Description

The accepted name Rhipsalis juengeri Barthlott & N. P. Taylor was published in Bradleya 13: 50. 1995.

The geographic range is Brazil (Espírito Santo, São Paulo, Minas Gerais) found at elevations of 700-1600 meters with an endangered status of least concern.

Rhipsalis juengeri is classified in the subgenus Erythrorhipsalis.

Observed growing as an epiphyte. Overall habit is pendant, branches are dimorphic (more than one stem shape) and acrotonic (stems form from the tips of previous stems).

Stems are round and slightly clavate, bristles are absent. Basal stems are indeterminate (seasonal growth is various lengths), 20cm-200cm x 0.2cm-0.3cm. Main stems are determinate (seasonal growth is about the same length), 0.16cm-6cm x 0.08cm-0.25cm.

Flowers are campanulate (bell shaped), 0.7cm-1.5cm x 0.4cm-1.5cm. Petals from 10 to 14, sepal count is unreported. Inner petals are white, outer petals are white, cream, green or pink. Stamen are yellow, from 23 to 44. Stigma lobes from 2 to 3. Flower ovary is obconical, 0.2cm-0.3cm x 0.1cm-0.25cm.

Flowering position on the stem is subapical to apical and the flower orientation in relation to the stem is parallel. Does not repeat flowering per areole. A maximum of 4 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, white, pink, brown or red. Ripe fruit is globose or subglobose; green, pink, magenta, purple or red, 0.4cm-0.6cm x 0.4cm-0.5cm.

Other notable features:
Ripe fruit reported to smell of black currents. Identifying characteristics that help to differentiate R. juengeri from other similar closely related1,2 species R. burchellii, R. ormindoi, and R. campos-portoana are the yellow colored stamen, ripe reddish or greenish fruit, and distinct fruit shape. Ripe green fruit sometimes has a reddish ring at the top.

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
