Description

The accepted name Rhipsalis micrantha f. rauhiorum (Barthlott) Süpplie was published in Rhipsalidinae, ed. 4: 101. 1994.

The geographic range is Ecuador found at elevations of 1600-1700 meters with an endangered status of least concern.

Rhipsalis micrantha f. rauhiorum is classified in the subgenus Phyllarthrorhipsalis.

Observed growing as an epiphyte or lithophyte. Overall habit is pendant or semi-erect, branches are monomorphic (single stem shape) and acrotonic or mesotonic (stems form from the tips to middle of previous stems).

Stems are 2 to 4 angled, margins have crenations (scalloped), bristles are absent to sparse. Main stems are determinate (seasonal growth is about the same length), 5cm-14cm x 0.8cm-2cm.

Flowers are rotate: sub-patent, patent or reflexed (wheel shaped: partial to wide open to reflexed), 0.8cm-0.9cm x 0.95cm-1cm. Petals from 5 to 7, sepals from 1 to 3. Inner petals are white, light-yellow, light-green or pink, outer petals are white, light-yellow, green or pink. Stamen are white, from 19 to 40. Stigma lobes from 4 to 5. Flower ovary is globose or cylindrical, 0.3cm-0.35cm x 0.25cm-0.3cm.

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 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 pink. Ripe fruit is globose or ovoid; white, 0.7cm x 0.5cm-0.6cm.

Other notable features:
Ripe fruit sometimes has a reddish ring at the top. While the flowers are predominantly white, I've observed almost entirely pale pink flowering specimen, at times they can even have a yellow-orange appearance.

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.

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
