Taxonomy
Notocactus uebelmannianusSN|19998]]SN|19998]] Buining, Kakt. and. Sukk. 19(9)
Flowers
Small about 5 cm in diameter, short funnel-form, shiny, wine red to deep magenta of various tones, or pure yellow (Parodia werneriSN|19997]]SN|19997]] f. flaviflora). Both purple and yellow flower colours can exist side by side in some populations and the yellow being the most abundant. Therefore the more commercial but less representative purple flowered form was made the species and the more typical yellow flowered the variety.

Spring to early summer, once it reaches about 7 cm in diameter if kept well it will flower every year.
Ribs
12-16, flat, round, more ore less chinlike.
Stem
Shiny dark green, globular or short/squatty up to 12 cm tall and 17 cm in diameter.
Radial Spines
About 6 spider-like, 10 to 30 mm long, appressed against the stem body, one pointing downward, unequal, white to greyish.
