Description
| The accepted name Rhipsalis oblonga Loefgr. was published in Arch. Jard. Bot. Rio. de Janeiro 2: 36-37. 1918. The geographic range is Brazil (Rio de Janeiro, São Paulo, Bahia) found at elevations of 0-2000 meters with an endangered status of vulnerable. Rhipsalis oblonga is classified in the subgenus Phyllarthrorhipsalis. Observed growing as an epiphyte. Overall habit is pendant, branches are dimorphic or monomorphic (single or more than one stem shape) and acrotonic or mesotonic (stems form from the tips to middle of previous stems). Stems are 2 to 3 angled, margins have low to deep crenations, at times undulating or frilled (slightly to deeply scalloped), bristles are absent. Basal stems are indeterminate (seasonal growth is various lengths), 10cm-20cm x 1cm-2cm. Main stems are determinate (seasonal growth is about the same length), 8cm-23cm x 2cm-7cm. Flowers are rotate: patent or reflexed (wheel shaped: wide open to reflexed), 0.9cm-1.5cm x 1cm-1.8cm. Petals 5, sepals from 1 to 4. Inner petals are light-yellow, yellow or green, outer petals are yellow, green, pink or red. Stamen are white, from 20 to 46. Stigma lobes from 3 to 5. Flower ovary is cylindrical, 0.13cm-0.4cm x 0.1cm-0.4cm. Flowering position on the stem is lateral and the flower orientation in relation to the stem is perpendicular. Does repeat flowering per areole. A maximum of 3 flowers were reported at a single areole. Areole position in the stems is superficial (flower ovary is visible on the surface of the stems during bud development). Trichomes or wool is absent at the areoles after flowering. Unripe fruit is yellow or green. Ripe fruit is globose; white or green, 0.5cm-0.8cm x 0.5cm-0.8cm. Other notable features: Ripe fruit sometimes has a pinkish ring at the top. R. oblonga is closely related to1,2 and can be difficult to distinguish from some specimen of R. barthlottii, R. crispata, R. cuneata, and R. occidentalis. It often has quite thin stems, almost construction paper thin. The thinness of the stems can, at times, result in an undulating or frilly margin, but that is not a good identifying characteristic for this species as R. barthlottii, R. crispata, R. occidentalis, R. cuneata, R. goebeliana, and R. rhombea can also inconsistently present the same characteristic. Stems can be anywhere from the length and width of a finger tip to over the length and width of a hand. The most identifiable characteristics are the thin stems, white fruit, fruit shape, white and light-yellow to yellow flowers, small equilaterally sized ovaries, and often longer petals.
