He is in particular the author of:

Das mechanische prinzip in anatomy Beam der Monokotylen (1874).
Die mechanische Theory der Blattstellung (1878).
Über Beam und Mechanik der Spaltöffnungen (1881).
Gesammelte botanische Abhandlung (1898).

Schwendener studies the histology of the Lichen S and shows that they are made of a Champignon and of a Algue in 1868. Hitherto, the specialists classified the lichens in a special category, placed between mushrooms and the plants. For Schwendener, the mushroom would live in parasite with the detriment of the alga. The discovery of Schwendener is done into same as the observations of Heinrich Anton de Bary (1831-1888). In the years which follow, double nature will be shown by other specialists, of which the Russians Josep Wasilijewitsch Baranetzky (1843-1905) and Andrei Sergeevich Famintsyn (1835-1921). But the vision of the quasi-state of slavery of the alga by mushroom is disputed by certain as Johannes Reinke (1849-1931) which prefers the concept of consortium.
