The geographic range is Argentina; Argentina (Misiones); Brazil; Brazil (Rio Grande do Sul, Minas Gerais, Mato Grosso do Sul, Goiás, Paraná, Santa Catarina, Mato Grosso, Rio de Janeiro, São Paulo) found at elevations of 300-1900 meters with an endangered status of least concern.

Lepismium houlletianum f. regnellii is classified in the subgenus Lepismium.

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

Stems are round and 2 angled, margins have crenations, always dentate (scalloped, serrated like holly), bristles are absent. Basal stems are inderminate (seasonal growth is various lengths), 50cm-100cm x unreported. Main stems are indeterminate (seasonal growth is various lengths), 15cm-40cm x 2.5cm-7.5cm.

Flowers are campanulate or infundibuliform (bell or funnel shaped), 2cm x unreported. Petals 12, sepal count is unreported. Inner petals are white or yellow, outer petals are white or green. Stamen are white with a yellowish base, count is unreported. Stigma lobes from 4 to 5. Flower ovary is cylindrical-angled, unreported x 0.4cm.

Flowering position on the stem is lateral and the flower orientation in relation to the stem is oblique. It is unreported whether flowering repeats per areole. A maximum of 1 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 or sparse at the areoles after flowering.

Unripe fruit is green. Ripe fruit is globose, subglobose or obconical-globose; red, 0.3cm-0.5cm x 0.3cm-0.5cm.

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
