The reddish brown glochids of Opuntia violaceae are very loosely attached and fly off when the plant is handle. The loose glochids are an irritant, and can get under clothing, in eyes, and may even be a breathing hazard. For safe handling, wet specimens before moving. The water weighs down the glochids, preventing them from becoming airborne.
