In Stellaria media , the common chickweed several hairy appendages were seen on the surface of stem and sepals. These were fixed on a slide and observed under foldscope to study their structure.
It was amazing to see that these were glandular trichomes consisting of a stalk that was either unicellular & uniseriate, unicellular and multi-seriate or multicellular & multi-seriate and small in some cases and quite long in others. The stalk supported a knob-like secretory head . The head probably has the ability to secrete some metabolites and aids in defense. Observing several different kinds of trichomes on the same plant was a treat to the eyes.
