• Epiphyte in shaded habitat, 1-1.5 m long, branching apical.
• Stem segments flattened in longitudinal section, 0.5-1.5 mm diam, dark green, delicate, fragile, monomorphic, 7-12 cm long, base attenuate, apex truncate, wings 2, (0.2-)0.45-1 (1.2) cm wide, margin serrate, plane, rare slightly undulate, with 2-3 mm projections, midrib 2-3 mm diam, cylindric.
• Areoles between margin projections, 1.5-3.5 cm apart, first of segment 4-8(-10) distant from segment base; when sterile 1 mm diam, with 2 acicular reddish scales; when fertile 1.5 mm diam, with 1-3 acicular scales, 1(-2) flowers/fruits.
• Flowers ca. 8 mm diam; pericarpel 2-4 X 2-3 mm, cylindric, greenish, glabrous or with sepaloid bract; with 1-3 sepaloid tepals, 0.3-1.5 mm long and 6 petaloid tepals, 3-4.2X2-2.3 mm, wide elliptic, patent to sub-erect, whitish, apex rounded, slightly cucullate, margin straight. Style 3-4 mm long; stigma with 3-5 lobes, ca. 1 mm long, ligulate, spreading. Ovules in 3 rows, funicle short (< 0.5 mm long). Stamens ca. 40, 1.5-2.5 mm long, internal shorter, internal erect and external facing inwards, white. Nectary ca. 0.4 mm long. Fruit 7-9X7-8 mm, globose, whitish, glabrous. Figure 7: G.

Notes; Rhipsalis cuneata subsp. australis can be distinguished from R. cuneata subsp. cuneata by the narrow stem segments with narrow projections in the margin.

Habitat and distribution: Occurs in the Chaparre region from 200-700 m (Cochabamba and Santa Cruz, Bolivia). Figure 8.
