Description
Appearance and leaf
The funnel - or Zisternenbromelie Aechmea aquilega is an evergreen, perennial, herbaceous plant. It grows mostly terrestrial or sometimes as an epiphyte and Lithophyt. It has funnel diameter of up to 300 cm and plant height of up to 100 cm. The bright green, tough, 100 to 150 cm long leaves are on the edge reinforced (as with all representatives of the Bromelioideae ). The 5 to 10 cm wide leaf blade is oblong and rounded at the top, but with a long spike tip. In the leaf hoppers often collect large amounts of water. The leaves have on the top and bottom whitish Saugschuppen ( trichomes ).
Inflorescence, flower and fruit
The upright, scaly, thick inflorescence stem has a length of 60 to 100 cm. The up to 40 cm long, handsome, long-lasting, branched, racemose total inflorescence ( inflorescence ) is from short-stalked, 15-20 cm long, aged men part inflorescences, each with several bündelig together standing flowers composed. At the inflorescences sit conspicuous reddish, oblong- lanceolate bracts ( bracts ), which have a smooth edge and a stachelspitziges upper end. The bare, yellow to greenish bracts are much larger than the ovary and much shorter than the sepals, broadly ovate, keeled and mucronate end.
The sessile, hermaphrodite flowers are triple double perianth. The three asymmetric, 1.4 cm long sepals are fused into a short tube, and ovate - lanceolate calyx lobes are at the upper end mucronate. The three spatulate petals are fused into a short tube. Two small flakes to the petals ( ligules ) form a characteristic that botanists use to distinguish it from other genera of the subfamily. The color of the petals are yellow. There are two circles, each with three stamens present. Three carpels are fused into one inferior ovary.
The flowers formula is:.
Are formed berries.
Occurrence
Aechmea aquilega is widely used in Costa Rica, Venezuela, the Guyanas, Brazil, and on Trinidad and Tobago. It grows at altitudes 0-650 meters.
System
The first description was in 1806 under the name ( basionym ) Bromelia aquilega by Richard Anthony Salisbury in The Paradisus Londinensis, panel 40 The recombination to Aechmea aquilega ( Salisb. ) Griseb. 1864 August Heinrich Rudolf Grisebach: published Flora of the British West Indian Islands, p 592. On the type material we find the words: "Type:" Jamaica Other synonyms for Aechmea aquilega are " D. Hurlock sn, no specimen preserved, typified by the original plate.

Aechmea aquilega belongs to the subgenus in the genus Aechmea Aechmea.
There are two forms of Aechmea aquilega:
- Aechmea aquilega var aquilega f alba Oliva - Esteve: It is native only in the state of Carabobo in Venezuela.
- Aechmea aquilega ( Salisb. ) Griseb. var f aquilega aquilega: It occurs in the overall range of the species.
Sometimes found in the literature is a variety Aechmea aquilega var chrysocoma ( Baker) LBSm, but for example in JAS Filho & Elton MC Leme. Fragments of the Atlantic Forest of Northeast Brazil - Biodiversity, Conservation and the Bromeliads, 2007 has rank one type Aechmea chrysocoma Baker.
Aechmea aquilega is involved in several horticultural hybrids produced:
- Aechmea ' Exotica Mystique ': Mother is Aechmea lueddemanniana
- Aechmea ' Isabel D' Bellard ': Mother is Aechmea rubens
- Aechmea ' Tropica ': Father is Aechmea rubens
- × Portemea ' Phat Pat': This genus hybrids were bred in 1996. Mother and father Portea leptantha Aechmea aquilega.
