Brewcaria

Brewcaria is a plant genus in the subfamily Navioideae within the family Bromeliaceae ( Bromeliaceae ). Previously they were classified in the subfamily Pitcairnioideae. The genus name honors Brewcaria the Venezuelan explorer and naturalist Charles Brewer Carias - (* 1938). Today Allow about six species in this genus. Distribution area is the Guiana highlands in the north-eastern South America, only in the states of Colombia and Venezuela. There is no known use by humans, and even botanical gardens rarely have copies in their collections.

Description

In Brewcaria species are terrestrial or lithophytische, somewhat xerophytic perennial herbaceous plants that can sometimes form by vegetative propagation stocks.

In basal rosettes the tough, stiff leaves are together. The leaf margins are cut prickly. At least the lower leaf surface is scaly.

Brewcaria species form a more or less long, erect inflorescence stem. The always easy, aged men, dense inflorescences have bracts. There are never flower stems available. The hermaphrodite flowers are triple. The three sepals are not keeled. The three free petals have two transverse, horizontal advertised scales ( ligules ); Main difference to the closely related Navia who do not have ligules and the Steyerbromlia whose ligules are inserted vertically. There are two circles, each with three equal, free stamens present. Three carpels are fused into a semi- inferior ovary. The style ends in three narrow scars branches.

The flowers formula is: or

Are formed capsule fruits. The seeds are most very narrow winged.

They have the type of C3 plant photosynthesis.

System

The genus Brewcaria in 1984 by Lyman B. Smith, Julian Alfred Steyermark & Harold E. Robinson in Acta Botanica Venezuelica, 14 ( 3) set up with only two newly described species. Type species is Brewcaria duidensis LBSm. , Steyerm. & H. Rob.

Since molecular genetic studies showed that the subfamily Pitcairnioideae was not monophyletic in their original extent it was divided into several subfamilies. The subfamily Navioideae was reactivated with the genera Navia, Cottendorfia, Sequencia, Steyerbromelia and Brewcaria. Of the genus Navia 1997, the species with aged men or paniculate inflorescences in the genus and the species Brewcaria with appendages were spun at the seeds in the genus Steyerbromelia by Bruce K. Holst. This four other species came to the genus Brewcaria that were previously all of Lyman B. Smith described as Navia species.

There are six types of Brewcaria:

  • Brewcaria brocchinioides ( LBSm. ) B. Holst ( Syn: Navia brocchinioides LBSm. ): It comes at altitudes of 300 to 400 meters in front of the Venezuelan state of Amazonas.
  • Brewcaria duidensis LBSm, Steyermark & H.Rob: .. Thrives terrestrial or lithophytic on the marshy Gifelplateu the Tepui Cerro Duida at altitudes of about 1500 meters in the Venezuelan state of Amazonas.
  • Brewcaria hechtioides ( LBSm. ) B.Holst ( Syn: Navia hechtioides LBSm. ): It grows terrestrially in the savannas of the Venezuelan state of Amazonas.
  • Brewcaria hohenbergioides ( LBSm. ) B.Holst ( Syn: Navia hohenbergioides LBSm. ): It grows terrestrially on slopes and in the savannas at altitudes between 200 and 600 meters in the Venezuelan state of Amazonas.
  • Brewcaria marahuacae LBSm, Steyermark & H.Rob: .. It is resident in the Venezuelan state of Amazonas.
  • Brewcaria reflexa ( LBSm. ) B.Holst ( Syn: Navia reflexa LBSm, Navia gracilis LBSm. . ): It grows at altitudes between 100 and 200 meters in Colombia and Venezuela.
