Description
| The accepted name Rhipsalis neves-armondii f. megalantha (Loefgr.) Barthlott & N.P.Taylor was published in Bradelya 13:50. 1995. The geographic range is Brazil (São Paulo (Campinas, Ilha de São Sebastião, Mun. Ilhabela)) found at elevations of 0-1001 meters with an endangered status of least concern. Rhipsalis neves-armondii f. megalantha is classified in the subgenus Calamorhipsalis. Observed growing as an epiphyte or lithophyte. Overall habit is pendant or semi-erect, branches are dimorphic or monomorphic (single or more than one stem shape) and acrotonic (stems form from the tips of previous stems). Stems are round, bristles are absent to sparse to dense. Basal stems are indeterminate (seasonal growth is various lengths), 18cm-35cm x 0.5cm-1cm. Main stems are determindate (seasonal growth is about the same length), 8cm-15cm x 0.8cm-1cm. Flowers are rotate: sub-patent or patent (wheel shaped: partial to wide open), unreported x 3.5cm-4cm. Petals from 8 to 12, sepal count is unreported. Inner petals are white, light-yellow, light-green or pink, outer petals are white, yellow, green or pink. Stamen are yellow, orange or pink, from 80 to 130. Stigma lobes from 6 to 8. Flower ovary is subglobose or obconical, unreported x unreported. Flowering position on the stem is lateral to apical and the flower orientation in relation to the stem is oblique. Does not 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 is white, cream, green, pink, brown or red. Ripe fruit is globose or subglobose; pink, magenta, purple or red, 1.2cm x 1.2cm. Other notable features: R. neves-armondii f. megalantha has the largest flower reported of any Rhipsalis species typically over 3.5cm. Easily distinguished by the large stem diameter and flower size, partial to wide open wheel shaped flowers with yellow or orange-pink colored stamen, and determinate stem habit (main stems that consistently grow to about the same length each seasonal). Certain species can be more prone to producing betalains that color the stems reddish in higher light conditions, R. neves-armondii is one of them, however stem color is not a good identifying characteristic for any species. It is highly inconsistent within the species populations. At times with a reddish or purplish coloring around the areoles, but that is not a good identifying characteristic for any species as R. puniceodiscus, R. baccifera subsp. mauritiana, R. grandiflora, R. floccosa, and R. ewaldiana at least, also inconsistently exhibit this characteristic. Comments: Forms are often recognized at the extreme morphological characterization found in nature, however this species presents a high level of plasticity and varying intermediate morphologies are reported between the various forms.
