To make seed photos more useful, it would be very informative if a ruler, scaled in millimeters and inches, could be included in the photo.

done

opps, no ruler; next time...

Another way to provide scale is to photograph the seeds on a background of graph paper, although then the grid size of the graph paper has to be explained in the photo caption or somewhere else.

The pen for scale work for me in this shot!

Highly invasive in Australia; a declared pest in Western Australia. It is a good example of thigmonasty or seismonasty.

@Gleni, that would be a good comment to add to the database entry itself rather than this seed picture thread. Just click on Sensitive Plant (Mimosa pudica) above jmorth's image, and under the Adding Actions on the left side, you'll see 'Post a comment'.

Oh, I thought I had placed it right this time.

Edit. I had another go. I think that I might have done it right now Sue. See what you think.

Perfect!!

With a pen for scale, it would be pretty dicey to distinguish seeds that are 2-4mm in diameter, from a similar species whose seeds that are differentiated by being 4-6mm, wouldn't it?

That particular shot works for me, personally. It's not comparing different seed sizes. And I don't know the difference between
2-4 & 4-6mm anyway, sorry. Not a measurement I ever use.

After my silly post above, yes, I agree with your original post, using a ruler sure is helpful for visually sizing seed shots.
