Fascicularia bicolor is the only species of the genus Fascicularia in the subfamily Bromelioideae withinthe bromeliad family (Bromeliaceae).
The genus name Fascicularia is derived from the Latin word fasciculus for bundle, bundled and refers to the shape of the inflorescence, i.e. the crowded arrangement of the flowers; bicolor means two-colored.
description
Fascicularia bicolor is a stemless perennial herbaceous plant . This xerophyte usually grows terrestrially, on rocks or as an epiphyte . With their foothills, they often form dense stands. The numerous, basal, long leaves are thin, elongated, coarse and strongly reinforced at the edge (prickly sawn).
The simple, ährigen , head-shaped inflorescences sit with a very short inflorescence stem striking red colored bracts (bracts). An inflorescence contains many flowers. The three-fold, radially symmetrical flowers are hermaphroditic with double perianth . The three sepals are free and can still be seen on the ripe berries. The three free petals are blue to purple, with two scales (ligules) at their base. There are two circles with three free stamens each. Three carpels have become an under constant ovary grown. The stylus ends in a three-lobed scar. Style and stamens are shorter than the petals.
The berries still have the sepals and contain many seeds.
Occurrence and systematics
The distribution area of Fascicularia bicolor is only in Chile . It occurs at altitudes between 100 and 1250 meters.
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 , Fascicularia parviflora Mez , Fascicularia micrantha (Phil.) Mez ): The flowers are 3.7 to 6.5 (rarely up to 7.5) cm long. The distribution area extends from the Región de Valparaíso (San Antonio) to the Región de los Lagos (Chiloé), i.e. Region V to X.
- Fascicularia bicolor subsp. canaliculata E.C. Nelson & 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 xeromorphic than in Fascicularia bicolor susp. Bicolor . The flowers are 3.3 to 4.4 cm long. The distribution area extends from the Región del Maule to Chiloé in the Región de Los Lagos, i.e. Region VII to X.
Due to their size, Fascicularia bicolor is rarely found in private collections, but in many botanical gardens.
There is often 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).
