Acanthostachys species grow upright to pendulous, as relatively small, evergreen, perennial herbaceous plants and are somewhat xerophytic . They form small clumps through short, sparsely protruding runners . They live epiphytically or terrestrially .
A few coarse, parallel-veined, up to 1 meter long, narrow leaves sit loosely together in a basal rosette on a compressed main axis. The leaves are reinforced by a serrated leaf margin. The leaves have suction scales at least on the underside of the leaf.
In acanthostachys strobilacea just something to sit on the upright to overhanging inflorescence stem prickly leaves that are similar to the basic blades are smaller. In Acanthostachys pitcairnioides the inflorescence stem is very short. At the end of the shaft there is a cone-like, heady, all-round, spiked inflorescence that looks very much like a pineapple , without a terminal tuft of leaves. The flowers sit individually between the bracts.
The small flowers are radial symmetry and threefold. The three sepals are free. The three yellow ( Acanthostachys strobilacea ) or blue ( Acanthostachys pitcairnioides ) petals are free up to their base. There are two circles with three stamens each. Three carpels have become an under constant ovary grown.
The flower formula is .
There are berries formed which are adherent to a collecting fruit (= Syncarpium); it is less than 10 centimeters.
use
Almost only Acanthostachys strobilacea is occasionally in culture. It is suitable as a houseplant (also as a traffic light plant), as it is very easy to care for and is relatively small. Since they are very robust, are not eaten by most animals and are completely non-toxic, they can be recommended for terrariums . The multiplication takes place through Kindel .
The small fruits are edible and taste sweet.
Systematics and distribution
The genus Acanthostachys was established by Klotzsch in 1841 . The botanical name of the genus Acanthostachys is derived from the Greek words ákanthos for prickly plant and stáchys for ear, ie "prickly-eared" and refers to the unusual habitus for bromeliads .
Their areas range from Brazil to Paraguay and Argentina .
With some authors the genus Acanthostachys is still given as monotypic . There are only two species of Acanthostachys :
- Acanthostachys pitcairnioides (Mez) Rauh & Barthlott : It was first described in 1982. It has a smaller distribution area in the Brazilian states of Bahia and Espírito Santo .
- Acanthostachys strobilacea (Schultes f.) Klotzsch ( strobilacea for cone-shaped, syn .: Acanthostachys exilis Bertoni ): It thrives epiphytically and lithophytically at altitudes of 750 to 800 meters from Brazil to Paraguay and Argentina.
