Orobanche arpica Piwow., Ó. Sánchez & Moreno Mor. (2018c: 66) . Type :— ARMENIA ( holotype ): Shirak prov. : Javakheti range, E of villages Ghazanchi – Ashotsk , 22 July 2017 , R . Piwowarczyk ( KTC !); isotypes : ( ERCB !). Fig. 45F . FIGURE 63. Distribution of Orobanche arpica in Armenia. Distribution: —The species is known only from the type locality in northwestern Armenia in Shirak province ( Fig. 63 ). Habitat: —Grows in a subalpine meadow, on the SWW slope of Mt Ampasar, with NW exposure, 2225–2230 m . Hosts: —Parasitic on Psephellus pulcherrimus (Willd.) Wagenitz [ Aetheopappus pulcherrimus (Willd.) Cass. ] ( Asteraceae ). Phenology: —Flowering in the first half of July, fruiting in the end of July to early August. Conservation status: —Critically Endangered (CR) – B 1 ab (iii) + 2 ab (iii); D. So far, known only from one locality from Armenia . The population is small, ca. 30 individuals. Limiting factors are restricted EOO and AOO. Notes: — Orobanche arpica clearly belongs morphologically and phylogenetically to species from the O. ser. Krylowianae Piwow., Ó. Sánchez & Moreno Mor., O. subsect. Curvatae (Beck) Piwow., Ó. Sánchez & Moreno Mor. (see also key, and comparative table with related species and discussion in Piwowarczyk et al . 2018c ). Specimens examined: — ARMENIA . Shirak prov. : Javakheti range, E of villages Ghazanchi –Ashotsk , subalpine meadow, NW exposure, 2225 m , 22 July 2017 , R . Piwowarczyk ( ERCB , KTC ) .
