The lance rose ( Aechmea fasciata ) is a species of the genus Aechmea in the subfamily Bromelioideae within the family Bromeliaceae ( Bromeliaceae ). The specific epithet means fasciata banded and refers to the drawing of the leaves. The Greek word means aechme spearhead and so it comes to German trivial name Lanz rosette. Another seldom -used common name is silver vase and refers to the silvery -acting leaf hopper. It is one of the commonly cultivated as house plants types of Bromeliaceae. There are some varieties. The home of this type is Brazil, especially in Bahia, Rio de Janeiro and Guanabara at altitude 700-1300 meters.

Description

The funnel - or Aechmea fasciata Zisternenbromelie is an evergreen, perennial, herbaceous plant. They have funnel diameter of 50 cm and plant height of 35 to 50 cm. It grows as an epiphyte. The tough, up to 50 cm long leaves are on the edge reinforced (as with all representatives of the Bromelioideae ). The leaf sheath is 9 to 10 inches wide. The 6 cm wide leaf blade is rounded at the end, but with a 4 -mm-long spike tip. In the leaf hoppers often collect large amounts of water. In the natural habitat there is in many of the funnel small biotopes with several animal species as well as algae and aquatic plants. The leaves have on the top and bottom whitish Saugschuppen ( trichomes ); they are distributed differently depending on the variety: you can cover the entire surface or with and without scales available transverse bands, this leads to an interesting leaf markings. There are also varieties with yellowish longitudinal lines ( variegation ).

The inflorescence stem has a diameter of 1 cm and a length of 30 to 40 cm. The range of attractive, long-lasting, branched at the base and simple at the top, capitate - pyramidal total inflorescences ( inflorescences ) are composed of aged men part inflorescences. Sitting at the inflorescences striking pink bracts ( bracts ) that have a prickly toothed margins.

The sessile, hermaphrodite, threefold flowers have a length of about 3.5 cm. The three asymmetric, 1 cm long sepals are fused to a short (2.5 mm) tube; they are pink, white - woolly scaly and dull at the end. The three 3 cm long 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 initially blue, wilting they turn up red and white against the base. There are two circles, each with three stamens present. Three carpels are fused into one inferior ovary, which has a diameter of 5 to 6 mm and a length of 6 to 8 mm.

The flowers formula is:.

Use

The lance rose ( Aechmea fasciata ) is a very long flowering, very easy to care houseplant that is produced in larger quantities., There are several varieties and also hybrids with other Aechmea species. The variety ' Primera ' the company Bak ( in Rijsenhout, Netherlands ) is a sterile hybrid and has smooth leaf margins.

The increase in the hobby gardener and variegated varieties is done by Kindel. In horticulture, the propagation by seed or vegetable tissue culture is done. To speed up the culture and to control the time of sale, acetylene can be initiated from gas bottles to funnel water for flower induction.

In cultivation in monocultures, it is very susceptible to leading to a wilt disease fungus of the genus Fusarium.

System

This species was by John Lindley as Billbergia fasciata Lindl. Lindl. 1828 ( Botanical Register, 13) first described. John Gilbert Baker realized that she belongs to the genus Aechmea and published in 1879 ( in Journal of Botany 17, 231) Aechmea fasciata the name. L.B. Smith and W. J. Kress in 1989, these and other species in a new genus Platyaechmea outsourced ( New or restored genera of Bromeliaceae in Phytologia 66, pp. 70-79 ): Platyaechmea fasciata ( Lindl. ) LBSm. & WJKress, this view has, however, not enforced. Other synonyms are: Aechmea hamata Mez, Aechmea leopoldii Baker, Aechmea rhodocyanea ( Lem. ) Wawra ex Mez, Billbergia glazioviana rule Billbergia rhodocyanea Lem, Quesnelia rhodocyanea Wawra ex Mez, Hohenbergia fasciata ( Lindl. ) Schult.. & Schult.f. , Hoplophytum fasciatum ( Lindl. ) Beer, Tillandsia bracteata Vell.

There are four varieties of Aechmea fasciata:

• Aechmea fasciata ( Lindl. ) Baker var fasciata
• Aechmea fasciata var flavivittata Reitz ( Syn: Platyaechmea fasciata var flavivittata ( Reitz ) LBSm & WJKress. )
• Aechmea fasciata var pruinosa Reitz ( Syn: Platyaechmea fasciata var pruinosa ( Reitz ) LBSm & WJKress. )
• Aechmea fasciata var purpurea ( Guillon ) Mez ( Syn: Billbergia rhodocyanea var purpurea Guillon, Platyaechmea fasciata var purpurea ( Guillon ) LBSm & WJKress. )
