Until a few years ago, only few clones of secured plant material of botanical species were available. Since these are well known and documented, they will be briefly introduced here.
Schlumbergera orssichiana – (O)
Dolly K3 – USA. Jochen Bockemühl, named by Jochen Bockemühl and Ruud Tropper, 2016. (Popponesett KS22 × Jochen KS21W24). Dolly Kölli made the initial cross. The seed was germinated by Jochen Bockemühl in May 2014. When the seedling was one year old, it was raised by Ruud Tropper. Ref.: EPIG 77: 9–11. (2016).
Eckhard KS25 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
Highwood KS22W24 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
Jochen KS21W24 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
Mashpee KS21W5 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
New Seabury KS21W2 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
Popponesset KS22 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
Quashnet KS30 – USA. Dolly Kölli. (Wild Type I × Wild Type II).
Unnamed K1 – USA. Jochen Bockemühl. (Popponesset KS22 × Jochen KS21W24).
Unnamed K2 – USA. Jochen Bockemühl. (Popponesset KS22 × Jochen KS21W24).
Wild Type I – Brazil. Large, 9 cm by 9 cm slightly zygomorphic flowers have white center that suffuses to carmine tips, opening very wide. Color varies depending on the time of year bloom occurs. The short tube is white, with white filaments, deep yellow anthers and magenta style having 6–8 stigma lobes. Pericarpels are light green, c. 1.2 cm long and 5–6 angled, differing from the smooth pericarpels of S. truncata. Ripe fruit is yellow-green to white, whereas S. truncata has pink to reddish ripe fruit. Growth is close to S. truncata. Growth habit is very pendant with large, wavy phylloclades 5–7.5 cm long by 3.2–4.5 cm wide, with margins having 2–3 sharply pointed, sometimes curved dentations. Often an extra dentation appears near the apex of a segment. This trait is also evident in S. orssichiana hybrids. Distribution: Countess Beatrix Orssich received the plants from an orchid collector without precise locality. It was said that they were collected at the Morro dos Três Picos in the state of Rio de Janeiro. Mrs Orssich supplied the initial two wild forms from Brazil. These initial plants were grafted once they arrived in Europe. It is believed the rootstock was virused, which is where the issue of viral infection originated in the early specimens. Fortunately, the two forms were crossed and virus free seedlings produced.
Wild Type II – Brazil. Slightly smaller flower size. Coloration is the same as Wild Form I. Phylloclades are also similar differing only in being slightly smaller. All other characteristics identical.
Wild Type III – Probably same as Wild Type I. Heavily virused, smaller than Wild Type I. Could not be hybridized with Wild Type I.
Schlumbergera russelliana – (R)
Bachthalers Wildform – Brazil, PSNO above 1800 m. PSNO – Parque Nacional da Serra dos Orgãos (Organ Mountains National Park). Collected by Dr. Esser. Perianth is oblique suggesting this is an intermediate form (Horobin). There is said to be two forms of this russelliana. Ref.: McM&H 1995: 34.
Bonn 4672 – Brazil. Bonn Botanical Garden, Germany.
Ehlers Form – Teresópolis, Brazil. Flower is pendant, small, solid fuchsia pink with recurve petals. Fruit is 4-angled, green and spherical. Phylloclades are very small and thick with two areoles per side. The base of the phylloclade is narrow and the apex is wide giving a triangular appearance. Also known as Small Form and Mrs Ehlers Small Form. Found in a deep ravine. May exist in two forms, one being larger. Ref.: McM&H 1995: 36.
H Form (Heidelberg Form) – Brazil. Heidelberg Botanical Garden, Germany by a Mr Pauli, origin unknown. Nice healthy compact plant. Heidelberg 33160. Phylloclades are very wide and square in shape. Usually one, but sometimes two areoles per side. This form no longer exists in the Heidelberg Botanical Gardens.
Hunt 6484 – Abrigo II, Brazil, above 1500–1600 m. Flower color described by Horobin as RHS 71B, 5.8 × 3.5 cm with back petals 5 cm Stigma exerted 3 mm, anthers and pollen pink. Said to still be available. However, what is currently advertised does not match. Thomas H. Boyle used this species to create his S. × buckleyi remakes: Albert Loefgren and George Gardner. It is reported that Boyle also lost Hunt 6484. Collected by D. Hunt, Aug 03, 1966. Preserved at Kew Gardens, which distributed cuttings. Described as epiphytic growing in trees near a stream. Ref.: McM&H 1995: 34.
Huntington No. 34533 – Brazil, PSNO at 2073 m (6800 feet) a few hundred feet below Pico de Açu. PSNO – Parque Nacional da Serra dos Orgãos (Organ Mountains National Park). Flower color is a uniform RHS 67B. Flower length 5 × 3.7 cm, corolla is regular with seven perianth segments 5 mm broad. Tube is self-colored, no ring, with stamens holding pink pollen. Style is 4.5 cm, stigma is rounded RHS 67A, pericarpel is greenish brown with four angles or ridges. Segments are small and slender. Not hardy. Collected by Dr. Fowlie in an orchid-hunting expedition. This specimen languished at Huntington Gardens. Said to be similar to the JFH Clone II collected in 1981. McMillan grafted a cutting in 1983, which flowered in March 1987. Ref.: McM&H 1995: 34.
JFH Clone I – Brazil. Flower color RHS 67C. Flower length 5 cm, tube 3 cm Anthers and pollen are deep pink, style white at intersection to the ovary, then magenta from halfway up. Fruit is 4–5-angled or ridged and ripens greenish-yellow. Dark brown seeds are larger than S. × buckleyi or S. truncata. Stem segments are 1–3 cm × 1–1.5 cm, bright green with one, occasionally two areoles on each side. Growth habit branched and pendant. Collected by Hooker in 1839. Described by Tjaden in 1966 and presumed lost. Later rediscovered by Horobin in 1983 in an estate garden greenhouse in Sussex, England. Ref.: McM&H 1995: 34 & 36.
JFH Clone II – Brazil, PSNO at 2000 m. Flower is clear pink with fruit and seed similar to JHF Clone I. The differences are the stamens, style and pollen are a deep magenta. The style is white from the ovary and the color starts halfway up. Stigma shape differs by not being as knob-shaped and more like S. × buckleyi. Collected by Dr. G. Brasil in 1981 and discovered 1983 in an estate garden greenhouse in Sussex, England. Ref.: McM&H 1995: 36.
South of Nova Friburgo Form – Brazil. Flower is solid fuchsia pink, lighter on the tube. Flower shape is symmetrical with recurve petals. Phylloclades are crenate and Buckleyi in form. An easier form to grow than many of the other clones. Russellianas are challenging at best and difficult to keep over time.
VDL – Vale da Luva, PSNO (Organ Mountains National Park), Brazil. Small, narrow phylloclades with two areoles per side.

Branco – Brazil. (NS) White flowered, possibly the same as S. truncata delicata. Ref.: McM&H 1995: 104.
Espirito Santo Domingo – Brazil. Does not occur in Espírito Santo state. The name may have originated from Roberto Kautsky who lived in Domingos Martins, Espírito Santo. Flower is a carmine-pink shade.
