A Plant Specimen Is a Compressed Landscape

Reading a herbarium sheet and an Anna Atkins cyanotype reveals what scientific images preserve and what they leave out.

A pressed plant is a landscape that has been made thin enough to file. Its roots no longer enter soil. Its leaves no longer turn towards the light. The plant has become available to the eye in a way that the living thing never was.

Look at a herbarium sheet as an arrangement. A stem travels across the paper. Leaves are spread so that some of their surfaces can be inspected. A label occupies another area, adding words to the flattened body. It is possible to enjoy this arrangement before knowing what the plant is, but the pleasure becomes more interesting when you ask why it has this shape.

Kew describes herbarium specimens as plants preserved through drying and pressing or in fluid, with digital records combining specimen images and information from collection labels. [1] These are working records. Their visual qualities emerge from the effort to make a particular piece of life identifiable and available for later study.
