The Weberocereus View in CoL clade
Weberocereus View in CoL is depicted as polyphyletic. A clade containing five species, including W. tunilla (F.A.C. Weber) Britton & Rose View in CoL —the type species—is supported with 1 PP, 82% MLBS, 80% JK, but W. glaber View in CoL and W. tonduzii View in CoL are resolved at different positions within Selenicereus View in CoL . The Weberocereus View in CoL clade has two subclades: W. tunilla View in CoL and W. trichophorus View in CoL are resolved as sisters with maximum support. These two species are morphologically similar, with thin (less than 15 mm in diameter), pendent stems, campanulate flowers, and purple fruit pulp. The second subclade contains Weberocereus frohningiorum Ralf Bauer View in CoL , W. imitans View in CoL and W. rosei (Kimnach) Buxbaum View in CoL , but is supported by only 0.5 PP, 54% MLBS and is not found by the MP analysis, although W.rosei View in CoL and W. imitans View in CoL are highly supported as sister species. These three species constitute the Eccremocactus group sensu Bauer (2003a) and are morphologically characterized by flattened or 3-ribbed stems, and white fruit pulp. Among the hylocereoid clade, W. imitans View in CoL and W. rosei View in CoL share the flat stems with Selenicereus anthonyanus View in CoL , and together the three species were included in Cryptocereus ( Backeberg 1959) . However, our results show that Weberocereus species are not related to S. anthonyanus View in CoL . The flat stem character state is convergent between clades within Hylocereeae and also occurs in Disocactus View in CoL , Epiphyllum View in CoL and Pseudorhipsalis View in CoL . Weberocereus View in CoL is morphologically heterogeneous in the current circumscription and is not well separated from Hylocereus or Selenicereus View in CoL . The main difference is that the flowers of Weberocereus View in CoL are smaller (less than 7 cm in length) compared to those of Hylocereus / Selenicereus View in CoL . Weberocereus glaber View in CoL and W. tonduzii View in CoL (type species of Werckleocereus ) represent the Werckleocereus group ( sensu Bauer 2003a ) and are resolved within the Hylocereus / Selenicereus View in CoL assemblage, with which they share 3-ribbed stems and white nocturnal flowers with dark spiny pericarpels. So, morphologically, they do fit well within the Hylocereus / Selenicereus View in CoL assemblage.
