Description

The accepted name Rhipsalis pilocarpa Loefgr. was published in Monatsschr. Kakteenk. 13: 52. 1903.

The geographic range is Brazil (Espírito Santo, Rio de Janeiro, Paraná, Minas Gerais, São Paulo) found at elevations of 500-900 meters with an endangered status of vulnerable.

Rhipsalis pilocarpa is classified in the subgenus Erythrorhipsalis.

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

Stems are round, bristles are dense to sparse. Basal stems are indeterminate (seasonal growth is various lengths), 8.5cm-40cm x 0.2cm-0.6cm. Main stems are determinate (seasonal growth is about the same length), 2.5cm-7cm x 0.1cm-0.3cm.

Flowers are campanulate (bell shaped), 0.8cm-1.2cm x 0.7cm-2.5cm. Petals from 10 to 15, sepals from 5 to 6. Inner petals are white, cream, pink or light-purple, outer petals are white, pink or purple. Stamen are white, from 51 to 83. Stigma lobes from 6 to 7. Flower ovary is obconical, 0.5cm x 0.4cm.

Flowering position on the stem is 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. Ripe fruit is globose; magenta or red, 1.2cm x 0.8cm-1.2cm.

Other notable features:
R. pilocarpa is easily distinguishable by the dense bristles at the areoles, flower ovary and ripe fruit are also generally covered in bristles. Floral disc at the base of the stamen often, but not always, reddish. Commonly confused with R. baccifera subsp. horrida which it is not very closely related1 and is easily distinguished by the bristles usually laying flat against the stems and angled toward the tip, the much larger flowers, and the much larger ripe magenta fruit. R. baccifera subsp. horrida stems also commonly have a slight angled appearance where R. pilocarpa stems are more consistently rounded. Certain species can be more prone to producing betalains that color the stems reddish in higher light conditions, R. pilocarpa is one of them, however stem color is not a good identifying characteristic for any species. It is highly inconsistent within the species populations.

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
