    Yes, this is correct. Glochids, which function to defend the plant, can grow on types of cacti like the prickly pear and cholla. They often grow in clusters, and may appear to be white fuzzy  material or sharp spikes. Touching glochids can make the affected skin painful and sensitive as well as bother the eyes. If ingested, the glochids don’t have very toxic effects, though they can cause more severe problems for diabetics. Additionally, glochids are sometimes blown away by the wind, becoming an irritant in the air.
