Habitat and Ecology: This species grows without shelter in compact clumps in grassland with open patches of thicket in cracks and hollows of shallow pans on sandstone plates together with Aptenia cordifoliaSN|28876]]SN|28876]]. Rainfall: about 380 mm per annum. It is not treatened. The current owner on the farm on which they grow is aware of them and their importance, and is endeavouring to protect them.

ENGLISH: Dwarf tiger jaw
Description: Faucaria gratiaeSN|17876]]SN|31997]] (Faucaria hooleaeSN|16572]]SN|31998]]), also known as the "dwarf tiger jaw", is one of the smallest member of this genus. It grows in small compact clusters with leaves more or less erect, spreading only when pressed by a subsequent leaf. Leaves are short shiny greyish green, often red-tinged, with many small dots. In habitat it resembles Faucaria tigrinaSN|14721]]SN|14721]] but is different from this species in its smaller seeds and fruits as well as having fewer teeth (only 2 to 5 teeth on each margin ) which are restricted to the upper half of the leaf.
Note: Faucaria gratiaeSN|31997]]SN|31997]] and Faucaria hooleaeSN|31997]]SN|31998]] are known only from three herbarium sheets. The descriptions do not differ significantly and the type specimens originate from the same population. Up to date Faucaria hooleaeSN|31998]]SN|31998]] has been reduced to being the same as Faucaria gratiaeSN|31998]]SN|31997]].
Leaves: Ovate to elliptic-ovate 20-25 mm 1ong,10-20 broad, more or less erected, surfaces dark shining green or olive green, something purple at the base, otherwise reddened. All leaf faces with crowded, white, small, raised dots, the keel is white, margins are white throughout or with white bases to the 2-5 teeth, these conical and without or with awns up to 4 mm long, to purplish.
Flowers: Yellow. Sepals 5, 8-10 mm long, base 2.5-5.0 mm broad, unequal, Petals between 60 and 85 linear, emarginate to acuminate,15-21 mm long, 1-1.75 mm broad. Stamens 110-140 8-9 mm long; filaments white. Nectar glands dark brown to orange. Stigmas 8-11 mm long, shorter than longest stamens.
Fruits (capsule): Sessile or with a short fruit stalk up to 1 x 3 mm wide, 1 mm thick. Base of fruit bell-shaped, top rather low, 7-9 mm long, 6-9 mm in diameter.
Seeds: 1.2-1.3 mm long, 0.85-1 mm broad.
Phenology: Flowering period: March—May.
Similar species: Faucaria gratiaeSN|31997]]SN|31997]] resembles Faucaria tigrinaSN|14721]]SN|14721]] when found in habitat because both species keep the leaves of a pair rather closed and erect. F. gratiae are very small with short leaves and irregular margins, rather different from those of Faucaria felinaSN|31998]]SN|16572]]. It also has fewer teeth restricted to the upper half of the leaf, and lacks confluent flecks, the seeds and fruits are smaller too. In the white keel and margins, F. gratiae resembles Faucaria bosscheanaSN|31997]]SN|17876]].
