국표에 없다.

Origin and Habitat: Conophytum maughaniiSN|22606]]SN|22606]] subsp. latum is endemic to the Namaqualand, Northern Cape (South-eastern Richtersveld between Eksteenfontein and Umdaus), in the Republic of South Africa (Extent of occurrence 681 km²). It is widespread with scattered individuals, and sometimes locally common.
Habitat and Ecology: This species grows on quartz flats in the Succulent Karoo in various types of succulent shrubland. There are no severe threats to the taxon, although some small subpopulations may be damaged by road tracks and localised mineral exploration diggings. It is however unlikely to be causing a significant overall decline to the population.

Description: Conophytum maughaniiSN|22606]]SN|22606]] subs. latum, is a distinctive subspecies of Conophytum maughaniiSN|22606]]SN|22606]] with convex, windowed bodies. Its bodies occur singly or in pairs and are cylindrical to conical, up to 25 mm tall, yellowish-green to brilliant red, and slightly papillous, and the flowers are smaller, nocturnal and very strongly scented.
Derivation of specific name: This subspecies has been named for its proportions; the bodies are often broader than tall. Dried sheath pale brownish-yellow, marked with scattered tannins (dots), very thin.
Body (paired leaves): Single, in pairs or very sparsely branched, sunken, 8-15(-20) mm long, 15-20(-25) mm wide, 10-15(-20) mm thick, depressed- globose to turbiniform (conical) with a small central depression. The apex is often smaller than the base. The end surfaces of the lobes are somewhat truncate to slightly convex, translucent (windowed) or nearly opaque. The epidermis is glabrous, pale yellowish-green to beet-red or ochre, marked with greenish idioblasts (water storage cells and tannin cells), often opalescent near the fissure. The fissure is short, sunken, glabrous.
Flowers: Small, nocturnal, milk-white to pale yellowish or peach-pink very strongly scented. Bracts short, hidden in the body. Calyx- short, green or pinkish-green, with 5-7 greenish sepals 2-3 mm long. Petals ca. 50-70 in 3-5 series white to yellow or pink, usually short (ca. 10 x 2mm), spathulate, innermost ones very thin. Stamens many, reaching or exceeding the mouth of the tube, anthers pale yellow; stigmas 5-7, free.
Fruit (capsule): 7-locular, 2 mm long, 5 mm wide, quite soft, depressed obovate, pale brown, sparsely dotted.
Seeds: 0.45 long, 0.35 wide, 0.30 mm thick, densely papillate.
