Ramaliella Zaika, Sukhor. & N.Kilian   gen. nov.

= Scorzonera subsect. Intricatae   Boiss., Fl. Orient. 3: 756. 1875.

Scorzonera sect. Intricatae   (Boiss.) Lipsch., Fragm. Monogr. Gen. Scorzonera   1: 10. 1935. Type (Art. 10.8, see Turland et al. 2018): Scorzonera intricata   Boiss.

Type species.

Ramaliella polyclada   (Rech.f. & Köie) Zaika, Sukhor. & N.Kilian

Note.

The new genus corresponds to the Scorzonera polyclada   clade. Morphologically, Ramaliella   resembles Lipschitzia divaricata   , but differs by the caudex surface, size of the capitula and the achene anatomy of a type of its own.

Diagnostic features.

Subshrubs or perennial herbs; stems numerous, intricately and divaricately branched (Fig. 16A View Figure 16 ); leaves few, the lower leaves filiform, the upper leaves reduced, curved; pollen with 24 lacunae; capitula terminal, with 3-12 florets.

Description.

Habit, life form, subterranean parts: subshrubs or perennial herbs with taproot, often with cushion-like habit.

Leaves: few, the lower leaves filiform, the upper ones reduced, curved, entire or denticulate.

Synflorescence: stems numerous, strongly divaricately and intricately branched, glabrous or puberulent, capitula terminal.

Capitula: involucre glabrous or pubescent, phyllaries in several series, the outer phyllaries tiny, triangular, the inner phyllaries linear-lanceolate much longer than the outer ones, receptacle naked, flat, florets 3-12, yellow, slightly exceeding the involucre (Fig. 16B View Figure 16 ).

Pollen: echinolophate, tricolporate and each colpus divided into 2 lacunae, with 24 (6 abporal, 6 equatorial, 6 interporal, 6 polar) lacunae ( R. tortuosissima   : Askerova 1987).

Achenes: 7-12 mm, cylindrical, without carpopodium, with five main ribs and five (or even more) barely noticeable secondary ribs, surface smooth; achene wall with parenchyma of both thin- and thick-walled cells, sclerenchyma forming a sheath (sometimes irregularly discontinuous), with an invagination on either side of the principal rib, cells orientated parallel to the achene axis, air cavities absent, tannins absent or rarely present in cell wall only ( R. koelpinioides   ).

Pappus: 11-18 mm, fulvous or dirty white, bristles plumose, but in upper part scabrid.

Chromosome number.

x = 7, diploid (data for R. koelpinioides   and R. tortuosissima   : Razaq et al. 1994).

Etymology.

The new genus is named after the specific “brushwood” habit ( rāmālia: brushwood).
