description
Rhipsalis baccifera grows epiphytically or lithophytically with hanging, two-shaped shoots 1 to 4 meters in length. The extension shoots have unlimited growth. Compound areoles sit at the tip of their shoots . The branching is acrotonic . Normal shoots are long, slender, twisting and have a diameter of 4 to 6 millimeters. One or two stiff bristles up to 1 millimeter long sometimes arise from the areoles.
The whitish flowers appearing to the side reach a diameter of 5 to 10 millimeters. The spherical, translucent fruits are white to slightly pink. They have a diameter of 5 to 8 millimeters.
Distribution, systematics and endangerment
Rhipsalis baccifera is common in tropical America and Africa as well as Madagascar , the Seychelles , Mauritius , Réunion and Sri Lanka .
It was first described as Cassyta baccifera in 1771 by Johann Sebastian Mueller . William Thomas Stearn placed them in the genus Rhipsalis in 1939 .
The following subspecies are distinguished:
- Rhipsalis baccifera subsp. baccifera
- Rhipsalis baccifera subsp. cleistogama M. Kessler & al.
- Rhipsalis baccifera subsp. erythrocarpa (K.Schum.) Barthlott
- Rhipsalis baccifera subsp. hileiabaiana N.P. Taylor & Barthlott
- Rhipsalis baccifera subsp. horrida (Baker) Barthlott
- Rhipsalis baccifera subsp. mauritiana (DC.) Barthlott
- Rhipsalis baccifera subsp. shaferi (Britton & Rose) Barthlott & NPTaylor
The subspecies Rhipsalis baccifera subsp. hileiabaiana was in the Red List of Threatened Species of IUCN in 2002 as " Vulnerable (VU) , d". H. endangered, classified. After the list was revised in 2013, the species will be classified as " Least Concern (LC) ", i. H. listed as not endangered, the subspecies Rhipsalis baccifera subsp. hileiabaiana was not re-recorded.
