description: Gypsophila alvandica Falat., F. Ghahrem. & Assadi, sp. nov. (Figs. 1−2).   
 Type:— IRAN. Hamedan Province. Hamedan: Near Ganjname, 2100 m, 8 July 1981, Assadi & Mozaffarian 36774 (holotype TARI!).   
 Diagnosis:—Perennial herb. ± glandular-hairy especially above all nodes (not only above upper nodes). Stems few (not several), up to 5 mm in diameter, Leaves linear-lanceolate to lanceolate, acute or apiculate. Petals oblong with a shallow contraction in the middle, truncate to retuse (not cunneate), pink with purple veins (not cream or pale yellow). Ovules 8–16, Seeds orbicular-reniform, compressed, with flat tipped tubercles, about 1.0–1.3 × 1.0– 1.4 mm (not with obtuse tubercles about 1.5 × 2. mm).   
 Description:—Perennial. Stems few, up to 5 mm in diameter, branching throughout, erect, yellowish green, ± glandular-hairy especially above the nodes; Internodes 2.0– 8.5 cm long. Lower leaves 10–50 × 3–13mm, lanceolate to narrow lanceolate, narrowed at the base; upper leaves 7–20 × 1–7 mm, linear-lanceolate to lanceolate, acute or apiculate. Inflorescence lax, compound dichasial. Bracts 1–2 mm long, lanceolate, acuminate to caudate, scarious with a purple midrib. Axial pedicels 10–30 mm long; lateral pedicels 5–10 mm long. Calyx campanulate, 5-ribbed, 2.5–3.0 mm long, incised nearly to the middle; lobes ovate to ovate-lanceolate, acute to apiculate sometimes obtuse, green bands twice as broad as the scarious intervals sometimes with a purple shade, with crowded crystals especially in the scarious intervals. Petals 4.0– 5.5 mm long, oblong with a shallow contraction in the middle, truncate to sub retuse, pink with purple veins. Stamens 10, shorter to equal the petals. Ovary globose, with two styles with terminal stigmatic surface. Ovules 8–16. Capsule unilocular, globose, about 3 mm long, splitting into 4 valves. Seeds orbicular-reniform, compressed, with marginal hilum, about 1.0–1.3 × 1.0– 1.4 mm, with glossy surface. In terms of exomorphology, the surface of the seed is constructed of regularly polygonal to elangate cells with irregular dentate margins and convex periclinal walls.   
 Phenology: —Flowering and fruiting: May to July.   
 Etymology: —The specific epithet refers to Alvand Mountain in Hamedan province where the type specimen was found.   
 Taxonomical notes: — Gypsophila alvandica belongs to sect. Dichoglottis (Fischer & C.A.Mey (1835: 25) Boissier (1867: 536) by its lax inflorescence and long filiform pedicles. This species differs from G. polyclada Fenzl ex Boissier s.lat. [1867: 542; the lectotype (at W! image is availale at http://herbarium.univie.ac.at/database/detail. php?ID=403609) was designated by Barkoudah (1962: 144)] in having a lower number of stems, glandular-hairy lower internods, pink and oblong petals, 8–16 ovules and smaller seeds which have coated by polygonal testa cells with irregular dentate margins and convex periclinal walls (Table 1). In both variety of G. polyclada [var. polyclada and var. glandulosa Barkoudah (1962: 144)] the seed surface is characterized in having regularly arranged elongate cells with sinuate margins and convex periclinal walls. The periclinal wall in both varieties shows many cylindrical protuberances and granules (Fig. 4A–I).   
  Pollen morphology: G. alvandica : Monade, apolar, rounded polyhedral, 25−27 μm Aperture pantoporate. Pores 2.00−2.25 μm in diameter, annulate. Distance between pores (without annulus) 2.5−4.0 μm. Annulus with granules, operculate. Ornamentation is nanoechinate-nanoperforate (Fig. 4J, M).   
  G. polyclada var. polyclada : Monade, apolar, spheroidal, 25−27 μm. Aperture pantoporate. Pores 2.3−2.7 μm. in diameter, annulate. Distance between pores (without annulus) 5−6 μm. Annulus with granules, operculate. Ornamentation is nanoechinate-nanoperforate (Fig. 4K, N).   
  G. polyclada var. glandulosa : Monade, apolar, spheroidal, 23−25 μm. Aperture pantoporate. Pores 2.8−3.0 μm. in diameter, annulate. Distance between pores (without annulus) 3.5−5.0 μm. Annulus with granules, operculate. Ornamentation is nanoechinate-nanoperforate (Fig. 4L, O).   
 Distribution and habitat: —The new species is endemic to west and central Iran (Fig. 3) where grows on volcanic rocky slopes or sandy stony mountain, at 1980−2700 m a.s.l.
