THE GENUSLAGOCHITUS (LABIATAE) II{ Z.lamzad

Jamzad, 2.L988. 12 . 31'j[he. genus Lagochilus (Labiatae) in Iran. - Iran. Journ. Bot. 4 (1): 91 - 103. .

A revision of the genus Lagochilus (Labiatae) in Iran is presented. Altogether 6 species are recognized from lran. A new species, L. quadridentatus and 3 new subspecific taxa including L. aucheri subsp. heterophyllus, L. aucheri subsp. aucheri var.elegans andI. aucheri subsp. aucheri var. tomentosrrs are described. L, lasiocalyx is the new combination, based on L. aucheri vax. lasiocalyx. L. ar,rcheri vat. perhispidus is treated as a synonym of L.lasiocalyx.
