Heliamphora minor (Latin: minor = smaller) is a species of marsh pitcher plant endemic to Auyán-tepui in Venezuela. As the name suggests, it is one of the smallest species in the genus. It is closely related to H. ciliata and H. pulchella.
Cultivation
Heliamphora minor is one of the more widely available species in the genus for cultivation. Typically, H. minor is grown under strong fluorescent lights in a terrarium, or in a greenhouse with partial sunlight. Like other carnivorous plants, H. minor requires water free from added minerals and chemicals. It can survive a wide range of temperatures, preferably around 70-90°F, however during the night the temperature must drop to around 10 degrees less than the day temperature. Soil for H. minor must be low in nutrients. Combinations of washed sand, orchid bark, long fibered sphagnum moss (dried or living), peat moss, and perlite may be used. Heliamphora plants also require a high humidity level, which can be achieved in a greenhouse or terrarium.[citation needed]
Infraspecific taxa
Two varieties of H. minor are recognised: the autonym H. minor var. minor and H. minor var. pilosa, which is characterised by conspicuous hairs on the pitcher exterior.[2][3][4][5]
Heliamphora minor f. laevis, described by Julian Alfred Steyermark in 1984, is considered a synonym of H. minor var. minor.[3]
