|discussion=<p><i>Cerastium tomentosum</i> hybridizes readily with the introduced <i>C. arvense </i>subsp.<i> arvense</i> (J. K. Morton 1973).</p><!--
--><p>North American reports of <i>Cerastium</i> biebersteinii de Candolle all appear to be referable to <i>C. tomentosum</i>. The two species are very similar, but C. biebersteinii has flat capsule teeth and is diploid (2n = 36); see M. K. Khalaf and C. A. Stace (2001).</p>
