Xerophyte

Habit

It is a low-growing clustering cactus that may forms clumps of many heads, in habitat the plant retract almost completely below soil level during time of drought .

Central Spines

None.

Description

Rebutia canigueraliiSN|5130]]SN|5130]] var. callecallensis is one of the innumerable local form of the very variable Rebutia canigueraliiSN|5130]]SN|5130]] with tiny clustering stems short, pectinate adpressed, bright spines and outstanding bicoloured yellow-red blooms.

Phenology

Flowers are produced in late spring and remain open for three or four days.

Roots

Conical.

Flowers

From the basal part of the stem, 20 - 50 mm long, 35 - 50 mm wide nearly all bi-coloured orange or red, with yellow throats, some with shimmering blue tips of the petals. Some of these flowers appear almost three-coloured, which of course makes them particularly attractive. However, there are small populations of plants with darker, reddish shaded epidermis with almost pure red flowers . Elsewhere, there are only yellow to yellow-orange-colored flowers or purple flowers with yellow throat, a combination of colours which is rarely seen in this manner from any other Sulcorebutia.

Ribs

With slightly raised tubercles (about 3-4 mm wide) . In older plants tubercles are arranged in up to 8-13 spiral line merging in the apex.

Stem

Rapidly offsetting from the base, very small, typically light-green or (rarely) dark purple. A characteristic of this species is that the offsets develop roots while still attached to the mother. Individual stems 1-2 cm talland in diameter (or a little more in cultivation).

Radial Spines

11 to 14, fine, bristly, 1,5-2 (or more) mm long tight, pectinate, pointing diagonally and downward, that recurve and hug the tubercles so as not to be felt. Straw to amber with darker bases. Not interlaced.

Fruits

Dark brownish red approx 4-5 mm wide.

Areoles

2-3 mm long, narrow with short white felt.
