ensis (F. Ritter) Barthlott & N. P. Taylor 1995 Rhipsalis monteazulensis F. Ritter 1979 Rhipsalis floccosa subsp. oreophila N. P. Taylor & Zappi 1998

Plants epiphytic or lithophytic, much branched, erect at first, becoming pendent, growth determinate, branching strictly acrotonic. Stem segments cylindrical, slender, round in cross section, often with raised podaria subtending the scale leaves, green but sometimes tinged with red or purple near the areoles, to 25 cm (9.8 in) long, 5-6 mm (0.2 in) in diameter. Areoles sunken, woolly, without bristles. Flowers borne laterally, greenish white to creamy white or golden yellow, 15-20 mm (0.6-0.8 in) in diameter, the buds rupturing the surface and surrounded by hairs. Fruits spherical, white, red, or pinkish, to 10 mm (0.4 in) in diameter. Distribution: Brazil, Venezuela, Paraguay, Argentina, Peru, and Bolivia. Rhipsalis floccosa is widely ranging and variable; six sub-

Rhipsalis Venezuela

species are recognized. Subspecies floccosa has green stems, greenish white flowers, and white fruits; it occurs from northeastern to southeastern Brazil. Subspecies hohenauensis tends to have golden yellow flowers and white fruits; it occurs in eastern Paraguay, Argentina, and southern Brazil. Subspecies oreophila has almost perfectly cylindrical stem segments with no podaria, and very small flowers; it occurs in the highlands of central Bahia and northern Minas Gerais, Brazil. Subspecies pittieri tends to have more slender stem segments, and smaller flowers and fruits; it occurs in Venezuela. Subspecies pulvinigera has stem segments that are tinged red, larger flowers that may be more than 18 mm (0.7 in) in diameter, and pinkish fruits; it occurs in southeastern and southern Brazil. Subspecies tucumanensis is similar to subspecies pulvinigera but has stems without the red, and larger fruits that are red or white and to 10 mm (0.4 in) in diameter; it occurs in eastern Peru, Bolivia, and Argentina.
