Inflorescence pendent, with peduncle, rachis and cincinnal bracts usually red with yellow distally along margins (rarely completely yellow or green); cincinnal bracts sub-distichous to spirally arranged, separated. Flowers with diurnal anthesis, not resupinate and fully to partially enclosed in bracts; perianth with short to medium-sized tube, uniformly curved, yellow to green, glabrous; ovary white to green to yellow, glabrous. Fruits blue, glabrous. Most of the species in this section have been considered as related and informally placed in the <i>H. platystachys</i> group (Andersson 1985 b, 1992) or the unpublished sect. <i>Pendulae</i> (Kress et al., 1999). The strong LPP support (0.92) for sect. <i>Pastazae</i> is further evidence for its recognition as a distinct monophyletic lineage within subgen. <i>Heliconia</i>.</p><p><b>Species.</b></p><p>* <i>Heliconia abaloi</i> G.
