Fascicularia bicolor

Inflorescence of Fascicularia bicolor.

Fascicularia bicolor is the only species of the genus in the subfamily Fascicularia Bromelioideae within the family Bromeliaceae ( Bromeliaceae ).

The genus name is derived from Fascicularia from the Latin word for fasciculus bundle, bundled, and refers to the shape of the inflorescence, so the crowded arrangement of the flowers; bicolor means two colors.

Description

Fascicularia bicolor is a stemless perennial, herbaceous plant. This usually grows xerophyte terrestrial, to rocks or as an epiphyte. With its foothills they often form dense populations. The numerous undergraduate, long leaves are thin, oblong, dense and strongly reinforced at the edge ( spiky cut ).

An easy, aged men, head-shaped inflorescences with very short inflorescence stem sit conspicuous red colored bracts ( bracts ). An inflorescence contains many flowers. The threefold, radial symmetry flowers are hermaphrodite with double perianth. The three sepals are free and can still be seen well on the ripe berries. The three free petals are blue to purple, with two scales ( ligules ) at its base. There are two circles, each with three free stamens present. Three carpels are fused into one inferior ovary. The style ends in a three-lobed stigma. Style and stamens are shorter than the petals.

Flowers formula:

The berries do not have the sepals and contain many seeds.

Occurrence and systematics

The distribution area of Fascicularia bicolor is only in Chile. It occurs at altitudes 100-1250 m.

There are two subspecies:

  • Fascicularia bicolor subsp. bicolor Nelson & Zizka ( syn.. Bromelia joinvillei E.Morren, Rhodostachys joinvillei ( E.Morren ) Benth, Rhodostachys micrantha Phil, Fascicularia bicolor ( Ruiz et Pav ) Mez, Mez Fascicularia parviflora, Fascicularia micrantha ( Phil.) Mez ): The flowers are 3.7 to 6.5 (rarely to 7.5) cm long. The range extends from Región de Valparaíso ( San Antonio ) to the Región de los Lagos ( Chiloé ), ie Region V to X.
  • Fascicularia bicolor subsp. canaliculata ECNelson & Zizka ( Syn: Hechtia joinvillei Riviere, Rhodostachys albo- bracteata ( Steud. ex Baker ) Baker, Rhodostachys pitcairniifolia var kirchhoffiana Wittm, Fascicularia kirchhoffiana ( Wittm. ) Mez. ): The leaves are less than Xeromorph F. b. bicolor subsp. The flowers are 3,3 to 4.4 cubic long. The range extends from the Maule Region to Chiloé in the Región de Los Lagos, ie Region VII to X.

Because of their size can be found Fascicularia bicolor rare in private collections, but in many botanical gardens.

Often there is confusion with the species of the closely related genera Ochagavia ( In Ochagavia the petals are pink and there are no two scales at their base. ) And Greigia ( In Greigia the petals are white to pink to reddish color ).
