This is a transverse section of a stem in polarised light.

It is an old slide. The handwritten label looks like Sequiselum spp.

Projectina microscope
Objective: Watson x4 parachromat

This is almost certainly a cross-section of Equisetum, the common horsetail. This plant is a favorite of those beginning microtechnique because it stands up so well to sectioning despite its ornate arrangement of vascular bundles.

- yes I had it in the back of my mind that it was a horsetail, but never cross-checked the species name with the handwriting on the slide.

Thanks, Garry.
