|discussion=<p><i>Hypericum setosum</i> is the only American <i>Hypericum</i> sp. with an indumentum. It is related to <i>H. virgatum</i> (<i>H. denticulatum</i> subsp. acutifolium); in addition to having the indumentum, it is generally smaller and less branched and has a different chromosome number.</p>
