--><span class="statement" id="st-undefined" data-properties="">Herbs; latex white, dilute. <b>Stems</b> usually solitary, erect, unbranched, unarmed, densely hirsute with long, eglandular and minutely glandular trichomes. <b>Leaves</b> persistent, opposite, petiolate, surfaces densely hirsute with long, eglandular and minutely glandular trichomes; stipular colleters absent; laminar colleters present. <b>Inflorescences</b> extra-axillary, cymose, umbelliform, solitary at nodes, sessile or pedunculate. <b>Flowers</b>: calycine colleters apparently absent; corolla cream with longitudinal green lines, urceolate [campanulate], lobes erect to spreading, aestivation contort-dextrorse; corolline corona absent; androecium and gynoecium united into a gynostegium adnate to corolla tube; gynostegial corona of 5 laminar segments opposite stamens, distinct, fused to gynostegium at base of anthers; anthers adnate to style, apex with laminar appendages covering margins of style apex, locules 2; pollen in each theca massed into a rigid, horizontally oriented pollinium, pollinia strongly curved, bearing sterile, navicular portion adjacent to translator, pollinia of adjacent anthers joined by translators to common corpulsculum, together forming a pollinarium. <b>Fruits</b> follicles, typically solitary, sharply deflexed, fusiform, surface smooth, densely villous or hirsute, tardily glabrate. <b>Seeds</b> winged, not beaked, ovate, flattened, comose, not arillate.</span><!--

--><p>Pherotrichis was formerly included in a broadly circumscribed, paraphyletic Matelea and is distinctive in subtribe Gonolobinae (which also includes Gonolobus and Matelea) by the erect, non-twining habit and the densely barbate corolla lobes. The removal of Pherotrichis from Matelea is but one of several generic realignments necessary to circumscribe a monophyletic Matelea. Species of Pherotrichis are very commonly mistaken for Asclepias but are readily distinguished by the urceloate (or campanulate in extra-regional species) corollas with villous lobes concealing the minute corona and by the sharply deflexed follicles.</p>
