Leucas lavandulifolia, again. The calyx here is characteristically very oblique at apex, 8-toothed; teeth irregular/minute and the posterior teeth is the largest.
In L. aspera, the calyx is slightly oblique at apex, 10-toothed; teeth unequal but not as above.
Of course there are several other differences such as: hairs on the stems are deflexed in the former and they are spreading in the latter species.
