Description

The accepted name Rhipsalis dissimilis f. dissimilis (G. Lindb.) K. Schum was published in Fl. Bras. 4(2): 286. 1890. The geographic range is Brazil (Sao Paulo, in the hills of the middle river Tiefe. Sao Paulo, Itararé) found at elevations of 800-1100 meters with an endangered status of endangered. Rhipsalis dissimilis f. dissimilis is classified in the subgenus Calamorhipsalis. Observed growing as an epiphyte or lithophyte. Overall habit is semi-erect or pendant, branches are dimorphic (more than one stem shape) and acrotonic (stems form from the tips of previous stems). Stems are round and 3 to 8 angled, bristles are absent to sparse to dense. Basal stems are indeterminate (seasonal growth is various lengths), 5cm-15cm x 0.5cm-1.2cm. Main stems are determinate (seasonal growth is about the same length), 5cm-8cm x 0.5cm-0.7cm. Flowers are rotate: sub-patent, patent or reflexed (wheel shaped: partial to wide open to reflexed), 1.2cm-1.3cm x 1cm-2.8cm. Petals from 7 to 12, sepal count is unreported. Inner petals are white, cream or light-yellow, outer petals are peach, pink, purple, red or brown. Stamen are cream or yellow, from 40 to 60. Stigma lobes from 4 to 8. Flower ovary is obconical, 0.4cm x unreported. Flowering position on the stem is lateral and the flower orientation in relation to the stem is oblique. Does repeat flowering per areole. A maximum of 3 flowers were reported at a single areole. Areole position in the stems is deeply immersed (flower ovary is partially or fully hidden in the stems during bud development). Trichomes or wool is dense at the areoles after flowering. Unripe fruit is green, pink, red or brown. Ripe fruit is globose; white or pink, unreported x 0.8cm-1cm. Other notable features: Can be distinguished from the closely related R. trigonoides1,2 by the weaker 3+ angled stems, commonly produces more than a single flower at an areole, some stems often present with bristles, and typically has more narrow petals. Nadja Korotkova indicates R. dissimilis f. dissimilis is more closely related to the group of R. floccosa, and R. trigonoides than R. dissimilis f. epiphyllanthoides1. We may see some change in the current taxonomy for this species. Lower stems commonly 7 to 8 angled covered in bristles, upper stems typically 3 to 4 angled without bristles. 1Phylogeny and evolution of the epiphytic Rhipsalideae (Cactaceae), Nadja Korotkova, Ph.D. Thesis, 2012 2Molecular phylogeny, evolution and systematics of Rhipsalis (Cactaceae), Alice Calvente, Ph.D. Thesis, 2010 Taxonomic treatment and description were derived from: The referenced publications below published material was examined and consolidated to determine minimum and maximum size ranges to determine color variations and shapes In rare cases if minimum and maximum values were unreported, authors examined their own materials if clearly observed colors were unreported, authors expanded the botanical descriptions
