Krainz’ crown cactus (Rebutia minuscula)
Description
Rebutia minuscula is a species of cactus from northern Argentina. It is the type species of the genus RebutiaThe 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. They are red, up to 4 cm (1.6 in) long Other sources include species such as R. marsoneri with yellow to orange flowersin R. minuscula giving the species a much broader range of flower colour.
