​
This pygmy sundew is an endemic to a relatively small region surrounding the Bindoon Training Area, hence the name. Plants are found in relatively dry, rocky laterite soils, growing as relatively flat rosettes of paddle leaves up to 2 cm across. Petioles are roughly even width along their length, narrowing slightly at the lamina connection, and roughly glabrous save for a few small glands on the lower surface. Lamina are ovate-orbicular, with lengthy marginal tentacles at the distal end. Coloration is typically green with crimson lamina and tentacles, producing a bicolor appearance. Inflorescences are typically 3-4 cm in height, glabrous in the base and with red-tipped white hairs increasing in density upward through the top portion, and may bear up to 8 blooms. Flowers are nearly 2 cm in diameter, petals roughly obovate in shape but with truncate or toothed tips and brilliantly metallic orange in color with a red-edged black base forming a dark flower center. This species frequently goes dormant in the wild during its fully dry summer season, dying back to a shaggy ovoid stipule bud. It can be distinguished from its closest relatives by its shorter inflorescence, truncate-crenate petal tips, and slender red-tipped stigmas as well as erect fruits.
​
Cultivation: Best grown in a loose mix of 3:1 sand/perlite and peat, or laterite gravel if available. During growing season keep just moist and moderately humid, with temperatures of 45-70°F. During summer, plants are best kept moist but with increased temperature and photoperiod; if allowed to dry, dormant plants are difficult to revive in some cases. Seeds may require special treatment such as scarification, hot stratification, or GA3 treatment to germinate, and should be sown on the soil surface. Grow in strong artificial light to full sun.
​
Lifespan and reproduction: short-lived perennial. Reproduces via seeds (may require separate clones), gemmae, and can be propagated via leaf pullings.
