This article provides information on the succulent plant Stomatium Schwantes. The type species, though only described later, had been named with the original description of the genus. Although the presence of teeth has been given as typical of the genus, some species lack them, at least at times, and often in habitat. This is particularly obvious in the type species, Stomatium suaveolens, which differs also from many other species by developing a tumble fruit breaking off the stalk. Remarkable is also the fact that the species possesses a tube of 5 millimeter length, a value not reached by any of the other species described. The distinction against Rhinephyllum, also without covering membranes proper, remains difficult.

This article provides information on the succulent plant Tetragonia. The plant is classified as an annual to perennial with herbaceous or woody branches. Its leaves are basally often opposite, but in most of the plants alternate, petioles short to long, blades ovate to almost linear, tips often obtuse, epidermis with papillae of various shapes, often two different types, one of them elongate and hairy. Flowers are solitary, in small to bigger cymes, or in well developed, elongated cymes in which each flower bears a bract.

This section provides information on several species of the succulent plant Trianthema. Trianthema L. has annual to perennial herbs, branches are basally sometimes woody, prostrate and diffuse. Trianthema argentina has annual herbs with decumbent to erect branches. Its flowers are in rather compact cymes, perigone lobes and are papillate outside.

This article presents information on Sesuvium plant from the Sesuvioideae family. This plant is annual to perennial, prostrate to ascending herbs or shrubs with a short tap-root, sometimes rooting at the nodes. The leaves are opposite, petioles broadening basally and forming a papery sheath clasping the stem, but not stipulate, blades almost cylindrical to elliptical or obovate, epidermis with low or higher bladder cells. Flowers are solitary.

This article presents facts about the succulent plant Ruschia. The plant is erect, sometimes decumbent, even creeping or caespitose shrubs. Leaves are mostly longer than wide, rarely reduced, trigonous to triangular, often dentate, epidermis flat to papillate. Petals are often in five groups, purple to white, filamentous staminodes surrounding the stamens in a central cone, nectary with a lophomorphic ring. With more than 400 names available at species level, this is the one of the biggest genera in the family Aizoaceae. Since the original description of 18 species in the genus, no revision down to species level has been published.

This article presents taxonomic information on the succulent plant genus Pleiospilos (P.) of the family Ruschioideae. Generally, Pleiospilos has compact, single heads to caespitose. The leaves have trigonomous to semi-globular, humped at the back and often laterally expanded. Its flowers have one to three yellow petals. The fruits are robust and dark brown. Species assigned under the genus are P. simulans, P. bolusii and P. nelii.

This article offers information on Oscularia, a succulent plant characterized with erect or spreading shrubs. Its leaves are trigonous with convex sides and very light grey from a distinct layer of crystal sand in the outer epidermal wall and a thick wax cover of densely placed platelets petering out into narrow structures sometimes forming threads, margins and keel in several species dentate. The plant grows mostly in rocky places, often in crevices inhabiting shady niches.

This article presents information on succulent plant genus Malephora Ruschioideae. Its leaves are trigonous to terete and flowers are solitary or in cymes. The genus grows in loamy, deep soil, requiring a high amount of moisture. Malephora is the only weedy genus in the subfamily Ruschioideae, settling quickly in deeper grounds after rain and along newly tarred roads.

This article focuses on succulent plant Nananthus Ruschioideae. The distinction of the species of Nananthus is particularly difficult in cultivated material which tends to develop longer and more slender leaves with less prominent warts than plants in habitat. Nevertheless, these latter can also vary considerably in size, depending on water regime. The six species of the plant differ mainly in leaf shapes and in some fruit characters.

This article lists the names published originally under succulent plant mesembryanthemum that cannot be included in the present circumscription of the genus.

This article presents information on succulent plant genus Lampranthus Ruschioideae. Its leaf is moderately xeromorphic and its flower is solitary or in bigger dichasia. Most species thrive in the winter rainfall areas near the Cape of Good Hope in South Africa. Although several species are used as ornamental plants in gardens, the genus has not been studied sufficiently to permit a clear delimitation of all species.

This article describes the succulent plant Hereroa ruchioideae. It is a compact to caespitose or shrubby plant. Its leaves have smooth to somewhat elevated epidermis cells and often elevations above the subhypodermal idioblasts appear as dots. Its pedicels are often longer than the leaves. Its petals are mostly golden.
