Rebutia minuscula
Also called Red Crown Cactus, Violet Crown Cactus
Rebutia minuscula is a small globe-shaped cactus from northern Argentina and Bolivia that forms dense clusters and produces bright flowers from the base of the plant. It is grown as a compact container plant and needs bright light, sharp drainage and a dry rest in winter.
Rebutia minuscula is a species of cactus from South America found in northern Argentina and Bolivia. It is the type species of the genus Rebutia. As its synonym Rebutia senilis it has gained the Royal Horticultural Society's Award of Garden Merit. Its cultivars 'Krainziana', 'Marsoneri' and 'Violaciflora' are also listed as having gained the Award of Garden Merit.
The status of the species of Rebutia is currently uncertain; indeed the genus as defined by Anderson (2001) has been shown to be polyphyletic. Anderson describes R. minuscula as consisting of globe-shaped stems with a diameter of up to 5 cm (2 in), forming large clusters. The stem has 16–20 ribs with small but distinct tubercles ("bumps"). Each areole produces 25–30 fine whitish spines, 1–3 mm (0.0–0.1 in) long. As in other species of Rebutia, the flowers are not produced at the top of the stem, but from around the base.
