Campylosiphon purpurascens is a mykoheterotrophic , leaf-greenless plant species and one of two species of its genus fromthe Burmanniaceae family . When found, the plants are often confused with plants of the genus Voyria .
description
Campylosiphon purpurascens is an upright and herbaceous species and reaches heights of between 7 and 33 centimeters. The cylindrical rhizome is bulbous , densely covered with stiff scale leaves at the extreme point and densely rooted in the middle and at the base.
They do not carry out photosynthesis , but live mykoheterotrophically on mycorrhizae and are completely dependent on them for their nutrition.
The numerous narrow-egg-shaped to linear-egg-shaped scale sheets are 3.5 to 19 millimeters long and 1.4 to 4.8 millimeters wide. The flower stalks are pale blue and unbranched, the inflorescences are forked, two- to eight-flowered coils and 17 to 67 millimeters long or - rarely - terminal single flowers. The bracts are narrow-egg-shaped, 5 to 16.3 millimeters long and 1.5 to 4.5 millimeters wide.
The flowers are erect, tubular, stalked, 16 to 28 millimeters long, fragrant and pale purple to white. The capsule fruits are white to blue-white, narrow-elliptical to narrowly inverted-ovoid, 6.5 to 14.5 millimeters long and 1.9 to 4.5 millimeters wide.
distribution
Campylosiphon purpurascens is native to tropical South America and can be found from Peru to Guyana and south to Brazil. There it grows in rainforests, in Guyana in Mora forests, along the banks of running waters on sandy soils at altitudes from sea level up to 460 m.
Related species
In 2010 Maas placed the species previously listed under Burmannia congesta in the genus Campylosiphon . It then bears the name Campylosiphon congestus (CHWright) Maas and occurs from tropical West Africa to Angola .
