Genus Mammillaria Haw . - Mammillaria - the most numerous genus of the family Cactaceae . It has 350 species and 98 varieties . The genus is divided into 3 sections hydor-hilum - with watery juice, galaktos-chylos - with milky juice and hydro sub-chymos, whose sap is available only in the central vessels . Depending on the shape of the nipple, stem and thorns, and quantities of flowers and other symptoms generally fall into these sections na sub groups and subgroups. Appearance Mammillaria, their flowers,spines and pubescence unusually varied . A distinctive feature of the genus is the lack of ribs instead of which stem of the plant is covered with papillae, and the special structure of the areola: it is divided into two parts - one carrying the spikes, is at the end of the papilla, the other - and vegetative - is in aksile (depression between papillae) . The flowers appear from last year's axilla around the top . After flowering, the fruit is formed immediately, it gradually emerges from the axilla . Plant of the genus Mammillaria culture mostly unpretentious . In the summer they need moisture and the sun (with shading from strong heat), in the winter - cold and dry content at + 8, + 10 ° . Some authors (Pazhoutet al. . ) identify groups Mammillaria the general background that creates a coating of stem pubescence . very beautiful white (M . bocasana, M . kandnda, M . plumosa and M . hahniana) and yellow Mamillaria (M . elongata, especially the kind of Stella-aurate, M . Pringles, M . goal-ziana and others), pubescence which hairs, spines and bristles often completelycloses papillae on the stem, and looks very impressive. White Mamillaria grow in mountainous areas of central and northern Mexico on limestone and chalk cliffs . They no longer need other cacti in the light of the sun and require supplements to the soil lime .     ,
