Description

The accepted name Rhipsalis clavata f. clavata F. A. C. Weber was published in Rev. Hort. (Paris) 64: 429. 1892.

The geographic range is Brazil (São Paulo, Minas Gerais, Rio de Janeiro) found at elevations of 0-1600 meters with an endangered status of near threatened.

Rhipsalis clavata f. clavata is classified in the subgenus Erythrorhipsalis.

Observed growing as an epiphyte. Overall habit is pendant, branches are monomorphic or rarely dimorphic (single or 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), 6cm-15cm x 0.015cm-0.5cm. Main stems are determinate (seasonal growth is about the same length), 1.5cm-7cm x 0.1cm-0.3cm.

Flowers are campanulate (bell shaped), 1.3cm-1.5cm x 1cm-2.3cm. Petals from 7 to 11, sepals from 4 to 6. Inner petals are white, outer petals are white, cream, green or pink. Stamen are white, from 12 to 23. Stigma lobes from 3 to 5. Flower ovary is obconical, 0.2cm-0.3cm 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 3 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 white, green or pink. Ripe fruit is globose or subglobose; white, light-yellow, light-green, light-pink or red, 0.45cm-0.5cm x 0.45cm-0.6cm.

Other notable features:
Ripe fruit sometimes has a pinkish ring at the top. While ripe fruit is most commonly white there have been red variants reported. Flower more expanded and stems consistently shorter, thicker, and more robust than R. clavata f. delicatula. It is rare for R. clavata to produce long basal stems typical of the other Rhipsalis in subgenus Erythrorhipsalis. In my collection, and observed in other collections, this species typically maintains a shorter compact bushier appearance and is slower growing than R. clavata f. delicatula. Certain species can be more prone to producing betalains that color the stems reddish in higher light conditions, R. clavata is one of them, however stem color is not a good identifying characteristic for any species. It is highly inconsistent within the species populations.

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
