Description
| The accepted name Rhipsalis pittieri Britton & Rose was published in The Cactaceae 4: 1923. The geographic range is Venezuela (Yaracuy, Carabobo, Aragua, Distrito Federal, Miranda) found at elevations of 1500 meters with an endangered status of data deficient. Rhipsalis pittieri is classified in the subgenus Phyllarthrorhipsalis. Observed growing as an epiphyte. Overall habit is pendant or semi-erect, branches are monomorphic (single stem shape) and acrotonic (stems form from the tips of previous stems). Stems are round, bristles are absent. Main stems are determinate (seasonal growth is about the same length), 6cm-25cm x 0.5cm-0.6cm. Flowers are rotate: sub-patent or patent (wheel shaped: partial to wide open), unreported x 1cm-1.3cm. Petals from 5 to 9, sepal count is unreported. Inner petals are white, light-yellow, light-yellow-green, light-green or light-purple, outer petals are white, green, pink or purple. Stamen are white, from 13 to 18. Stigma lobes from 3 to 4. Flower ovary is subglobose or globose, unreported x unreported. 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 2 flowers were reported at a single areole. Areole position in the stems is semi-immersed (flower ovary is partially hidden in the stems during bud development). Trichomes or wool is sparse at the areoles after flowering. Unripe fruit is green, brown or red. Ripe fruit is globose; white, 0.4cm-0.57cm x 0.48cm-0.58cm. Other notable features: Once classified as a subspecies of R. floccosa this species is distinguishable by the much smaller flowers and fruit. This species is more closely related to R. grandiflora than R. floccosa1. The general morphology between the two is similar, however R. pittieri does have semi-immersed areoles which result in semi-erumpent flower buds. During bud development the flower ovary will either be partially or fully hidden in the stems. 1Phylogeny and evolution of the epiphytic Rhipsalideae (Cactaceae), Nadja Korotkova, Ph.D. Thesis, 2012 Taxonomic treatment and description were derived from:
