INFLORESCENCE MORPHOLOGY IN TALINUM L. (PORTULACACEAE) Closed thyrse instead of solitary flower is worth being considered a floral unit of monotelic synflorescences in both investigated Talinum species. The thyrse is annexing uppermost paracladia and reshaping them into its additional partial florescences (multistages dichasia). Therefore, the thyrse can be uncertainly delimited from the subtending zone of paracladia (T. paniculatum). The whole synflorescence is indistinctly segregated from the plant vegetative body (firstly in T. triangulare), the trait might be typical of any undershrub. As synflorescense and vegetative body are occasionally a bit mingled, the shoot system of investigated Talinum species is to be considered with architectural unit concept while synflorescence morphology and architectural model concept being inappropriate for this purpose either. The architectural unit is recognized to be a shoot of leafy base and terminal bracteate closed thyrse. The unit is either an innovation shoot or a (frondose bracteate) paracladium due to its position on a mother shoot and perhaps environmental influences. It combines occasionally characters of both innovation shoot and paracladium. When an innovation shoots, the units constitute by parts of their bases the perennial axial skeleton of a plant.
