Schlumbergera kautskyi – (K). Brazil (Espírito Santo, Minas Gerais), in altitudes above 1200 m. Phylloclades flattened, 4 cm long and 2.5 cm wide, apical and marginal with forward pointing teeth. Flowers with a well-developed perianth-tube, zygomorphic, up to 5 cm long, fuchsia-pink, self-fertile. Fruits elongated, greenish, ribbed. Flowering period in northern hemisphere: September to November.
Schlumbergera lutea subsp. lutea – Brazil (Rio do Janeiro), in altitudes between 800 and 1500 m elevation. Phylloclades flattened, 2.5 cm long and 1 cm wide, crenate in form. Flowers broadly funnel form, brilliant yellow, self-sterile. Fruits spherical, greenish, angled. Flowering period in northern hemisphere: March to May.
Schlumbergera lutea subsp. bradei – Brazil (Rio do Janeiro), in areas above 800 m elevation. Phylloclades flattened, 1.5 cm long and 1 cm wide, narrower than subsp. lutea, club-shaped. Flowers broadly funnel form, brilliant yellow, self-sterile. Fruits spherical, greenish, angled. Flowering period in northern hemisphere: March to May.
Schlumbergera microsphaerica – (M). Brazil (Minas Gerais, Rio de Janeiro), known only from two disjunct locations in the states of Minas Gerais and Rio de Janeiro above 2400 m elevation. Phylloclades cylindrical, 4 cm long and 0.5 cm diameter, with few, spined areoles. Flowers with a well-developed perianth-tube, zygomorphic, up to 4 cm long, solid fuchsia pink with little recurve, self-fertile. Fruits spherical, greenish, angled. Flowering period in northern hemisphere: April.
Schlumbergera opuntioides – (Op). Brazil (Minas Gerais, Rio de Janeiro, São Paulo) in altitudes between 1600 and 2300 m elevation. Phylloclades flattened, pad-like similar to an Opuntia, 7 cm long and 3 cm wide, with some areoles and spines on it. Flowers with a well-developed perianth-tube, zygomorphic, up to 6 cm long, solid fuchsia pink with little recurve, self-sterile. Fruits spherical, greenish, angled. Flowering period in northern hemisphere: February/March.
Schlumbergera orssichiana – (O). Brazil. (Rio de Janeiro). Phylloclades flattened, 7.5 cm long and 4.5 cm wide, apical and marginal with forward pointing teeth. Flowers with a well-developed perianth-tube, slightly zygomorphic, up to 9 cm long, pinkish, self-sterile. Fruits elongated, yellow-green to crème, ribbed. Flowering period in northern hemisphere: August to November. The exact location remained unknown for a long time. Some years ago, it was rediscovered in the state of Rio de Janeiro at an altitude of about 350 m, about 70 km apart from the putative location.
Schlumbergera russelliana – (R). Brazil (Rio de Janeiro) in altitudes above 1700 m. Phylloclades flattened, 3.5 cm long and 2 cm broad, apical and marginal no teeth, with one or two areoles per side. Flowers with a well-developed perianth-tube, radially symmetrical, up to 5 cm long, pendant, solid fuchsia pink, self-sterile. Fruits spherical, greenish, ribbed. Flowering period in northern hemisphere: February to March.
Schlumbergera truncata – (T). Brazil (Rio de Janeiro), in altitudes between 250 and 1300 m elevation. Phylloclades flattened, 6 cm long and 3.5 cm wide, apical and marginal with forward pointing teeth. Flowers with a well-developed perianth-tube, zygomorphic, up to 7 cm long, white, rose, red or purple with all intermediates, self-sterile. Fruit pear-shaped; pinkish to reddish, not ribbed. Flowering period in northern hemisphere: October to November.
Rhipsalidopsis gaertneri – Brazil (Rio Grande do Sul, Santa Catarina, Paraná) in altitudes between 350 and 1300 m elevation. Phylloclades flattened, 7 cm long and 2.5 cm wide, apical with brownish bristles. Flowers broadly funnel form, radially symmetrical, up to 5 cm long, scarlet, self-fertile. Fruits flattened spherical, reddish, ribbed. Flowering period in northern hemisphere: March to May.
Rhipsalidopsis rosea – Brazil (Rio Grande do Sul, Santa Catarina, Paraná) in altitudes above 800 m elevation. Phylloclades flattened, 4 cm long and 2 cm wide, apical and marginal with fine, brown bristles. Flowers broadly funnel form, radially symmetrical, up to 4 cm long, pinkish, self-fertile. Fruits flattened spherical, yellowish, ribbed. Flowering period in northern hemisphere: March to May.
Hatiora cylindrica – Brazil. (Bahia, Minas Gerais, Rio de Janeiro, São Paulo) lithophytic or terrestric at an elevation of sea level to 1200 m. Similar to Hatiora salicornioides but with sometimes red edges. The stem segments are cylindrical and not bottle shaped like in H. salicornioides. The fruit is whitish to purple. Flowering period in northern hemisphere: January to April.
Hatiora herminiae – Brazil. (Minas Gerais (?) and São Paulo), epiphytic in the cloud forests of the Serra da Mantiqueira, at elevations from 1750–2050 m. Growth habit is erect to pendent, up to 50 cm. Cylindrical stem segments are a grey-green that can turn purple tinged in full sun, 5 cm in length and 0.5 cm in diameter. Attractive pink to violet-pink flowers have brilliant orange stigmas extending slightly past the flower apex. The 2 cm long and 2.5 cm wide flowers are self-fertile. Fruit whitish. Flowering period in northern hemisphere: January to April.
Hatiora salicornioides – Brazil. (Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná) from near sea-level to 1850 m. Erect or pendent, eventually woody, segments clavate, 1.5–5 cm × 3–5 mm, typically with neck at base and resembling inverted bottles, in some forms ±cylindric to globose. Flowers terminal or apical, up to 13 × 10 mm, yellow to orange; inner tepals erect to incurved, hiding the stamens; fruit globose, ca. 5 mm, white to pale purple. Flowering period in northern hemisphere: January to April.
