D. broomensis from Coulomb Point
Range: Dampier Peninsula, Western Australia
Named after the city of Broome within its range, this species is restricted solely to the Dampier Peninsula in the Kimberley, where it grows in bare, sandy soils along the edges of seasonal waterways and permanent lakes. Plants may reach 10 cm in diameter, with a semi-erect firework rosette of slender leaves during wet season growth (dry season leaves are short, densely hairy, with reduced lamina). Petioles comprise most of the leaf length, extremely slender with a very slight taper from their base to the lamina, and become nearly glabrous in wet season maturity but otherwise have a covering of white hairs. Lamina are small and rounded to broadly elliptic, hanging out or downward from the end of the petioles. Coloration is primarily green, lamina sometimes yellowish or red-tinted and the tentacles orange to deep scarlet. Inflorescences may reach roughly 20 cm tall, with a sparse covering of thin hairs up to the peduncle where blooms are attached where it becomes glabrous and may bear up to 70 flowers. Each flower is up to slightly over a centimeter in diameter, with a clear to greenish vein in each otherwise white, narrowly to moderately obovate petal. This species can be distinguished from all of its relatives by the glabrous peduncle region of the inflorescence; all others have some form of hair covering.
Cultivation: Grow in a sphagnum and perlite or 3:1 sand/peat soil, kept moist during the growing season and year-round temperatures of 70-95°F. Should plants express shorter, hairier leaves, allow soil to dry to barely damp until wet season growth occurs. Sow seeds on soil surface (older seeds may possibly benefit from brief smokewater or GA3 treatment) and grow in strong artificial light to full sun.
Lifespan and reproduction: perennial. Reproduces through seeds and rare divisions, may possibly be grown through manual division or leaf pullings with a portion of stem attached.
