Lymania is a plant genus of the subfamily Bromelioideae within the family Bromeliaceae ( Bromeliaceae ). Eight of the nine Lymania species occur only in the southern Brazilian state of Bahia; a species occurs also to Bolivia.

Description
Appearance and leaves
The Ronnbergia species are epiphytic and terrestrial living, evergreen, perennial herbaceous plants. They make stocks by long thin or short thick spur. A few rough leaves sitting on a compressed stem axis and form slender tubular to funnel where often water is collected. The leaves are bent about half their length inwards, so that the tank acts like a ampoules or bottles like almost closed. The simple, parallel venation, tongue-shaped leaves have spiny -toothed leaf margins. The leaf colors range from blue green to dark green to burgundy. There are shed hairs present.
Inflorescences and flowers
The inflorescence stem is more or less long, so depending on the type of inflorescence slender leaf hopper or not clearly dominates. The bracts are usually inconspicuous. In simple or branched inflorescence eared the flowers are arranged close to very loose spiral ( polystich ). The flowers are on small, triangular bracts, respectively.
The relatively small, pentacyclic ( five petal circles), hermaphroditic, radial symmetry blooms are triple. The three green or red sepals are asymmetrical, 2.5 to 10 mm long and up to half grown together under their length. The three free, usually pure - white to pale - blue petals at their base have no scales ( ligules ). There are two circles, each with three stamens, the stamens are fused to each other free or fused, but always with the petals. The smooth pollen is Porat. Three carpels are fused into one inferior ovary, which is deeply grooved or winged as an important feature of the genus.
The flowers formula is:
Fruits
The typically deeply furrowed, almost spherical berries contain numerous seeds. In the Lymania alvimii when ripe dark - blue berries are on a coral inflorescence axis.
System
The genus Lymania was only in 1984 by Robert William Read in The "evolution" of a new genus. Lymania Gen. nov., Journal of the Bromeliad Society, 34, pp. 199-201 and 212-216 with the type species Lymania alvimii ( LBSm. & Read ) Read erected. The botanical genus name honors Lymania Lyman Bradford Smith, who has the systematics of the family of Bromeliaceae in the 20th century significantly affected; in Erstveröffentlichungsjahr was his 80th birthday.
Robert William Read presented to the genus Lymania to there all kinds with deeply furrowed or winged ovary (but also in Aechmea carvalhoi so ) subg from the taxa Aechmea. Lamprococcus, Araeococcus and Ronnbergia merge. New species were described by Leme, 1987, 2006, and Leme & Forzza 2001. A first revision was carried out by De Sousa 2004 Lymania is the first genus of Bromelioideae in which a complete analysis of the morpholischen characteristics and chloroplast DNA regions. MatK, psbA - trnH and trnL - trnF was performed. Lymania is closest to the Aechmea subg - subgenera of Aechmea. Lamprococcus and Aechmea subg. Ortigiesia related. Lymania is monophyletic in its current size and scope of current knowledge, while Aechmea this is not safe in their present size.
There are about nine Lymania types:
- Lymania alvimii ( L.B.Smith & R.W.Read ) R.W.Read
- Lymania azurea Leme
- Lymania brachycaulis ( E.Morren ex Baker ) L.O.F. de Sousa
- Lymania corallina ( Brongniart ex Beer) R.W.Read
- Lymania globosa Leme
- Lymania languida Leme
- Lymania marantoides ( L.B.Smith ) R.W.Read
- Lymania smithii RWRead: It comes from Brazil to Bolivia before.
- Lymania spiculata Leme & Forzza
