    Hartmann (Bot. Jahrb. 85:341.1966) records " Lappula redowskii var. eu-redowskii” from Braldo vy., C. Karakorum, but I have not been able to verify this record.

    A variable species throughout its geographical range in flower colour, leaf shape, peduncle length and fruit characters. Our plants generally are blue-flowered with a single row of marginal appendages. M. Popov (l.c.) has aptly summed up the species variability. Found in semi-desert and dry montainous areas up to 3600 m.
