Drosera katangensis


Range: Haut-Katanga, Democratic Republic of the Congo


This species is recorded solely from a single collection in 1912 in the eastern portion of the Congo, and has not been seen since; it may be extinct, or a synonymous term for another of the several stem-forming species in the region. It was recorded as being a helophyte, growing in a seasonal savannah-like wetland. The collection displays plants that grew to at least 15 cm in height, if not more, with potentially branching stems supporting leaves up to 3cm in length. Leaves bear narrow pubescent petioles comprising most of their length that taper to their base, and tapered ovular to elongate teardrop-shaped lamina around 1 cm long that expand out from the petiole toward the acutely rounded tip. Color is unknown. Inflorescences may reach at least 20 cm in height, densely indumentous, with at least 5-15 blooms. Flowers likely around 1 cm across, with ovoid pink petals. Primary differences from related species appears to be the more gradual transition from petiole to lamina, and highly spaced leaf arrangement on the more elongate stems as well as highly pubescent nature.


Cultivation (should the species be rediscovered): grow in in a 1:1 peat/sand or perlite mix, kept moist to waterlogged and moderately humid, with temperatures of 75-90°F year round. Sow seeds on soil surface, and grow in strong artificial light to full sun.


Lifespan and reproduction: likely perennial. Reproduces through seed and branching offshoots; may potentially be propagated via cuttings like its relatives.
