Distribution : Southern Europe, Turkey (Anatolia), Iran, Near East, also recently cited from Spain and Serbia; usually very local.

 

 

Description (by 't Hart & Bleij in IHSP 2003) :

 

Short-lived small glabrous annual herbs with erect or ascending usually simple branches to 6 cm tall.

 

Leaves alternate, imbricate and erect-appressed, sessile with a scarious basal spur, conical-oblong, 3 - 5 mm, subacute, terete or semiterete, often with ciliate or denticulate margins, glaucous or dark green.

 

Inflorescences cymose, usually consisting of 1 cincinnus (large specimens often with 2 or more cincinni), bracts 2, leaf-like, large.

 

FIowers 4- (or 5-) merous, autogamous, sessile, with 4 or 5 stamens, sepals basally free and spurred, strongly unequal, to 4 mm, acute, semiterete, often with ciliate margins, petals free, oblong, 2 - 3 mm, subacute, white, sometimes tinged red, filaments white, anthers small, yellowish or red.

 

Cytology : 2n = 26, 52.

 

Belonging to the monotypic Ser. Macrosepala (Regel & Schmalhausen) Borissova. It was recently also cited from several provinces of Spain (Ríos Ruiz & Al. 1993: 166) and for Serbia (Zlatkovic & Randjelovic 1996).

 

Sedum aetnense in Greece near Florina, no one had reported this little oddity from this country. Full-grown plants were 10mm high.

S. tetramerum - now synonymous with S. aetnense :

Near Iraqi border S of Lake Van c2000m. Sedum tetramerum can be separated from S. aetnense by only one feature (non-entire sepals) so perhaps it is best to unite.
