Description: Astrophytum myriostigma (many dots) is a spineless cactus. Quadrangular to almost spherical, the plants become shortly columnar with age. It is covered with many minute white hairy scales that give it a characteristic chalk-white or silvery-grey appearance. A transverse section of the stem reveals a perfect star shaped form giving the plant the appearance of a bishop's mitre (hence the common name Bishop's cap). The stems are smooth and can be over 90 cm tall and 5-10 (-20) cm in diameter.
Blooming season: A. myriostigma flowers independently of day length, flowering intermittently throughout the warm months from the end of winter to the start of autumn.
