Abstract
Five new species of Dionysia are described (D.
viva, D. zschummelii, D. crista-galli, D. zetterlundii
and D. tacamahaca) from the Zagros mountains of W
Iran. One subspecies (D. sarvestanica subsp. spatulata),
one variety (D. gaubae var. macrantha) and two
sections (D. sect. Zoroasteranthos and D.
sect. Mucida) are also described as new. A revised
classification of the genus is suggested and a complete list
of species is provided, in which some emendations to
previously published data are given. A dichotomous key to
the species is presented.
