All species of plants from which controlled substances in Schedules I and II may be derived which have been planted or cultivated in violation of this chapter, or of which the owners or cultivators are unknown, or which are wild growths, may be seized and summarily forfeited to the state. The failure, upon demand by the chief agent or any peace officer at his direction, of the person in occupancy or in control of land or premises upon which such species of plants are growing or being stored, to produce an appropriate registration, or proof that he is the holder thereof, shall constitute authority for the seizure and forfeiture.
