## What you would see

A vertical botanical plate on cream, slightly aged paper with irregular, stained edges. In the upper right corner, small printed lettering reads "Tab. XLIII." The composition combines several studies of the same plant as if floating on the empty ground. At upper left, a thin green stem rises diagonally bearing five large, oval leaves with strongly marked parallel veins and a wavy outline; among them are a small white flower with a burst of fine yellow stamens and a tiny budding bloom. Separated at upper right is an enlarged single flower, white with translucent petals and a dense crown of golden filaments. Below, crossing from the right, a bare gray-brown twig forks into reddish stems holding two ripe, pear-shaped yellow fruits with bumpy, mottled skin, clustered above a dense spray of darker green leaves. At mid-left, isolated, is a guava cut in half: its golden rind opens onto granular pinkish flesh and pale seeds, casting a small gray shadow with a few loose seeds beside it. At the bottom, elegant Latin lettering names the plant. The light is even and shadowless except for that one fruit, the colors flat but finely shaded, and the mood is calm, orderly, and inquisitive.

## How to look at it

First follow the flowering stem on the left and then the fruiting branch on the right, and notice how both stages of the plant are shown at once. Then look for the halved fruit: that small scientific cutaway changes the plate from a portrait of a plant into a study of its interior.

## Context

This plate is No. 43, titled "Guaiaba," from Plantae Selectae, published in Germany between 1750 and 1773. The work joined Christoph Jacob Trew, a German physician and botanical patron, with Georg Dionysius Ehret, one of the most noted botanical artists of the 18th century. It is a hand-colored engraving, according to the Cleveland Museum of Art, which holds this impression as a gift of Arnold M. Davis. Such plates combined art and science: they recorded exotic or little-known plants for European readers, describing them in Latin. The exact place and date this specific sheet was printed are not stated beyond the series' publication range.

## Curious detail

Plantae Selectae brought together 100 botanical plates; Ehret, who began as a gardener, became so renowned for his accuracy that the Swedish naturalist Carl Linnaeus was among his patrons and collaborators.

## Questions

- What does showing flower, whole fruit, and cut fruit together tell us that a single view could not?
- How does this 18th-century European image shape the way we imagine a plant native to the Americas?
- Where is the line between scientific document and work of art in a plate like this?
