Description
| The synonym of Rhipsalis dissimilis f. dissimilis, Rhipsalis spinescens paratype material collected by Olsthoorn is not published. Due to the deviation in the botanical description from the accepted taxon type description, we have allowed for a distinct description for this older taxon. The intent is to alleviate too broad of a description for proper identification. The geographic range is Brazil (Atibaia, Pedra Grande, São Paulo) found at elevations of 800-1103 meters with an endangered status of endangered. Rhipsalis spinescens paratype material collected by Olsthoorn is classified in the subgenus Calamorhipsalis. Observed growing as an lithophyte. Overall habit is erect or semi-erect, branches are dimorphic (more than one stem shape) and acrotoinic (stems form from the tips of previous stems). Stems are round and slightly angled, bristles are absent to sparse to dense. Basal stems are indeterminate (seasonal growth is various lengths), 40cm x unreported. Main stems are determinate (seasonal growth is about the same length), 20cm x 1.5cm. Flowers are rotate; sub-patent or patent (wheel shaped: partial to wide open), unreported x unreported. Petals from 7 to 9, sepals from 3 to 5. Inner petals are translucent-white or translucent-light-yellow, outer petals are yellow, orange, brown or red. Stamen are white or cream, from 80 to 91. Stigma lobes from 4 to 5. Flower ovary shape is unreported, unreported x unreported. Flowering position on the stem is lateral to subapical and the flower orientation in relation to the stem is oblique. Does repeat flowering per areole. A maximum of 1 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 color is unreported. Ripe fruit shape is unreported; color is unreported, unreported x unreported. Other notable features: Reduced under R. dissimilis f. dissimilis in 1995 by Wilhelm Barthlott. This species was not part of any known molecular phylogenetic test.
