REMARK

C. meyeri is reported from north Iran in Mazandaran province ( Fig. 7A ). The species belongs to subgenus Chaenopetalum ( Fryer & Hylmö 2009). This species is related to C. multiflorus Bunge ( Browicz 1972) , from which it differs for its black-purple fruits (vs light red to red), acute to obtuse (vs obtuse to rounded) and shorter leaves (15- 39 mm vs 20-55 mm), fewer- flowered inflorescence (5-8 vs 5-13) and indumentum of pedicel in fruit (glabrous vs thinly tomentose) ( Fig. 7B ). The geographical distribution of the species is Afghanistan, Tajikistan, Kyrgyzstan, Azerbaijan ( Riedl 1969; Pojarkova 1971; Fryer & Hylmö 2009) and Iran.

NOTE

C. meyeri was not previously reported from the flora of Iran ( Riedl 1969). Later, this species was reported there without locality information ( Fryer & Hylmö 2009). In the framework of this paper, this species was collected again, and it is reported for Flora of Iran.
