Description: Aeonium spathulatumSN|34872]]SN|34872]] is a perennial succulent shrublet between 20 and 65 cm tall (depending on the form). It is very bushy, has slender branches and small spoon-shaped sticky leaves. The flowers with 8 to 10 petals are golden yellow. Aeonium spathulatumSN|34872]]SN|34872]] belongs to the group of small shrubby species, with branched stems and short leaves. It differs from other species because the leaves, obovate-spatulate and small, have linear glands on the underside and ciliated margin, the branches being smooth, not reticulated. There are two varieties: var. spathulatum and var. cruentum (Webb & Berthel.) Praeger, the latter only in the islands of El Hierro and La Palma.
Derivation of specific name: spathulatum, for the leaves that are spatulate (with a broader, flattened end).
Stem: Densely branched, branches, woody 1-3 cm in diameter, puberulent, smooth, without reticulations.
Rosettes: 1-5 cm cm in diameter, more or less flat to distinctly cup-shaped, inner leaves more or less erect. In summer the leaf rosettes will close completely, and they will open again at lower temperatures in autumn.
Leaves: 5-25(-30) mm long, 3-9 mm wide, 1-1.5 mm thick, obovate-spatulate, apically obtuse, basally cuneate or attenuate, puberulent (finely hairy) and a bit sticky; lower face at first green, later brown, with conspicuous longitudinal brownish tannic stripes and sunken oblong glands. Margin with translucent bead-shaped cilia (0.7 -1 mm long). In summer, the leaves are often dropped, except for the youngest.
Inflorescence: Floriferous part lax, 3-10 cm long, 3-15 cm broad; peduncle 5-20 cm tall; Pedicels 1-10 mm long, puberulent
Flowers: 8- to 10-merous; Sep puberulent; Petals 4.5-6 mm long, 1.5-2 mm wide, elliptic, obtuse, yellow, often with reddish lines; Filaments glabrous.
Chromosome number: 2n = 36.
Notes: Aeonium spathulatumSN|34872]]SN|34872]] is quite variable, the El Hierro form is smaller than the typical form from Tenerife. The La Gomera form is much taller and more upright growing with slightly smaller and sticky, fresh green leaves with an acute tip on greyish brown stems. The form from Gran Canaria is more compact with slightly larger, strongly sticky leaves with a triangular like, broad flattened tip, and it is native of central parts of Gran Canaria.
