Description: Faucaria specieosa (Syn: Faucaria felinaSN|16572]]SN|16572]] subs. britteniae) is a local or morphological form of the very variable Faucaria felinaSN|16572]]SN|16572]] with curious toothed leaves fitting together rather like the jaws of an animal. It is not easily separable by any significant character from the standard Faucaria felina, if not for a more glaucous colour, and a rough surface and for the geographical provenance.
Habit: It is a compact, little branched, perennial succulents forming compact, slow-growing, almost spherical mounds.
Stem Very reduced, tufted and developing a very short branched rhizomatous trunk with age.
Rosettes: Clumping, 4-6 leafed, each up to 12 cm in diameter.
Leaves: Up to 70 mm long, 5-20 mm broad, slender, spreading, rhomboidal, somewhat elongated, riangular in cross-section,tapering gradually, keel sharp, white forming a pronunced chin. Margins with 5-8 teeth in the upper half (rarely more or less); teeth broad, fleshy, curved, white or pink ending in papillate awns of 0,5 to 3 mm length. Faces of leaves glaucous grey-green, rough, wax cover thin, crystals in the outer walls in certain areas resulting in white dots.
Flowers: Daisy-like 3,5 cm in diameter with yellow petals.
Blooming season: Late autumn to winter.
Fruit: Base broadly bell-shaped, top with the valves often raised in the centre, 10-16 mm long, 9-11 mm in dameter.
Seeds: 1,4-1,5 mm broad.
Subspecies, varieties, forms and cultivars of plants belonging to the Faucaria felina group
- Faucaria candida L. Bolus: has large white flowers and leaves more or less uniform bright green without tubercles or pale speckling. Distribution: Cradock, Eastern Cape Province, South Africa.
- Faucaria cradockensis L. Bolus: ((syn: Faucaria felina subs. felina) has long unspotted leaves with white or pink teeth. Distribution: Hill above Cradock, Somerset East Dist., Eastern Cape.
- Faucaria felina Schwantes: has slender, spreading leaves with an oblique tip of the leaf. The lower number of teeth and the less spots separates it from Faucaria tigrina, which also has more erect leaves. Distribution: Eastern Cape-Province.
- Faucaria felina subs. britteniae (L. Bolus) L.E.Groen: has stouter whitish-grey green leaves, with darker-grey tiny dots, amd the keel meeting the upper leaf surface nearly at a right angle at the apex. Distribution: Albany, Grahamstown and Fort Beaufort, Eastern Cape.
- Faucaria felina subs. tuberculosa (Rolfe) L.E.Groen: Plant with large white tubercles or warts on upper leaf surface and soft white teeth along the edges. Cultivated plants shows a wide morphologic variability. Distribution: Bedford, Cape Province.
- Faucaria felina subs. tuberculosa cv. Super Warty: has large bumped and tangled tubercles or warts on upper leaf surface and soft white teeth along the edges. Origin: supposed from Japan.
- Faucaria longifolia L. Bolus: has long slender, more green leaves, keeled towards apex and with more numerous teeth. Distribution: Cape province.
- Faucaria lupina (Haw.) Schwantes: has silvery green, long, triangular leaves, with fierce-looking teeth along the upper margin. Distribution: Uitenhage, Eastern Cape Province.
- Faucaria speciosa L. Bolus: (syn: Faucaria felina subs. britteniae) has a more glaucous colour, and a rough leaf-surface. Distribution: Albany, Eastern Cape Province.

Faucaria speciosa Photo by: Cactus Art Faucaria speciosa Photo by: Cactus Art Cultivation and Propagation: Faucarias are the good choice for anyone wanting to start growing succulents. They are quite hardy and can take a short period of light frost and in very dry warm regions these succulents make very impressive out door ground covers. They need full sun to light shade with a well-drained soil mix, but can tolerate a wide variety of soil types and growing locations as long as there is plenty of sun. The plants are well watered during the growing season and allowed to dry thoroughly before watering again and will tolerate some over watering, but the challenge is to help them keep their compact form and prevent elongation of the stem. During the winter months, the plants should be kept very dry, only watering enough to keep the leaves from shrivelling.
As house plants they tend to grow in fair weather and rest when temperatures are too hot or too cool.
Propagation: Faucaria is very easy to start from seed. Seeds germinate in 7-14 days at 21°C. Although they will start from cuttings, it is quite difficult to get them to root. If they start to rot there is usually part of the plant that can be removed and possibly rooted.
