Common name: None known. Latin name and synonyms:
Lehmanniella Gilg (1895)
Etymology:
Lehmanniella was probably named after Karl [Carl] Friedrich Lehmann
(1850–1903). Lehmann was the German consul in Popayán, Colombia, and he
was also an avid collector of plants both in Colombia and Ecuador. He
drowned when crossing a river in South America and it is uncertain if it
was an accident or if he got murdered. Most of his collections were in the
Berlin herbarium where Ernst Gilg worked. (During WWII most of the
collections of the Berlin herbarium was destroyed.)
Species: Two
species only.
Distribution:
High elevation areas in mountains, one species in Colombia and
the other in Peru.
Habitat:
Cloud forests.
Characteristics:
Herbaceous or slightly woody
plants, with scandent branches. Leaves ovate to elliptic leave.
Inflorescence terminal umbels, few-flowered.
Flowers
5-merous. Calyx campanulate; lobes elliptic, rounded at apex. Corolla
narrow, red, tubular, inflated; lobes short and rounded. Stamens inserted
near base of corolla tube; anthers sagittate, with small
sterile apical appendage. Gynoecium with glandular disk; style long;
stigma with narrow lobes. Fruit a woody capsule.
Evolution
and related plants:
Lehmanniella is most likely closely related to Lagenanthus
and Purdieanthus in tribe Helieae, but no phylogenetic data is
available.
Economic
uses: None known.
Notes: Lehmanniella
included Lagenanthus and Purdieanthus in some treatments.
