Lamiaceae

S. lavandulifolia Vahl, Symb. Bot. 1:42 (1790).
Suffrutescent perennial with basal rosettes of sterile shoots. Flowering stems numerous, 10-30 cm, sparsely to densely pilose, sometimes absent, rarely white-tomentose with unequal stellate hairs. Basal leaves subsessile to sessile, oblong-lanceolate to oblanceolate, 2-6 x 0.4-1.5 cm, entire to faintiy serrate, attenuate at base, cauline similar. Floral leaves oblong to ovate, 1.2-2 x 0.25-0.8 cm, shorter than verticillasters. Verticillasters (at least lower ones) usually remote, (2-)4-6-flowered. Bracteoles few, linear, 2-3 mm, hirsute. Pedicels 1.5-2 mm. Calyx ± regular, subcampanulate, patently pilose, tip softly spines-cent. Corolla purple to mauve, 13-15 mm, tube subincluded. Nutlets obovoid, 2.5-3 x 2-2.5 mm. Fl. 5-8. Limestone to igneous rocky slopes and screes, 1000-3660 m.
1. Calyx teeth 1-1.2 x as long as tube; leaves shortly whitish-tomentose, cauline oblanceolate with ± obtuse apex var. brachyodon
1. Calyx teeth 2-3.8 x as long as tube; leaves sericeous-tomentose or glabrous, cauline lanceolate with acute apex
2. Leaves and stems ± glabrescent with few subsessile to sessile glands var. glabrescens
2. Leaves and stems sericeous-tomentose with glandular hairs var. lavandulifolia

N. Iraq, N.W. Iran (Azerbaijan). Ir.-Tur. element. Var. lavandulifolia is very variable in indumentum density, height of flowering stems, density of inflorescence and calyx teeth/tube ratio. The range of population variability occurring in N.E. Anatolia differs from that in S. & Inner Anatolia; the former is more elongate and sparsely hairy than the latter, whereas the calyx teeth/ tube ratio varies equally in both. As the characters may well be influenced by habitat differences, the two groups are not given formal taxonomic recognition here.
Sect. Olisia Dumort. Suffruticose to fruticose perennials, rarely biennials to annuals, with or without basal rosettes, xerophytic. Flowering stems branched, adpressed tomentose to pubescent. Leaves ovate-elliptic to oblanceolate or orbicular. Bracteoles few, setaceous or rarely herbaceous. Calyx sub-bilabiate, narrowly campanulate; teeth subequal with aristate tip. Corolla tube sub-exserted, annulate (except S. inanis). Nutlets obovoid, slightly winged at base.
Subsect. Rectae Bhattacharjee. Suffrutescent perennials without basal rosettes. Indumentum antrorsely pubescent, rarely floccose-tomentose. Lower cauline leaves with cuneate to attenuate base. Bracteoles few, inconspicuous, linear to setaceous.
