Brazil: Rio Grande de Sul, Mun. Agudo

According to Andreas Hofacker (pers. comm. to N.P. Taylor) the plant is known only from a single hill at Agudo and was not seen by Horst & Uebelmann elsewhere.


Rhipsalidi cereoidi primo adspectu habitu similis, sed segmenta caulium alata incisa; R. russellii etiam similis sed flores majors segmentis perianthii multis instructi.A


The plant produces stiffly robust stems of spreading to pendulous habit; stem-segments of determinate growth, to c. 15 x 4 cm, slightly tapered to the base, 3--4(-5)-angled/winged, but notched at the areoles and mostly spineless; flowers are borne 1 to few together, c. 1.5-2.0 cm 0, with c. 11 narrow, white perianth-segments visible from above; and fruit up to 6 x 5 mm, pale to magenta-pink depending on age and exposure to sun.A
