|discussion=<p><i>Minuartia patula</i> and the related <i>M. muscorum</i> have received little attention in comparison to the granite-outcrop minuartias, the <i>M. uniflora</i> complex. J. A. Steyermark (1941) studied these taxa and described three forms, based chiefly on pubescence variation. Plants entirely glabrous [forma pitcheri (Nuttall) Steyermark] and those with sepals and pedicels somewhat stipitate-glandular (forma media Steyermark) were segregated from densely stipitate-glandular plants (forma patula). We do not feel that such variations deserve formal taxonomic recognition. Forma robusta, as defined by Steyermark, is here referred to <i>M. muscorum</i>.</p><!--
--><p>Most specimens of <i>Minuartia patula</i> have prominently five-veined sepals (seen especially easily in the glabrous forms); occasional plants from Georgia, Kentucky, and Virginia have glabrous sepals with only three strong veins, resembling those of <i>M. muscorum</i>; in other features, including the seeds, they are clearly referable to <i>M. patula</i>. The status of the plants with three-veined sepals remains ambiguous; J. A. Steyermark (1941) included them in his forma media and B. Maguire (1951) included them (in our opinion incorrectly) in his <i></i>var.<i> robusta</i>.</p>
