Augustini-Pyrami Decandolle, Astragalogia, nempe astragali biserrulae et oxytropidis, nec non phacae, colutae et lessertiae, historia iconibus illustrata
A Latin botanical monograph by Augustin Pyramus de Candolle, published in Paris in 1802 by Garnery and printed by Didot Junior, treating the milkvetch genus Astragalus and related legume genera for botanists. Its engraved plates show pinnate leaves and flowering stems drawn in fine graphite-like shading on cream paper, offering designers a model for rendering botanical structure with delicate hatched tones and clean outlines.
