--><p><i>Agrostemma</i> brachyloba (Fenzl) Hammer (<i>A. gracilis</i> Boissier), a species native to Greece and Asia Minor, has been reported as a garden waif in Boulder, Colorado, where it persisted for at least four years (W. A. Weber et al. 1979). It differs from <i>A. githago</i> in that its calyx lobes are shorter (rather than longer) than the calyx tube, and its petals, spotted on the limb, are longer (rather than shorter) than the calyx lobes.</p>
