numerous spines and the small-sized pale yellow flowers.

and are very showy.
The red purple stigma emphasize the yellow of the petals.

Description: Usually solitary (in the standard
form), or branching.
NOTE:
Notocactus langsdorfii,
together with the subordinated
taxa ('leprosorum', 'longispinum',
'pulvinatus', ediewarasii', 'multiceps' and
'prolifer'), form a group of
very similar and controversial southern Brasilian plants bearing small
flowers and strong spination.
Stem: Bright or dark green, globose to short cylindrical. The
apex is depressed and filled with whitish-grey wool.
Ribs: Well marked and sharp, with scarcely prominent chinned
tubercles. The crest of the ribs typically take on a purple red hue in
full sun.
Areoles: Well spaced, woolly, recessed .
Spines: Several, yellowish, strong, about 20-25 mm long, spreading
or curved down and backward.
Flowers: Small, lemon yellow with glossy shining petals, up to about
2-3 cm in diameter, standing near the top,
and decorated with a red pistil which emphasizes the yellow of the petals.
The buds are tomentose.
Blooming season: They bloom annually around June-July.
NOTE: All species of genera
Notocactus, Wigginsia and Malacocarpus
have recently been transferred to genus Parodia, so the
names of several plants previously accepted are now all synonyms of
Parodia langsdorfii.

Cultivation:
It is easy to grow. The plants like a warm bright location, and do great in
partial shade. Avoid full sun. 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. Keep above 0°C
and rather dry in winter; they rot easily if the substrate is wet and cold,
and tend to lose their roots in winter.
Propagation: Seeds
