Sample obtained from 1115-1147 E California Blvd, Pasadena, CA 91125 Next to Linde at Caltech at 6:30 PM 5/6/19.
Sample was obtained from a bush with flowers. The pollen was wiped onto a slide and a cover slip was used to hold in place. Questions: why is the pollen shaped like triangles? what plant species is this from? These questions can be answered with a quick google search and asking the gardener/maintenance #caltechbi1
Triangular particles can be seen, indication pollen.
