title: Orobanche elatior and O. kochii (Orobanchaceae) in Poland: distribution, taxonomy, plant communities and seed micromorphology
abstract: Species of the genus &lt;em&gt;Orobanche&lt;/em&gt; (Orobanchaceae), parasitic on &lt;em&gt;Centaurea&lt;/em&gt; in Central Europe, were previously considered to belong to the &lt;em&gt;O. elatior&lt;/em&gt; group. At present, the taxon is differentiated into two species, &lt;em&gt;O. elatior&lt;/em&gt; Sutton and &lt;em&gt;O. kochii&lt;/em&gt; F.W. Schultz. The paper presents for the first time the distribution of &lt;em&gt;O. elatior&lt;/em&gt; and &lt;em&gt;O. kochii&lt;/em&gt; in Poland base
