The female cannabis plant has a corolla but not well defined. It makes up part of the perianth, in more showy flowers this part would typically be the petals, but cannabis never evolved such features since it is wind pollinated and does not rely on pollinators. The corolla and calyx of cannabis plants are not as defined, but make up the perianth which is located inside the bract, around the ovule.
