Description
Pseudolithos migiurtinus is a rare succulent with a usually solitary stem that grows up to 3.6 inches (9 cm) tall and up to 2.4 inches (6 cm) in diameter. The stem is initially spherical but eventually becomes more egg-shaped or even columnar as the plant ages. The stem bear four rows of small truncated stems, from which the flower buds emerge. Flowers are small, starfish-shaped, and deep maroon.

Hardiness
USDA hardiness zone 11a to 11b: from 40 °F (+4.4 °C) to 50 °F (+10 °C).
How to Grow and Care
Stapeliads are relatively easy to grow. However, they should be treated as an outdoor plant as they will easily rot indoors and cannot flower without exposure to outdoor temperature fluctuations. They should be grown under cover so that watering can be controlled. They require a reasonable amount of sunlight to promote flowering and maintain a well-shaped plant. Very shady positions will produce very poor flowering. Stapeliads come from climates where they survive extremely high temperatures in the summer months, so most growth is in spring and autumn, with flowering in autumn when the weather starts to cool down. Water in moderation when needed in the growing season, making sure soil is fairly dried out between waterings. Do not water between November 1 and March 1. Fertilize lightly, if at all, to prevent overly lush and weak stems.
The easiest and best way to propagate Stapeliads is from stem cuttings which can be taken virtually throughout the year. Seed is also a method of propagation.
