Pl help me to arrive at identification of the attached Blepharis sp.
Observed in Tisaiyanvilai, Tirunelveli Dist of Tamilnadu.
Heads mostly 1-fld. many of the outer bracts barren, bracteoles elliptic or oblong sub-sessile, petals blue in colour.
It suits the description of B molluginifolia, which is a synm of B integrifolia as per the plant list.
Whether it could be Blepharis integrifolia var. clarkei (Schinz) Oberm
