Commentary

Narrow endemic species probably which is not leaving for limits of pool of the river Schachimardan. The form of tepals unusual, Lloydious of a type. The developing bulblet changes colouring from white, through pale pink, beet up to is black - brown. The second basal leaf is reduced. The species is strongly neotenycal.
