The earlier lectotypification ofC. strictumL. is superseded as being in conflict with the protologue. The new lectotype, a specimen in the Burser Herbarium explicity cited in the protologue, agrees with the original diagnosis and belongs toArenaria grandifloraL. As a consequence,C. strictumL. becomes a taxonomic synonym ofA. grandiflora.The oldest legitimate name forC strictumauct.nonL., isC. arvenseL. var.strictumKoch. Since most authors have usedC. strictumin a sense excluding the Linnaean type, its treatment as a synonym ofA. grandiflora, fits the widely held idea that Linnaeus described underC. strictumsomething that did not belong inCerastium.Types forC. arvenseL. var.strictumKoch andA. grandifloraL. are also designated.
