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

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. _________________ Graham |
