What is "adamantinia"

Adamantinia is a monotypic genus of orchids ( family Orchidaceae), described in 2004 by Cássio van den Berg and Cezar Neubert Gonçalves. The name is a reference to Chapada Diamantina, Brazil, where this species comes from.

The single species, Adamantinia miltonioides, is native to the Serra do Sincorá range ( Brazil, Bahia, South America). It grows as an epiphyte at sunny positions, at about 900m altitude. Plants bear more or less clustered unifoliate pseudobulbs (rarely bifoliate), coriaceous dark-olive leaves, and possess long inflorescences with successive flowering. Flowers are showy, pink, with similar petals and sepals and a showy dark pink lip, with very small side lobes. Column is short, with a broad stigma. DNA data from trnL-F plastid sequences indicate relationships to Leptotes and Isabelia.
