Types are based on several physical traits, i.e. crenate
or dentated phylloclades & symmetrical or asymmetrical
flowers. Other traits are pollen color, color of the
stigmatic tube and ridging or smoothness of the ovary
B – Buckleyi Type, which can be an interspecific hybrid
of S. russelliana and S. truncata. It can also be any cultivar
showing crenate phylloclades and symmetrical
to near symmetrical flowers similar to S. russelliana
and three to four ridged ovaries and fruit.
BT – Mainly Buckleyi traits or russelliana traits. The BT
type have slightly asymmetrical to very zygomorphic
flower form with pinkish or greyish pollen color (as
opposed to yellow with the B type). Ovary and fruit
generally have 3–4 significant ridges similar to S. russelliana
or S. Å~ buckleyi.
EP – S. Å~ eprica, which is S. russelliana Å~ S. orssichiana.
The term S. Å~ eprica was named after the E.P.R.I.C.
N – Hybrids and cultivars which doesn’t fit to one of
the other types.
O – Exotica or S. Å~ exotica are an interspecies cross of
Schlumbergera opuntioides Å~ Schlumbergera truncata
or S. Å~ buckleyi. The segmented sections are not flat
phylloclades but are 3-dimensional having 3–4 sides.
Q – Queens or S. Å~ reginae are an interspecies cross of
S. orssichiana Å~ Truncata type cultivar or species.
Queens have larger, longer phylloclades with significantly
long dentation. Flowers are larger than a S.
truncata type with a short, slightly curved flower
tube. Some can have more than one blooming season.
T – Schlumbergera species exhibiting marginal and
apex dentations on their phylloclades, upright growth
habit, and asymmetrical flower form. The majority of
hybrids exhibit these traits.
TB – More Truncata characteristics such as dentated,
asymmetrical flower form, yellow pollen and fruit
with faint ridges or smooth.
