Flowers occur in "flower spikes", inflorescences made up of hundreds of flower pairs densely packed around a woody axis. Arising from short lateral branchlets off stems older than four years of age, the inflorescence of "B. telmatiaea" is roughly oval to cylindrical, with a height of 3–5 cm (1–2 in) and diameter of 4–7 cm (1–2 in). It contains between 500 and 900 golden brown to pale brown flowers, each of which consists of a tubular perianth made up of four fused tepals, and one long wiry style. The styles are hooked rather than straight, and are initially trapped inside the upper perianth parts, but break free at anthesis. The species generally flowers from April to August, although flowers have been observed as late as November. They take five to six weeks to develop from bud, then reach anthesis over a period of two weeks. The flowers produce unusually large quantities of nectar; indeed some flowers produce so much that it drips to the ground.
