Note: This section was described, based on the entirely scabrid pappus, a remarkable feature in Gelasia   and the subtribe. Three species were reported to form this section: S. dependens   Rech.f. (= S. cretica   Willd.), S. araneosa   Sm. and S. eximia   Rech.f. The first species (as S. cretica   ) was nested in our nrITS phylogeny in the Gelasia   clade. Two species, S. cretica   and S. araneosa   , were included in our carpological analysis and match the carpology of Gelasia   .

Diagnostic features.

Perennials; leaves entire; involucre often pubescent; achenes often densely lanate, rarely glabrous, usually smooth rarely with emergence; pappus often rigid, plumose in lower portion and scabrid in upper portion or rarely almost completely scabrid; sclerenchyma forming a sheath, with an invagination on either side of the principal rib.

Description.

Habit, life form, subterranean parts: perennial herbs of various habits, rarely subshrubs (only G. acantholimon   ), with a taproot, more rarely with globose or cylindrical tuber.

Leaves: rosulate or cauline, sessile or petiolate, linear to ovate, often hairy (frequently very densely so, fleecy, lanate) or glabrous, margin entire and flat or undulate.

Stem, synflorescence: scape-like, small or leafy, tall and branched, often pubescent, more rarely glabrous (usually like those of the leaves), synflorescence racemiform, spiciform or corymbiform or capitula single.

Capitula: involucre usually pubescent, sometimes glabrescent at fruiting or rarely glabrous, phyllaries in several series, all lanceolate or triangular, outer phyllaries < 3-4 times smaller than the inner ones, receptacle glabrous or hairy, capitula of many yellow florets (Fig. 15C View Figure 15 ) or, rarely, only 4-6 ( G. acantholimon   ), well exceeding the involucre.

Pollen: echinolophate, tricolporate and each colpus divided into 2 lacunae; with 18 (6 abporal, 6 equatorial and 6 interporal) or, more rarely, 24 (in addition with 6 polar: G. lanata   , G. pygmaea   ) lacunae ( Blackmore 1982; Pinar et al. 2016), extensive echinate polar areas present.

Achenes: 4-12 mm long, without carpopodium, often densely covered with long woolly indumentum, more rarely glabrous, straight or slightly curved, 5-ribbed or roundish, smooth or rarely with stout conglomerations ( G. caespitosa   , G. pygmaea   and G. villosa   ), parenchyma usually insular above invaginations of the sclerenchyma and below the principal ribs or only insular above invaginations of sclerenchyma, air cavities absent, sclerenchymatous layers continuous or discontinuous in the main ribs, forming a sheath, with an invagination on either side of the principal rib, fibres orientated parallel to the fruit axis, tannins absent.

Pappus: 5-24 mm; bristles plumose in lower portion and scabrid in upper portion or more rarely, almost completely scabrid; dirty white, yellow or fulvous.

Chromosome number.

x = 6 (rarely 7), diploids or tetraploid.
