Etymology: Named after the Germany botanist Dr W.G. Herter .
Notes: Recently, the genus Notocactus has undergone name changes, and as a
result, all Notocactus are now included in the genus
At this time, it is believed that Notocactus and Parodias have
similar characteristics that they should be placed in one
Description: Notocactus herteri is a large growing plant, usually
solitary or slowly branching from the base.
Stem: Almost spherical that can became shortly cylindrical when old, up
to 15 cm in diameter and tall with a shiny deep green skin, the apex is
depressed, white-grayish and woolly
Ribs: About 22 well defined and spiraling.
Tubercles: Well pronounced, chinned.
Radial spines: 8-11 thin, flexible and acicular up to 20 mm long,
whitish with a brownish-red tip.
Central spines: Stouter (20-30 cm long), subulated, brown-reddish,
grayish when old.
Areoles: Deeply seated within a depression between the chins, woolly
that become bare when older.

extremity. Filaments and style greenish/yellow, anthers golden yellow,
stigma 10 lobed, pinkish with the a white extremity.
Blooming season: July through September.
Cultivation: Suitable for the home or a greenhouse,
During winter's rest period they should be dry and cool, it is frost resistant to -4°C but
thrives best with additional heat, 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, rot easily if the substrate is
wet and cold. Prefers filtered bright light with ample airflow. Will
enjoy regular water in summer. Best if watered with
rain water, an acid compost and iron feed help to delay the onset
of basal corking. A well grown plant is a fresh glossy grass- green,
contrasting with reddish spines.
Propagation: Usually by seeds as it seldom
