Description
| The accepted name Rhipsalis shaferi Britton & Rose was published in Cactaceae 4: 229. 1923. The geographic range is Paraguay, southern Bolivia, northern Argentina found at elevations of 1600 meters with an endangered status of least concern. Rhipsalis shaferi is classified in the subgenus Rhipsalis. Observed growing as an epiphyte. Overall habit is erect or pendant, branches are dimorphic (more than one stem shape) and acrotonic (stems form from the tips of previous stems). Stems are round, bristles are absent. Basal stems are indeterminate (seasonal growth is various lengths), 50cm x 0.3cm-0.5cm. Main stems are determinate (seasonal growth is about the same length), 4cm-9cm x 0.2cm-0.5cm. Flowers are rotate: sub-patent or patent (wheel shaped: partial to wide open), 0.5cm-0.8cm x 0.4cm-0.7cm. Petals from 4 to 8, sepals 1. Inner petals are white, light-yellow or light-green, outer petals are white, green, peach, pink or brown. Stamen are white, from 20 to 25. Stigma lobes from 2 to 4. Flower ovary is globose or ovoid, 0.25cm-0.4cm x 0.25cm-0.29cm. Flowering position on the stem is lateral to subapical and the flower orientation in relation to the stem is perpendicular. Does not repeat flowering per areole. A maximum of 2 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 green or brown. Ripe fruit is globose, subglobose or ovoid; white or pink, 0.75cm x 0.2cm-0.6cm. Other notable features: Closely related to and commonly confused with forms of R. teres, it can be distinguished by having a flower ovary that is typically longer than the petal parts of the flower during most of the bud of development, flowers are a pale yellow to white as they die, and remain attached to the flower ovary. Once classified as a subspecies of R. baccifera, R. shaferi is quite similar. It is somewhat distinguishable by having typically shorter and stouter stems than R. baccifera subsp. baccifera. The majority of specimen I have seen also exhibit more consistently pointed flower buds, a trait that was caught in the botanical plate in The Cactaceae, by Britton & Rose, 1923. Certain species can be more prone to producing betalains that color the stems reddish in higher light conditions, R. shaferi is one of them, however stem color is not a good identifying characteristic for any species. It is highly inconsistent within the species populations. Taxonomic treatment and description were derived from:
