Description and taxonomic notes.

Small- to large-sized rhizomatous herbs with Musa -, Canna -, or Zingiber - like habit. Inflorescence erect (rarely pendent), with peduncle, rachis and cincinnal bracts of various colors from pink to red to orange to yellow; cincinnal bracts distichous or spirally arranged. Flowers with diurnal anthesis, not resupinate and fully or partially enclosed in bracts or fully resupinate and held at right angles to bracts; perianth uniformly curved (rarely s-shaped), white to green to yellow; ovary green to yellow to red. Fruits blue, glabrous. subgenus Taeniostrobus in the current classification is made up of two sections (sects. Taeniostrobus and Aurantiacae ) and includes species from four earlier designated subgenera (subgens. Taeniostrobus , Heliconia , Stenochlamys , and Griggsia ), although the majority of species were included in Andersson’s subgen. Heliconia sect. Tortex . Few, if any, morphological traits are shared by all species across subgen. Taeniostrobus . The very high strong support ( LPP = 1.0) in the phylogenomic analysis is primary evidence for uniting these species into a single monophyletic subgenus with two somewhat distinct sections.
