Philcoxia bahiensis

Philcoxia bahiensis is a plant from the family of plantain plants, which occurs exclusively in Brazil. It was first described only in 2000 by Vinicius Castro Souza and Raymond Mervyn Harley using a Aufsammlung of 1994. Recent works consider that they might be carnivorous.

Description

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

At the shoot axis are well over twenty leaves. The petioles have a length of 9-17 mm, are smooth and thready. The leaf blades are round and have a diameter of 1.2 to 2.5 millimeters.

The upright or ascending simple inflorescence is 14 to 25 inches high and occupies the upper portion of glands. The bracts are glabrous, ovate to triangular, 0.5 to 1.5 mm long and about 0.5 mm wide.

The flower stalks are nearly erect, 9-11 mm long and filled with about 0.2 millimeters long glandular hairs that secrete a sticky secretion. These glands are also found on the ovate to lanceolate and pointed ending sepals that are 1.5 to 2 mm long and about 0.5 mm wide. The violet, dark nervierte crown has a 3 to 4 millimeters long flower tube. The lips of the crown are circular to reverse- egg-shaped and rounded or notched at the end, the top is about 2 mm long, the lower 3 to 4 millimeters long.

The stamen is partly covered, a total of 0.5 millimeters long and smooth, the dust bag is elliptical. The ovary is also elliptical and about 1.5 millimeters long. The stylus is at the base narrow, widened abruptly toward the tip and 1.5 mm long. The round fruit capsule has a diameter of 2 to 2.5 millimeters.

Dissemination

The species is only from one location Campo rupestres in the Serra do Atalho, near Piati in the Brazilian state of Bahia known, where it grows on open sites with pure quartz sand soils that are without any other vegetation. The location, however, is created by man and goes back to diamond seekers who have the site completely dug up, natural resources and their conditions are not known.
