Jungius was the first to appreciate and expand upon the botanical ideas of Cesalpino. In this posthumously published work, edited by his student Martin Fogel, and in his  Isagoge phytoscopica published in 1669, Jungius gave a remarkable account of plant morphology, analyzing plants into a limited number of fundamental parts, and describing these and their relations ton one another with precise and comprehensive terminology. Jungius's methods of morphological analysis were adopted by John Ray and Linnaeus.
