Rebutia muscula gets its name from the genus 'Rebutia', known for small, globular cacti with vibrant flowers. The species name 'muscula' is likely derived from Latin, alluding to the robust, muscular appearance of this small cactus. It reflects the plant's compact and rounded form, which is characteristic of many Rebutia species.

Technical Description of Plant
Rebutia muscula is a small, clustering cactus that forms tight mounds of spherical to slightly elongated stems. These stems are covered in small, fine spines that can range in color from white to light yellow, giving the plant a soft, fuzzy appearance. This species is particularly admired for its large, bright flowers that bloom in spring and early summer. The flowers are usually orange, red, or pink, providing a striking contrast to the green or bluish-green body of the cactus.

Origin of Plant
Rebutia muscula is native to the mountainous regions of Bolivia and Argentina. It typically grows in high-altitude, rocky areas, which has led to its adaptations for water conservation and resistance to fluctuating temperatures.

Conservation Status
Rebutia muscula does not have a specific conservation status. However, habitat loss and over-collection can pose threats to wild populations of Rebutia species, emphasizing the importance of conservation efforts.

Care instructions
Rebutia muscula requires well-draining soil, ideally a cactus mix. It thrives in bright, indirect light but can tolerate some direct sunlight. Water moderately during the growing season, allowing the soil to dry out completely between waterings. Reduce watering in winter to prevent root rot. This cactus is not frost-tolerant and should be protected from freezing temperatures. It is generally pest-resistant but should be inspected regularly for any signs of infestation. Pruning is rarely needed but can be done to remove any dead or damaged parts of the plant.
