Appearance and leaves

The Quesnelia species are perennial herbaceous plants . Specimens of the same species grow as epiphytes or terrestrially. These are funnel or cistern bromeliads. They are small to large species with a funnel diameter of 0.2 to 1 meter. The tough leaves end in a spike tip. The leaf margins are always reinforced at the edge (as with all representatives of the Bromelioideae). Suction scales can mainly be seen on the underside of the leaf, but are also found on the upper side of the leaf in the lower area below the water surface. Large amounts of water often collect in the leaf funnels. In many funnels there are small biotopes with several species of animals, algae and aquatic plants.

Inflorescences, flowers and fruits

In up to 1 meter long, upright to overhanging, mostly handsome, simple, spiked inflorescences (inflorescences) that can only last for a short time , the many flowers are arranged in a cylindrical, densely or loosely manner. As a specialty, Quesnelia lateralis forms additional, apparently lateral inflorescences (hence the specific epithet ), but they are Kindel, which develop hardly recognizable leaves and are immediately ripe. Scaly sit at the inflorescences, bright colored bracts (bracts); they are pink to bluish-red.

The mostly sessile, hermaphrodite flowers are radial symmetry and threefold. The flowers are compressed at the sides. The three sepals are fused at most briefly at their base. The three red, purple, blue to almost black petals are exposed above the ovary. Birds are the pollinators of the blue-flowering species . The petals have two scales (ligula) at their base. There are two circles with three stamens each. The inner stamens are fused with the petals over a large part of their length. Three carpels are at a completely constant ovary grown.

Flower formula :

Low-juice berries are produced.

Systematics and distribution

Charles Gaudichaud-Beaupré established the genus Quesnelia in 1842 in Voyage Autour du Monde ..., Botanique , plate 54. The genus name Quesnelia honors either the French consul in French Guiana , M. Quesnel, who brought the first plant specimens to France, or François Alexandre Quesné (1742-1820). Type species is Quesnelia rufa Gaudich. Synonyms for Quesnelia Gaudich. are: Guesmelia Walp. , Lievena rule .

The distribution area of the genus Quesnelia is limited to eastern Brazil .

There are 18 (Luther 2008) to 23 (as of the end of 2014) Quesnelia types:
Upright inflorescence of Quesnelia arvensis with reddish bracts and bluish flowers
Overhanging inflorescence of Quesnelia humilis
Only in a few species of the Bromeliaceae family are the inflorescences formed laterally and terminally, as in Quesnelia lateralis
Upright inflorescence of Quesnelia testudo with red bracts and bluish flowers

use

Since the inflorescences do not last as long as, for example, Aechmea , these species are rarely found in private collections. But in almost all botanical gardens you can find at least one species of these relatively undemanding but decorative plants.
