Cymes usually with bracts at base, otherwise ebracteate, elongating greatly after flowering. Pedicels becoming 1-3× length of calyx at fruiting. Calyx 1.5-3 mm long at anthesis, clothed in straight appressed hairs; teeth c. 1/2 length of tube at anthesis, to c. 4 mm long at fruiting, triangular-ovate, subacute to acute.
