Notocactus magnifica | Parodia magnifica

Parodia magnifica is an attractive species with globular to barrel-shaped, blue green stems which may also bear a light dusting of a whitish, waxy bloom. The stems bear 11 to 15 acute ribs which produce areoles and rusty-golden bristle-like spines along their edges. Most authorities indicate that the stems will reach a diameter to about 6 inches, but I have seen plants in cultivation which have exceeded this size slightly. 2 inch satiny, butter yellow flowers are intermittently produced at the summit of the stem through the summer months. 

Pot sizes are 2.5", 3.0" and 3.5", First picture is just for reference, you will receive a (bare rooted, with some soil) similar plant shown in picture 2,3 and 4.

"Sizes are approximate" every plant is slightly different then others and due to your screen setting and different screen type.
