Etymology:
The
genus name
"Eriosyce"
derives from the Greek words “Erion (εριον)”
meaning “wool” and “Sykos” meaning “fig
(a fruit)” .
(The genus name implies: “woolly
fruits”).
The
species name
“napina”
derives from the
Latin
“napus” meaning
"turnip”
plus the adjective suffix for nouns "inus"
meaning "belonging to or resembling"
(The specific name implies:
“resembling a turnip”)
The
subspecies epithet "lembckey"
was named in honour of "Hans
Lembcke" Germany expert and
author about Chilean species of cacti.
The
variety epithet
"duripulpa"
derives
from the
Latin adjective
“durus” meaning
"hard,
firm, vigorous”
and "pulpa" meaning "soft
part of the body, pulp" (The specific
name implies: “hard pulped”)

Cultivation:
It needs a deep pot with very good
drainage to accommodate its
tap root.
It
is
susceptible
to
over-watering.
Sometimes it is
grafted to avoid
root
rot problems.
Keep dry in
winter.
Suited for
airy exposures. It likes
full sun;
and can
tolerate
light shade.
It likes warmth (recommended minimum winter temperature: 5° C) But a
plant kept perfectly dry can easily
survive
at winter night-time
temperatures below 0° C (in our greenhouse no damage at -10° C for a few
hours in the winter of 2002-2003)
Pests &
diseases: E.
napina is especially
prone to rot, therefore,
underpot in a
smaller container filled with very
porous compost.
Propagation: Seeds or graft. Seeds can be sown in
the spring or summer. The seedlings should not be disturbed until
they are well rooted, after which they can be planted separately in
small pots.
