Stemcylindrical, kustyaschiysya; aksily woolly (especially in the flowering) on the areola 18 - 20 white radial spines and 4 - 5 golden-yellow at the base of the thickened central spines; flowers red . The species has two varieties: V . albescens, v . bogoten-sis, the first of which with the top, richly covered with white hair, especially beautiful . 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 milky juice there is only a central vessels . Depending on the shape of the nipples, studs, and the stem, as well as quantities of flowers andother symptoms generally fall into these sections na sub groups and subgroups. Appearance Mammillaria, their flowers, thorns 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 isat the end of the papilla, the other - and vegetative - is in aksile (the depression between the papillae) .

Some authors (Pazhout, etc. . . ) 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 speciesStella-aurate, M . Pringles, M . tselziana and others), pubescence which hairs, spines and bristles often completely covers the buds 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 requiresoil additives lime .
