Heliamphora ionasii is a precarnivore plant from the genus of the marsh jugs ( Heliamphora ). It was named in 1978 by Bassett Maguire after its discoverer Jonah Boyan.
description
Heliamphora ionasii is a perennial herbaceous plant. Their extremely large, up to 45 cm high, at the upper end up to 18 cm wide, diagonally opened tubes stand in a down-to-earth rosette . At the base they are funnel-shaped, halfway up as if constricted and broadly funnel-shaped in the upper half. Their coloring varies depending on the location, but the base of the leaves is always reddish. In full sun to half sun, Heliamphora ionasii develops powerful pink-orange colorations with dark red veins.
On the inside of the opening, the tubes are covered with 5 to 11 millimeters long, funnel-pointing hairs . At the top there is a small, helmet-shaped lid that is slightly bent over the opening and is always dark red to purple.
Distribution and habitat
It is found exclusively in a valley of the Gran Sabana between the Ilu- and the Tramen- Tepui in Venezuela at altitudes between 1800 and 2150 m, where it occasionally occurs in association with Heliamphora elongata , with which it then also hybridizes. It colonizes full sun to partially shaded locations in deciduous humus in cloud forests .
