Habitat

edit

Its natural habitat is subtropical or tropical moist lowland forests on the Atlantic side of the isthmus. It is threatened by habitat loss.[5][6][7][8]

Description

edit

Zamia pseudoparasitica is the only known species of Zamia that is epiphytic.[9] Furthermore, it is the only known obligate epiphytic gymnosperm.[10] growing on the branches of forest trees. It has a very short trunk but long leaves over 3 m long. The seeds are orange.

The root system can be very long and may reach and root in the ground in some cases. Taproots of 15 m in length have been documented.[11]

Cytology

edit

The diploid chromosome count of Zamia pseudoparasitica is 2n = 16.[12][13]

Ecology

edit

Pollination

edit

The beetle Notorhopalotria taylori appears to be the main pollinator of Zamia pseudoparasitica.[10] The beetle lives in the male cones of Zamia pseudoparasitica.[14]

Seed dispersal

edit

The seeds are thought to be disseminated by northern olingo,[9][15]Toucans,[9] or potentially by fruit-eating bats.[10]

Conservation

edit

Primary forest is an important habitat for this species, as it has been unable to re-colonize secondary forests within a timeframe of 50 years.[10]

Horticulture

edit

Some attempts have been made to bring the plant into cultivation as a plant to be grown in a hanging basket, with some degree of success.[16][17][18][19] Watering should be done with soft, slightly acidic water. The substrate, which may be composed of coco chips, bark, moss, and anorganic materials like pumice and perlite, should be kept moist and should not dry out completely.[20]
