Heliamphora sarracenioides is a species of the marsh jugs ; it is a carnivorous ( precarnivore ) plant. The species was only discovered in January 2004 by a German expedition in Venezuela .
description
The plants of the species have a branched rhizome. The seeds are approximately 1.5 mm long, egg-shaped and winged.
leaves
The leaves of the plant are up to 30 cm in size, up to 5 cm in diameter, but only up to 3.5 cm wide at the opening, green to deep red tubes depending on the sun. These differ in shape from the funnel-shaped leaves of other Heliamphora and are more similar to those of the red pitcher plant ( Sarracenia purpurea ). This impression is particularly reinforced by a wide “lid”, which is up to 4 by 5 cm in size and slightly kinked over the often smaller opening of the tube and is covered with glands up to 0.2 mm in size. The upper part of the leaf interior is smooth and hairless, and clearly delimited from the lower, hairy part.
blossoms
On the up to 60 cm long, hairless flower stalk there are usually two to three single flowers on up to 5 cm long pedicels covered with stipules , whose lanceolate, white to pink-colored petals are four cm long and two cm wide. They comprise ten 5 to 6 mm long stamens long with 7 to 8 mm and 1.5 mm wide, oblong -lanzettlichen anthers . The rather unusual length of the anthers for the genus suggests a closer relationship with Heliamphora heterodoxa and Heliamphora folliculata .
distribution
The species is native to several Venezuelan tepuis and the Gran Sabana .
etymology
The name Heliamphora is composed of the Greek names for swamp and pitcher , the sarracenioides refers to the unusual, tubular plant-like appearance of the species.
