Abstract

Individuals of Plantago lanceolata and Salvia lyrata, both herbaceous perennial species, were transplanted into plots of otherwise unmanipulted vegetation. Individuals came from one of 12 half-sibships (common mother). Individuals were marked and leaf and inflorescence numbers counted at intervals for 14 mo. Consistent differences among plots, in survivorship, size, and reproduction, were found in both species, although the plots were only metres apart. Causes of this spatial variation are discussed. Evidence for genetic and genetic x environmental variation in Plantago lanceolata is suggestive but not conclusive.
