Summary Nieto Feliner, G.: Growth‐form and taxonomy in Arenaria sect. Plinthine (Caryophyllaceae). – Taxon 43: 45‐50. 1994. – ISSN 0040‐0262. A study of the growth‐forms in Arenaria sect. Plinthine is presented, describing and interpreting two different, systematically relevant, patterns that are defined by the position of the innovation buds. The first, apparently the more evolved one, probably constitutes a good synapomorphy for the 7 taxa exhibiting it: innovation buds arise on short, vegetative lateral shoots arising below the starting point of the season's growth of the fertile axis. In the second case innovation buds arise in leaf‐axils along the whole length of the season's growth of the flowering shoots, extending to well above the first nodes and up to the base of the inflorescence. Recognition of these two growth‐forms helps to solve the old problem of the correct taxonomic placement of the population from Mont Ventoux (S. France), which must be included in A. aggregata not A. erinacea.
