funnel-shaped magenta
with lighter edges of

Description: Body usually
solitary,
globose. Hardly
offsetting in cultivation.
Stem:
Spherical or somewhat
conical, rounded above;
apex rather deeply sunken, but fully hidden by the snow-white, dense
wool; blue-green, 6-8 (10) cm high and 6-8 cm in diameter.
Ribs fully arranged in
tubercles, from 13 to 21, rather dense
spirals,
rhombic or
sub-quadrangular,
conical; the top somewhat compressed from the sides, with sharp
upper and lower edges. The
seedlings tend to become quite
cylindrical.
Roots:
Carrot-shaped
Flower: Flower broadly
funnel-shaped.
Tepals linear, blunt, green with violet edge; inner linear -
lanceolate, pointed, magenta with lighter edges of petals. Length
and diameter of the flower 2-2.5 cm. White
Filaments; the
Anthers are dark chrome yellow. The white
style towers over them with 6 recurved
lobes.
Phenology:
Blossoming time: summer
Fruit: Fruits, urn-shaped, are 12 mm long.

seedling with typical
plumose spine. |
2-year-old spines |

Juvenile spines transform in a young
seedling
Spines (in
adult plant): Close-packed,
radial, mostly 12,
awl-shaped, very sharp, sticking
out up to 17 mm, snow-white,
translucent, young almost glass-like, black tipped.
Central spines 1, much longer (up to 30 mm), somewhat stronger, white, but
at the top and further down, dark brown to black.
Later they become grey,
and the radial spines radiate horizontally, almost
comb-like.
Juvenile spine:
Plumose, soft, flexible, not pungent.
During the first year
near the
base thin feathery
hairs begin to form. Often the spine is densely covered, with
hairs up to its tip. Spines of
two-year-old
seedlings (see figure) differ only in being longer and
more ragged. There are no
central spines; all are
radial.

Basionym:
Thelocactus beguinii

Distribution: Northeast Mexico to central Mexico, Zacatecas, San Luis Potosí, Coahuila to Hidalgo.
Habitat: It grows in scattered
colonies, on different mountains,
on warm
steppes, and in pine forests or bushes, at altitudes
of around
1900-2100 m., on
lime with a high content of
organic parts and a slightly
basic pH. Localities are difficult to reach, and the main danger
comes from
fires.
