Description: Parodia oxycostataSN|20466]]glaucina|SN|20473]] (a.k.a. Notocactus glaucinusSN|20473]]SN|20473]]) is a local form of the wide ranging and very variable Parodia oxycostataSN|20466]]SN|20466]] distinguished from the latter by the waxy coating on the epidermis (From Latin "glaucinus" = "With a waxy bloom") and pink fruits. The differences with other Parodia oxycostataSN|20466]]SN|20466]] are in reality very minimal and most botanist agree on the fact that both should all be included in the Parodia oxycostataSN|20466]], and the two plants are not readily distinguishable, if not for the geographical provenance. The "glaucina" is merely one of the several forms regarded as a mere ecotype with size or colour modified by more humid or arid conditions and merging into typical plants in cultivation. However similar plants occurs at random elsewhere.
Habit: Plants solitary, only rarely offsetting into small clusters in time. The stems are flattened globular and will bear several glossy yellow flowers around the very woolly stem apex in mid summer.
Stem: Flattened globose to globose, grey-green, to 9 cm in diameter.
Ribs: 6-12, acute, with shallow chinlike protrusions between the areoles.
Areoles: Round, white at first, later grey, then naked.
Spines: Reddish brown to bright yellow, becoming lighter with age, flattened, twisted.
Central spine: 1, pointing downward, upto 20 mm long.
Radial spines: Usually only 2, one pointing downward, 16-25 mm long, sometimes with as many as 8 additional small spines to 6 mm long.
Flowers: Borne several at a time apically, bell-fummel-shaped to sometimes urn shaped, yellow, to 1 cm long and 4,5 cm in diameter; pericarpels and floral tubes with scales, white wool, and reddish brown bristles in clusters. Stigma red.
Blooming season: Flowering occurs in summer through early fall and will bloom several times during warm weather.
Fruits: With yellowish grey wool and reddish brown bristles, 2,5-2,7 cm long.
Seeds: Helmet shaped, shiny black.

Cultivation and Propagation: They like a warm bright location, does great in partial shade avoid full sun. During winter's rest period they should be dry and cool. It is best to avoid any frost but during the winter the temperature can be as low as 2° C without any harm so long as the compost is very dry, they like only a short winter's rest. If the soil is allowed to be dry for too long root loss could follow but equally the same result would occur if the plants are both wet and cold. Cold spots can mar its epidermis in cold damp conditions. They need good drainage and prefer a neutral to slightly acidic compost with plenty of extra grit. Water and feed during the summer. Best if watered with rain water and given an occasional tonic of sequestrated iron.
Propagation: Usually by seeds as it seldom produces offsets.
