Description and taxonomic notes.

Medium- to large-sized rhizomatous herbs with Musa - like habit. Inflorescence erect, with peduncle, rachis and cincinnal bracts of various colors from pink to red to yellow; cincinnal bracts distichous or spirally arranged, usually widely separated. Flowers with diurnal anthesis, fully exposed at maturity, resupinate and held at right angles to bracts; perianth generally with short to medium-sized tube, straight to uniformly curved, green to yellow, glabrous; ovary green to yellow to red, generally glabrous. Fruits blue, glabrous. Section Lanea includes species which were formerly placed in sects. Lanea or Cannastrum by Andersson (1985 a, 1992). Here these six species comprise a monophyletic group that is strongly supported ( LPP = 1.0) as sister to a lineage of species with pendent inflorescences which were formerly classified in subgen. Griggsia by Andersson (1992) and Kress et al. (1999).
