Rhipsalis oblonga Loefgr.

Origin and Habitat:

Southern Bahia, Espirito Santo, Rio de Janeiro, and Sao Paulo, Brazil (area of occupancy of less than 2,000 km2).
Type locality:On Ilha Grande, Brazil.
Altitude range: It occurs from sea level up to 2,000 metres above sea level.
Habitat and Ecology: It is a humid forest element: epiphyte in very shaded Mata atlântica, at low elevations. It is a very localized and fragmented species as it only occurs in very humid places. The population is declining because of habitat destruction due to expanding agriculture and urbanization plus logging, especially in the northern part of its range. The northern-most localities have probably been lost.

Description:Rhipsalis oblonga is a semierect to pendent, epiphytic or lithophytic shrubs, 2.50 m long, with main stems terete at base becoming flattened above and branching apical or lateral. It is a very free-flowering species with pinkish-white fruits.
Stems: Dimorphic. Main branches terete below, three-angled, or winged more or less flattened above up to 20 cm long and 2 cm across, freely emitting aerial roots. Ultimate branches narrowly-oblong, very thin, flattened, 5-9(-15) cm long, 3-6 cm cm broad, ca.1 mm thick away from midrib, cuneate to truncate at base, truncate at apex, with prominent veins, dark to pale green or olive-yellow green, sometimes purplish, margins wavy to plane, crenate and lobed.
Areoles: Between the indentation, 2-4 mm from branch segment margin, 1.4-3.3 cm apart, first of segment 3-5.5 cm distant from segment base; when sterile 1-2.5 mm diam, with vestigial hairs and scales; when fertile woolly, 1-2.5 mm on diameter, with 1 acicular scale, scarce marginal hairs and sometimes bearing 1 or more small bristly spines after flowering
Flowers: 1-2 per areole, borne along the sides of the branches, solitary at the areoles, rotate, yellowish white, to 12-18 mm long. Sepaloid tepals 3-4, interior petaloid tepals 5, reflexed, greenish yellow rarely with reddish apex. Stigma (3-) 4-5, up to 3 mm long. Stamens whitish numerous.
