Fresh seed of Hoodia gordonii available here:
 
Hoodia gordonii is a member of a large subfamily Apocynaceae of Stapelia like plants. The plants are eaten by the Bushmen during long hunting expeditions to suppress hunger and thirst, although other Hoodia species that lack the bitter taste are preferred.

Synonyms of Hoodia gordonii include Bitter Ghaap and Jakkals Ghaap. The plants are widely distributed in the dry desert-like Great Karoo, Northern Cape, Namibia and Botswana.

Hoodia gordonii can be grown from seed and cuttings. The seed germinates readily, but as is the case with so many other members of the genus, seedlings and indeed adult plants can die easily from rot.

Pleiospilos bolusii is a small succulent desert plant endemic to the Eastern Cape in South Africa.

Other synonyms include "Liver Plant".

Although the plants are widespread in the southern parts of the Eastern Cape and Western Cape, Euphorbia tridentata is by no means common. Scattered colonies of the plants appear often many kilometers apart.

Some isolated plants of Euphorbia tridentata have been found growing in the desert- like clayey plains south west of Willowore, near rocky hilltops in the De Rust area, among pebbly grassland near Heidelberg etc.

Propagation is from seed or cuttings.

Aloe pearsonii is a medium to large growing Aloe from the extremely hot and dry northern Richtersveld and southern Namibian desert. The plants belong to the group of creeping Aloes and can form considerably dense hedges. The chemical compounds in their leaves are similar to the others in the group confirming the relationship. Their distribution is rather localized around Hellskloof an Aloe pearsonii can be regarded as endangered.

The flower colour varies from red to yellow and different shades of both colors.

Cultivation is more difficult then some other Aloes and Aloe pearsonii should be planted in an elevated rockery with good drainage and watered sparingly. A good watering every now and then with enough time in between for the soil to dry out should be optimal.

Aloe pearsonii is grown from seed or cuttings.
