The paper demonstrates S. dulcamara ecobiomorphs: a long rhizome semi-woody liana (LSL), a long rhizome subshrub with ascending shoots (LSAS), a root sucker subshrub and a shortlived plants of vegetative origin; and ontobiomorphs: a taproot upright subshrub (TUS), a subshrub with a mixed root system (SMRS), LSL, and LSAS. Possible stages and modes are suggested of Solanum biomorph transformation: 1. TUS, as a result of prolongation on the shoot (adventitious roots) and shoot system level (two or more replacement shoots), deviations on individual plant level (shoot lodging), transforms into SMRS; 2. SMRS, through the plant’s ontogenesis abbreviation (fragmentation), prolongation (epigeogenum rhizome), and deviation (stem twisting), transforms into LSL. Further LSL habit transformations can occur in xerophylous and hygrophylous biomorph evolution lines. On dry soil, as a result of prolongation (adventitious buds on roots), a root sucker subshrub appears. A hygrophyle line is possible in case of prolongations on the shoot level (metamere number increase within a shoot, dicyclic shoots), of the individual plant abbreviations (shortened life-time of sympodial axes, early fragmentation) and end with a short-lived plants of vegetative origin. Possibly, mien changes in S. dulcamara ontogenesis show possible stages in Solanum life forms transformation, from tree forms to LSL.
