He attended classes in medicine and botany at the University of Halle, afterwards continuing his studies in Göttingen, where he was a pupil of botanist Heinrich Adolf Schrader (1767-1836). In 1816 he obtained his medical doctorate at the University of Göttingen. In 1822, he was appointed district physician to the city of Nordhausen, where along with his duties as a doctor, he performed botanical research.[2]

Among his writings were a treatise on cryptogams native to Germany, Flora Cryptogamica Germaniae (1831–33), and a study on the biology of lichens, titled Naturgeschichte der Flechten (1825 and 1827). Wallroth is credited for introducing the terms "homoiomerous" and "heteromerous" to explain two distinct forms of lichen thallus,[3][4] as well as the terms "epiphloeodal", "hypophloeodal", and gonidium.[5] Wallroth retired in 1855; he died two years later. His extensive herbarium was sold in several separate parts after his death. A large part went, together with some written materials, to the National Museum in Prague.[6]
