennial herb that typically grows between 80 and 300 mm (3 to 10 inches) in height. Two to five leaves emerge from its base, each measuring 50 to 120 mm (2 to 5 inches) long and 1 to 2 mm (0.04 to 0.08 inches) wide. It produces up to three yellow flowers marked with brown blotches, each 8 to 12 mm (0.3 to 0.5 inches) wide. The flowers have broad, ear-shaped petals, an upright tapering dorsal sepal, and narrow, forward-pointing lateral sepals. The labellum is divided into three lobes: the lateral lobes are small and spreading, while the middle lobe is elongated and has a raised mid-line. Flowering takes place from late August to early November. This species, commonly called the common bee orchid, occurs from the area near Perth to east of Esperance, and grows in a range of habitats including woodlands and soil pockets on granite outcrops.
