Abstract

First records of four alien plant species for the flora of Tajikistan are presented: Amaranthus powellii S. Watson (Amaranthaceae), Erythranthe guttata (DC.) G. L. Nesom (Phrymaceae), Medicago lessingii Fisch. et C. A. Mey. ex Kar. (Fabaceae), and Solidago gigantea Aiton (Asteraceae). Of these, Erythranthe guttata and Solidago gigantea present novelties to the flora of the whole Middle Asia. For each species, its distribution and habitat, as well as taxonomic notes, are presented. In addition, chromosome numbers (CHNs, 2n) from the new localities are given for the first three species.


Key words: Amaranthus powellii, Erythranthe guttata, Medicago lessingii, Solidago gigantea, Po­well’s amaranth, seep monkeyflower, Lessing’s medick, giant goldenrod, Tajikistan, floristic novelties, chorology, taxonomy


Section: Floristic records
