The present paper deals with phytosociological and pedological investigations in natural as well as antropogenous forestes of the Molineo Pinetum from Swiss Midlans.The autor results having been compared with the previous data,the following classification of the Molineo-Pinetum is suggested:a)subassociation with 1)Epitacis palustris -variant 2)Listera ovata-variant 3)Genista tinctoria -variant 4)Sanguisorba minor-variant b)Subassociation with Laserpitium latifolium 5)typical variant 6)Geranium sanguineum -variant 7)Parnassia palustris - variant. The variants described under 1-3 represent open forests with well developed herb layer containing numerous Gramiae and Cyparaceae.The variants no.4 cannot be fully compared to them, for a diferrent method has been usedfor the resp.releves.The variantes No.5-7 are natural forestes occurring on steep slopes of northwestern Swiss Midlands;the variant No.6 appears on drier soils than the typical variant,but its exposure is most the same, 1.e.southern or western .The variant No.7 occours on N-exposed steep slopes within the ridge of Albis,in sites that are permanently wet due speeping soil water.All the studied variants are caracterizred by the absence of Fagus silvatica in the tree layer, in spite of the fact that the beech represents the climax forest species of colineand submontane zone within the studied area.The present investigations show that the Molinia-Pinus forests inhabit the marly rendzina thatis youger and shalower than soils of the neighboring forests of Fagus.Marly rendzina developes very slowli;its uppermost layer may sometimes be removed by lands lides wicht results in recurrent successions. Fagussilvatica is able to germinate in the Molineo Pinetum, its life span beeing about 30 years; however,only exceptionally grow the individuals taller than 50cm and so they nearly always remain within the herb layer.The abnomarly reduced growth is apparently caused by propeties of the marl soil that may remain quite wet for some time,but rapidly manifests srongs water deficiency in dry periods.The shallowness of marly rendizina as well as the above mentioned qualities of the marl may accordingly be considered as principal factors responsible for the absence ofFagus silvatica in the Molinea Pinus forestes occurring within the climax zone of this especies.
