Infraspecific variability in Asystasia dalzelliana Santapau from southern Western Ghats of Kerala - An overview

During field expeditions, Asystasia dalzelliana specimens were collected from different geographical locations from the state of Kerala. The collected populations varied with respect to the color and size of the flowers. Subsequently, critical evaluation has been done using qualitative and quantitative traits. The DL3 and DL4 types were found to have restricted distribution patterns. The affinities among the collected specimens have been interpreted through two-dimensional scatter plot and PCA which proves that the variations are solely restricted in the flower color and banding of anthers. The study resolves the ambiguity among the color variants of A.dalzelliana.
