	abstract = {The sixth contribution to the flora of Zurich deals with 104 genera and 17 families among others Umbelliferae, Boraginaceae and Labiatae. Of the 222 species studied, 155 are or were more or less established in the region. 26 (17 \%) of these species disappeared, 49 (31 \%) decreased in frequency, 25 (16 \%) colonized newly various areas of the region and 8 (5 \%) are more frequent today. 43 (18 \%) species show about the same distribution and frequency today as 160 years ago.The remaining 4 species were possibly overlooked by Kolliker(1839). The following critical groups were analyzed more closely: Aethusa cynapium s. l., Pastinaca sativa a. l., Monotropa hypopitys s. l., Primula vulgaris-elatior-veris, Myosotis palustris s. l., Ajuga reptans-genevensis, Galeopsis tetrahit s. l., Lamium galeobdolon s. l., Thymus serpyllum s. l., and Mentha.},
