Abstract. A new species Ferula dseghica Nersesian is described from Armenia. The species has stems up to 2.5 m tall and a large rootstock. It is remarkable by not inflated, wide open leaf sheaths, by rather long peduncles of central umbels and by oblong or linear-oblong mericarps almost without lateral wings. The species occurs in Ijevan and Yerevan floristic regions of Armenia.
Keywords: Apiaceae, Ferula dseghica, Armenia, Caucasus, flora, new species.
Аннотация. Из Армении описан новый вид Ferula dseghica Nersesian. Этот вид со стеблями до 2.5 м высотой и крупным каудексом примечателен наличием невздутых, широко открытых листовых влагалищ, довольно длинных ножек центральных зонтиков, а также продолговатых или линейно-продолговатых мерикарпиев почти без боковых крыльев. Вид встречается в Иджеванском и Ереванском флористических районах Армении.

Ferula L. is one of the largest genera in the family Apiaceae Lindl., distributed in the temperate regions of Eurasia. In his superbly illustrated monograph "Generis Ferula (Tourn.) L. monographia illustrata", E. P. Ko-rovin (1947) mentioned 132 ferula species. Nowadays about 200 species are known (Pimenov, Leonov, 1993; Yaqoob, Nawchoo, 2016).
In Armenia, the genus Ferula up to now was known to be represented by 5 species growing on dry and stony slopes in lower and middle mountain belt (Mandenova, 1973). Nine ferula species have been recorded for the Caucasus as a whole (Menitsky, 2008). On the contrary, according to "Flora of Turkey" (Penmen, 1972) and "Flora Iranica" (Chamberlain, Rechinger, 1987), in these countries adjacent to Armenia, 17 and 53 species of ferula, respectively, are found. Obviously, the real number of species is much greater considering new descriptions of the last decades.
A new species was observed during last years in the Ijevan floristic region of Armenia. The species is remarkable first of all by not inflated, wide open leaf sheaths, rather long peduncles of central umbels and by almost absent lateral wings of mericarps. Two years ago another population of this species was found in Yerevan floris-tic region during the joint field trip with A. Rudov and A. Asatryan. The closest species F. coskunii H. Duman et
Sagiroglu is native to calcareous rocky places and forest clearings of S Turkey and N Israel (Duman, Sagiroglu, 2005; Danin, Fragman-Sapir, 2019). The Armenian species occurs in steppe-meadows in rocky and stony places, often at the edge of river gorges up to 1800 m a. s. l. Among accompanying species the following ones can be mentioned: Psephellus debedicus (Gabrieljan) Gabrieljan (endemic to Armenia), Melampyrum arvense L., Stachys atherocalyx K. Koch, Bifora radians M. Bieb., Peuceda-num ruthenicum M. Bieb., Physospermum cornubiense (L.) DC., Heracleum chorodanum (Hoffm.) DC., Dian-thus caucaseus Sims, Stipa pulcherrima K. Koch, Papa-ver macrostomum Boiss. et A. Huet, Dictamnus albus L., Prunus spinosa L., Rosa pimpinellifolia L.
Ferula dseghica Nersesian, sp. nova.
Perennial. Rootstock thick, 5-10 cm diam., dense fibrous collar 3-5 cm long. Stem 100-250 cm, glaucous, glabrous, 1-2 cm diam. at the base. Basal leaves ovate in outline, 25-34 x 20-25 cm; petioles 18-30 cm, glabrous; lamina 4-5-pinnate, ultimate segments linear and linear-lanceolate, 1-4.5 mm long, acute, glabrous above, sparsely pilose beneath along veins, ciliate on margins. Sheaths narrow, not inflated, membranaceous, whitish, wide open, only at the very base semiamplexicaul; lower and middle ones 6-8 x 10-15(20) mm, laminae

of lower leaves 4-5-pinnate, of middle ones 2-3-4-pin-nate (Fig. 1: B); upper leaves smaller, usually without lamina or with few segments. General inflorescence paniculate-corymbose, lax, with alternate, ascending lateral branches 10-35 cm (Fig. 1: A). Central umbels (apical umbels of each branch) fertile, long-peduncled, (1)2-4 cm, rays 10-12, 15-20 mm, mostly equal; lateral umbels (umbels of secondary branches) usually sterile, those below the central umbels single or opposite, rarely whorled (by 3); umbellules 10-20-flowered, fruiting pedicels 8-10 mm, subequal. Bracts and bracteoles absent. Sepals persistent, reflexed, 0.1-0.4 mm long. Petals yellow, long attenuate, 0.5-0.8 x 1-1.5 mm, inflexed. Anthers yellow (Fig. 1: C). Mericarps oblong or linear-oblong, 7-8 x 3-3.5 mm, brown when ripe (Fig. 1: D); dorsal ridges filiform, lateral wings almost absent, up to 0.25 mm wide. Stylopodium conical. Styles persistent, strongly reflexed, appressed to the mericarps, stigma capitate; dorsal vittae solitary per vallecula, commis-sural vittae always 2 (Fig. 2). Fl. June, Fr. July-Aug.
