Philcoxia bahiensis is a plant from the family of plantain plants that occurs exclusively in Brazil. It was first described in 2000 by Vinicius Castro Souza and Raymond Mervyn Harley based on a collection from 1994. Recent work suggests that itcould be carnivorous .

description

Philcoxia bahiensis is a perennial , herbaceous plant with a stature height of up to 25 centimeters and short, subterranean shoot axes that are sparsely and irregularly branched and reach a thickness of 1.5 to 3.5 millimeters. The rhizomes are leafless, the roots reach a thickness of 2 to 3 millimeters.

There are well over twenty leaves on the stem axis . The leaf stalks have a length of 9 to 17 millimeters, are smooth and thread-like. The leaf blades are round and 1.2 to 2.5 millimeters in diameter.

The upright or ascending simple inflorescence is 14 to 25 centimeters high and has glands in the upper section . The bracts are hairless, ovate to triangular, 0.5 to 1.5 millimeters long and around 0.5 millimeters wide.

The flower stalks are approximately upright, 9 to 11 millimeters long and covered with around 0.2 millimeter long glandular hairs that excrete a sticky secretion. These glands are also found on the ovate to lanceolate and pointed sepals that are 1.5 to 2 millimeters long and around 0.5 millimeters wide. The purple, darker nerved crown has a 3 to 4 millimeter long tube. The lips of the crown are circular to inverted egg-shaped and rounded or notched at the end, the upper one is about 2 millimeters long, the lower 3 to 4 millimeters long.

The stamen is partially fused, a total of 0.5 millimeters long and hairless, the anthers are elliptical. The ovary is also elliptical and around 1.5 millimeters long. The stylus is narrow at the base, widened suddenly towards the tip and 1.5 millimeters long. The round capsule fruit has a diameter of 2 to 2.5 millimeters.

distribution

The species is only known from one location in Campo rupestres in the Serra do Atalho , near Piati in the Brazilian state of Bahia , where it grows in open locations with pure quartz sand soils that are devoid of any other vegetation. However, the site was created by human hands and goes back to diamond seekers who have completely dug up the site, natural occurrences and their conditions are not yet known.
