Heliamphora ionasi

Heliamphora ionasi is a species of marsh pitcher plant thought to be endemic to the plateau that lies between the bases of Ilu Tepui and Tramen Tepui in Venezuela. It produces the largest pitchers in the genus, which can be up to 50 cm in height.

The species was discovered by a team led by Bassett Maguire and comprising, among others, Jonah Boyan. The specific epithet ionasi is based on a Latinised form of Boyan's first name. A photograph by Maguire showing Boyan holding a specimen of H. ionasi was featured on the front cover of the September 1979 issue of the Carnivorous Plant Newsletter.
