Description and taxonomic notes.
Medium- to large-sized rhizomatous herbs with Musa - 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 (or rarely so), and fully or partially enclosed in bracts; perianth uniformly curved (rarely s-shaped), white to green to yellow; ovary green to yellow to red. Fruits blue, glabrous. Species in this section can be quite variable in most reproductive features, although almost all have non-resupinate flowers enclosed in the cincinnal bracts. The 0.99 LPP support identifies this clade as distinct from its sister taxon sect. Aurantiacae. The genomic data place H. lourteigiae L. Emygdio & Santos in sect. Stenochlamys, however, the shape and orientation of the cincinnal bracts and non-resupinate, enclosed flowers suggest that this species is more properly placed in sect. Taeniostrobus.
