L. in Iran comprises of 18 medicinal and/or ornamental plant species. Iranian species of this genus are traditionally classified in four subgenera and the taxonomy of the genus has been controversial. F. ariana
, F. bucharica
and F. gibbosa
were transferred by some taxonomists to a new established genus (Rhinopetalum
) and new taxa are introduced within existing subgenera. F. crassifolia
has been promoted as F. kurdica
and later was rejected. Fritillaria poluninii
was also another controversial taxon which was promoted from F. crassifolia
and later was rejected. F. crassifolia
is an interesting and morphologically variable species growing in NW Iran. F. grossheimiana
was established by Los- Losinsk.
From specimens collected from Tabriz (NW Iran) and later was rejected and identified as F. crassifolia
. Circumscription of the species using morphological characters is flawed and more precise sources of characters are needed. Molecular phylogeny of the genus is not fully studied and the current data do not encompass the important intra-specific variations.
This study was aimed to evaluate the applicability of flavonoids spot profiles in taxonomic circumscription of Fritillaria
L. species in Iran. Sixty two samples from eight species of the genus Fritillaria
collected from natural plant populations across Zagros Mountains chain of Iran are studied. Results based on flavonoids spot profiles revealed the patterns of inter- and intra-specific variations. Flavonoids spot profiles were both able to separate species and show intra-specific variations, confirming the applicability of flavonoids for chemotaxonomy of the genus. Qualitative data (0/1) are analysed using multivariate techniques and detailed results are presented as clustering and ordination graphs.
