Rebutia

The genus Rebutia (Rebutia) unites more than 20 species of small cacti with slightly flattened and rounded stems, with characteristic low tubercles arranged in a spiral, and numerous short spines. They form many offspring, are characterized by abundant flowering. Numerous, long-lasting tubular flowers in most species are red or orange, with yellow anthers, and rebutia with white or yellow flowers are also found. They do not develop at the top, but at the base or sides of the stem. Later, berries are formed in place of the flowers. The white-flowered rebutia (Rebutia albiflora) is distinguished by white spines. White or pinkish-white flowers appear in summer. R. aureiflora has yellowish-white spines and golden-yellow flowers that appear in April and May. The golden-prickled rebucia (R. chrysacantha, or R. senilis) grows up to 8-10 cm in height and width; the bristly spines are white. Red flowers bloom in spring. The flowers of the subspecies R. C. lilacinorosea have an extremely intense pink color, which effectively contrasts with the yellow anthers. In the Feibrig rebution (R. fiebrigii, or R. muscula) spines are white. In late spring, funnel-shaped flowers appear, bright orange or red in color. The stems of R. marsoneri reach a height of 5 cm and a diameter of 10 cm. The spines are white or brown, and the flowers that bloom in spring are golden yellow. Rebutsia snizhnaya (R. nivea) is densely covered with white spines, and flowers appear in spring, colored in tones from bright orange to red.
