Gilan, Asalem to Khalkhal (Asbdavani), 1876 m, 37°37’4.68”N, 48°46’2”E, 12.VIII.2004, Moazzeni & Keshvari 34941 (holo-, TUH!; iso-, P [ P04022112 ]) .

HABITAT AND ECOLOGY. — Verbascum parsana sp. nov. is known only from the type specimen and one locality (type location) in north of Iran ( Fig. 2 ). Based on present study it is a narrow endemic taxon. The new species grows on porous and soft sandy-clay soils at elevation of 1876 m in transition zone out of forest .

ETYMOLOGY. — The epithet is to honor Dr Ahmad Parsa (1907- 1997), the first Iranian botanist who produced important concepts for flora of Iran.

inflorescence region. Stem up to 60 cm long, terete. Basal leaves oblong-elliptic, semi-crenate at margin, with up to 5 cm long petiole, tapering toward apex, 5-8 × 2-3 cm; cauline leaves are similar to basal ones but smaller, not decurrent. Inflorescence paniculiform, lax; flowers single at the axil of each bract; bracts linear-acuminate; bracteoles absent; pedicel up to 8 mm long ( Fig. 1B, C ), covered with stellate and glandular hairs; calyx 4-6 mm long, divided, with elliptic segments ( Fig. 1B, C ); corolla yellow, 15 mm in diam ( Fig. 1D ), densely stellate and glandular hairy outside; stamens 5; hairs of filaments violet; 2 anterior stamens naked from the top to ¾ (blue arrows Fig. 1E ), only the last quarter of the filaments close to the corolla hairy ( Fig. 1E ); anthers reniform, 4-5 mm long; stigma 4-5 mm ( Fig. 1D ). Capsule elliptic-obtuse, 5-7 mm long, covered with dense stellate and glandular hairs ( Fig. 1C ).

DISCUSSION AND CONCLUSION

The new species described as V. parsana sp. nov. has a combination of characters that is uncommon within the genus Verbascum . Only a few species have both stellate and glandular hairs together such as V. punalense and V. sinuatum L. var. adenosepalum Murb .. If we consider the combination of characteristics: ebracteolate and single flowers, violet hairs on filaments, pedicel size between 3 to 10 mm and stellateglandular indumentum, the new species is closely related to V. punalense but cannot be mistaken with it because it has no decurrent anthers, the basal leaves are narrow, the corolla is smaller, its calyx lobes are acute and have sparse glandular-stellate hairs ( Table 1 ).

Based on Murbeck (1933), the new species belongs to the subsection II, Singuliflora, and to the group ebracteolata. Seven species have been described in this section. But they all differ from V. parsana sp. nov.

There is no species looking like this new species in any of the recent floras published since then ( Ferguson 1972; Feinbrun-Dothan 1978; Huber-Morath 1978; Huber- Morath 1981; Fedtschenko 1997; Ibn Tattou 2007; Benedi 2009; Sharifnia 2011).

The phylogenetic dendrograms constructed using distance method on molecular data and on morphological data, confirm the difference of our new species with V. punalense and V. shahsavarensis on both analyses ( Fig. 3 ).
