--><p><i>Hypericum lissophloeus</i> is found in Bay and Washington counties. The larger capsules, one- to three-flowered, lateral inflorescence branches, and smooth-polished, metallic bark (that exfoliates like that of <i>Betula</i> species) are among the features that distinguish <i>H. lissophloeus</i> from <i>H. fasciculatum</i>, <i>H. nitidum</i>, and their allies (<i>H. brachyphyllum</i> and <i>H. chapmanii</i>).</p>
