Description
Turbinicarpus pseudopectinatus is a dwarf cactus with a globular stem covered with hatchet-shaped tubercles that bear linear areoles. The stem grows up to 1.2 inches (3 cm) tall and up to 1.6 inches (4 cm) in diameter. It has about 50 tiny white radial spines per areole spread out horizontally in a comb-like arrangement. Flowers are white to bright pink with darker magenta or reddish-brown mid-veins.

Hardiness
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Turbinicarpus prefer to be in a well-ventilated position in full sun to maintain a good body color and spinal development.
When it comes to watering, the golden rule is "never water when the compost is still damp." This is the one error that will certainly kill any plant! Watering should commence in the spring, late March to early April, depending upon the weather conditions at the time. The plants should initially be given a light spray to encourage them to grow.
These cacti can withstand high summer temperatures and benefit, providing good ventilation. Do not be tempted to overcrowd the plants. They will be far happier with a bit of space to allow the air to circulate. Winter temperatures can be set as low at 44-46 °F (7-8 °C), and providing the plants are kept dry, and the humidity levels are also kept low by good ventilation on bright days.
