|discussion=<p>Matelea edwardsensis is an elusive species with numerous documented localities on and around the eastern and northern margins of the Edwards Plateau, but it appears to be common nowhere. Superficially, it is very similar to M. reticulata, which is almost invariably present where M. edwardsensis occurs. Matelea reticulata differs by stems, leaves, and inflorescences that are more densely vestitured with longer trichomes, rotate corollas that are glabrous adaxially and possess lobes nearly orbiculate and with a more reticulate pattern, and a highly reduced corona lacking noticeable lobes. The seeds of M. edwardsensis are also larger and conspicuously erose at one end. Matelea edwardsensis is frequent across much of its limited range and perhaps not of immediate conservation concern, but its woodland habitat is increasingly vulnerable to clearing and development.</p>
