Data from: Molecular and morphological evidence reveals a new species of Antiphytum (Echiochiloideae, Boraginaceae) from Guerrero, Mexico
<p>Molecular and morphological evidence supports a new species in the genus <i>Antiphytum</i> from the Sierra Madre del Sur, in the state of Guerrero, Mexico, here described as <b><i>A. brevicalyx</i></b>. This species is unique in the genus by possessing a calyx shorter than the corolla tube at anthesis; it is similar to <i>A. floribundum</i> in inflorescence arrangement, but differs from that species in lacking a basal leaf rosette and having appendages on the corolla throat. According to phylogenetic analysis of nuclear ITS and plastid <i>ndhF-rpl32 </i>sequences representing seven of the eight North American species of the genus besides the proposed new species, accessions of <i>A. brevicalyx<b> </b></i>form a well-defined clade within <i>Antiphytum</i>, corroborating its distinctive morphology. However, the analyses do not resolve the phylogenetic position of <i>A. brevicalyx </i>within the genus.</p>
