Description: Conophytum obcordellum ssp. stenandrtun (L.Bolus) S.A.Hammer 1993 (Conophytum stenandrum L.Bolus 1961) has distinctively metallic greysh-green bodies with few branched fine lines and dots not extending down the sides.
Habit: It is sparsely branched.
Bodies (paired leaves): Rather small, pancake-shaped, convex at the apex, less than 1 cm in diameter with a small growing cleft that doesn't reach right across the body.
Colours: Silvery-green or variably suffused with red, glabrous, marked with fine teardrop-shaped lines and dots, these often raised and reddish, and which often turn a beautiful bright ruby-red during the resting period. The unspotted sides are pink to a deep dark red.
Flowers: Never paired, pale creamy-yellow often tipped pink with a paler yellow centre. The thin petals form an almost star-like, spidery structure, they are faintly scented and very showy. Stamens 15-40, partially exserted, anthers slender (hence the name). Style minute with 4-6 stigmas 3 mm long.
Blooming season: Blooms mostly in autumn (in cultivation in Europe August-November). The flowers are numerous and open at night.
Fruits: 4-5 locular hygrochastic capsules.

The gallery now contains thousands of pictures, however it is possible to do even more. We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Read More...
Cultivation and Propagation: Conophytum obcordellum subs. stenandrum is easy to grow. These plants grow on winter rain and head for summer dormancy. More or less dormant in summer. The plant requires little water; otherwise its epidermis breaks (resulting in unsightly scars). Water throughout the year although minimally in summer, (only when the plant starts shrivelling), but it will generally grow even in summer if given water. Water regularly in winter after the previous year's leaves have dried up. Requires good drainage. Keep cool and shaded from hot sun in mid-summer; it needs full sun or light shade in the other seasons. Hardy to -2°C. Ensure a very good ventilation. Avoid to repot frequently. This plant may stay in the same pot for many years. Plants grown in larger containers have frequently relatively poor flowers. It might improve when the plants are given their own, small individual pots.
Propagation: It can be reproduced both by cuttings and seeds. Take the cutting from a grown-up mother plant. Each cutting must contain one or more heads, along with a fraction of root.
