Etymology: The

which is the main centre of distribution of this plant.
The

(LA RIOJA in Argentina) to which the species is native.
The
variety name "bonnieae"
derives from the
name
of
one of the
discoverers: Mrs.
Bonnie brunkow

in
height, diameter 1,5-2,5cm. The apex
is depressed. The stems can be
deciduous in the dry season,
as
is usual for the genus
Pterocactus.
Areoles : On small tubercles, arranged in about 30 spiral
lines whit short white hairs.
Spines:
About 10,
pectinate pink-brown that turn grey, 1-1,5mm long.
Roots:
Tuberous,
10-15cm long, up to 5-15 mm
in diameter.

shining, outer
tepals
are bronze, diameter and height:
2,5 (-4) cm. Blooming time: May.
Stigma yellow with
red stylus.
Fruit:
Ovate
1,2-1, 8cm long, 0,6-1,1
cm in diameter, dark violet,
longitudinally
dehiscent. Covered by hairy scales.
Seeds: Seed black, up to 400 per fruit.
Notes: Related to L.
famatimensis, clearly distinguished from it by the narrow
neck that separates the large tuberous roots from the stem.
Cultivation:
Seedlings grow faster than other L.famatimensis.
The plant is
rot prone and needs
a mineral soil with very good drainage.
For
this reason it is usually found as a grafted plant.
