Genlisea

GENUS: Genlisea

A genus related to both Utricularia and Pinguicula (with these 2, the family Lentibulariaceae is complete,) with perhaps the strangest trapping method of all the carnivorous plants. The underground traps are in the form of twisted spirals with a rim of hairs allowing entry to small creatures, but obstructing their exit. As they struggle, they work their way along the spiral until they arrive at the 'stomach' - a bulbous enlargement of the stalk the spirals are mounted on, where they are digested by proteolytic enzymes.

SPECIES: G. hispidula - Common Name: None - Distribution: Africa

A larger and easier plant than G.violacea, producing white flowers variably blotched with lilac, yellow, orange, on long scapes. Forms clumps of leaves 1-2" diameter fully grown, traps up to 6" long. Propagates well from leaf cuttings or seed. Cultivation as for G.violacea, but not so fussy as regards temperature and lighting. I grow mine in small pots mounted in jamjars, so the traps hang down into water - this shows them off to good advantage, as they are the most interesting feature of the plant.

SPECIES: G. repens - Common Name: None - Distribution: Brazil

Appearance and cultivation as for G.violacea, but this sp. is an annual in habitat and produces yellow flowers. Under ideal conditions the plant will multiply by the formation of stolons, and can be grown perennially if a summer photoperiod is used all year. Difficult, so not recommended for beginners.

SPECIES: G. violacea - Common Name: None - Distribution: Brazil

Small-leaved perennial forming a tight clump, producing white - purple flowers sporadically. Smaller than G.hispidula, and cannot be propagated from leaf cuttings, though trap cuttings have been known to work occasionally. Best grown as a terrestrial marginal in 1:1 peat:sand, with the water level at the level of the soil, full sun, temps not to exceed 30ºC. Keep frost-free. If under artificial lighting, provide 11-14 hr photoperiod winter - summer for optimum growth. More difficult than G.hispidula, but easier than G.repens.
