Pistia Stratiotes had a fine glass fibre gummed on so as be able to read the angle either by Abney Level or Protractor & plumbet

Angles not read very exactly

Mimosa ‒ fine glass fibres tipped with sealing wax gummed to 2 middle secondary petioles (just projectg beyond leaves). Main petiole fixed onto a bit of cork; protractor lies horizontally under the leaf with its centre under the junction of the 2ndy petioles
