Cottendorfia florida is the only species of the genus Cottendorfia in the subfamily Navioideae withinthe bromeliad family (Bromeliaceae). Previously they were classified in the subfamily Pitcairnioideae .

description

In Cottendorfia florida is a terrestrial , perennial herbaceous plant that forms sometimes by vegetative propagation stocks.

The grass-like leaves stand together in basal rosettes . The leaf sheaths are only indistinctly developed. The simple leaf blades are up to 1 meter long, 1.2 centimeters wide, narrow-linear and taper into a spike tip. The leaf margin is smooth and unreinforced. The underside of the leaf is densely covered with white scale hairs.

Cottendorfia florida forms a 2 to 4 meter long inflorescence stem. The up to 40 centimeters long, loosely branched, woolly hairy total inflorescence consists of annual, up to 6.5 centimeters long partial inflorescences. The inconspicuous bracts are narrow triangular and the bracts are rarely longer than 2 millimeters. Flower stalks are hardly recognizable. The small, only 7 millimeters long, hermaphrodite flowers are threefold. The three free, broadly ovate, blunt sepals are about 3 mm long and hairless. The left side of each sepal covers the right side of the next. The three free petals are whitish, elliptical and blunt. There are two circles with three free stamens each. Three carpels have become a top permanent ovary grown. The stylus is slim.

The flower formula is: or

Egg-shaped, tripartite capsule fruits are formed. The narrow seeds have two appendages.

Occurrence

Distribution area is northeastern Brazil on the Guiana Highlands in dry areas in the states of southern Piauí and in Bahia only in the Serra do Sincorá . They thrive on rocky locations at altitudes of around 1200 meters.

Systematics

The genus Cottendorfia was described in 1830 by Julius Hermann Schultes and Joseph August Schultes in JJ Roemer & JA Schultes: Systema Vegetabilium , 7 (2): lxiv, 1193 with the species Cottendorfia florida . The generic name Cottendorfia honors Johann Georg Freiherr Cotta von Cottendorf , a German patron of the natural sciences (1796–1863).

Since molecular genetic studies showed that the subfamily Pitcairnioideae was not monophyletic in its original extent, it was divided into several subfamilies. The subfamily Navioideae was reactivated with the genera Brewcaria , Navia , Sequencia , Steyerbromelia and Cottendorfia . With the exception of Cottendorfia florida , the other species classified here have almost all been placed in the genus Lindmania, reactivated by Lyman B. Smith in 1986, or a few in the genus Fosterella and thus belong to a different subfamily.
