Abstract

Specimens belonging to the genus Daphne L. (Thymelaeaceae) were collected from the northern parts of Iran, which had the following morphological characteristics: Plant shrubby, to 1 m high, stems firm, older brown, younger green,bark brown,leaves crowded at the end of branches, apparently not leathery in dry state, lower leaves deciduous, leathery, obovate-lanceolate or oblong-elliptical, acute, narrowed at base, glabrous, 3-10 × 1. 5-3. 5 cm,inflorescence axillary, 2-flowered,peduncles axillary, 10-25 mm long,pedicles 2-3 mm long,flowers yellowish green,hypanthium narrow, lanceolate, unequal, two lobes shorter than others,ovary glabrous,drupe red, 5-6 mm long, 3-4 mm broad (Fig. 1). Taking into account of the above-mentioned characteristics as well as the available references (Boissier et al. 1879, Pobedimova 1949, Parsa 1951, Peterson 1972, Tan 1982, Edmondson et al 1982, Akhiani 1995), the specimen was identified as Daphne pontica subsp. haematocarpa G. Woronow and is reported for the first time for the flora of Iran. This subspecies is distributed from Eastern Europe to Caucasia and grows in the woods or shrubby slopes, an evergreen, with many flowers and fruits, and has a strong scent, especially in the evenings. In the existing classifications, the species Daphne albowiana is made a synonym of this subspecies (Takhtajan 2012). The subsp. haematocarpa differs from the subsp. pontica in the color of the ripe fruits. In the subsp. haematocarpa, the fruits are bright red to maroon (Cullen et. al. 2011, Pobedimova 1949, seidelbast. net), while the fruits of the subsp. pontica are black (Cullen et. al. 2011, Pobedimova 1949). The flora of the USSR considers the non-leathery leaves as another distinctive characteristic. However, it seems that, this opinion is made without the observation of the fresh plant, because in both taxa the fresh leaves are leathery, while the younger ones appear non-leathery in dried herbarium specimen, thus in the present key, it is not considered as a distinctive characteristic. It is interesting to note that, according to Pobedimova (l. c. ), the type specimen of the taxon has been lost! Based on the above-mentioned points, the following key is presented to distinguish the subsp. haematocarpa from its close taxon in Iran: 1. Ripe fruit in nature, red. . . . . . . . . . . . D. pontica subsp. haematocarpa -Ripe fruit in nature, black. . . . . . . . . . . . D. pontica subsp. pontica Material examined: Iran: Gilan province, Rostam-Abad, forest beside Vistan lake (under the canopy of Fagus orientalis trees), 36˚, 45' N, 49˚, 45' E, 15. 8. 2019, Eskandari & Mostofi (IRAN 77888).
