The section Heliconia comprises stout musoid species with erect inflorescences, thick, deeply cymbiform spathes and greenish flowers on untwisted pedicels. Seven species are recognized viz.: (1) H. bihai (L.) L., (2) H. rodriguensis Aristeg., (3) H. caribaea Lam., (4) H. bourgaeana Peters., (5) H. stricta Huber, (6) H. wagneriana Peters, and (7) H. ortotricha Anderss. sp. nov. The circumscription of the section is discussed, and it appears that closest affinities are with H. latispalha Benth., H. spatho–circinata Aristeg. and allied species, and also with H. lourteigii Emygdio & Santos and H. tenebrosa Macbr. Two groups can be discerned in the section, one comprising species 1–3 and the other species 5–7, H. bourgaeana occupying a somewhat isolated and more or less intermediate position. A key to species is given and each species is described and illustrated. Particular attention is paid to variation in diagnostically important features.
