230AB46BFFB41E4FFF1723A054B7FA0C.taxon	distribution	Distribution and habitat: — Tanacetum kurdistanicum is restricted to Abidar Mountain, a subalpine region in Kurdistan. It grows on dry northern slopes between 1650 and 2000 m a. s. l. Phytogeographically, it is an Irano-Turanian element. Taxonomic notes: — Tanacetum kurdistanicum has no close relatives based on our comparisons with descriptions in Flora Iranica, Flora of Iran (in Persian), neighboring floras and recently published species accounts. Conservation status: — Based on our field observations during the last 15 years, we observed Tanacetum kurdistanicum at a few localities on Abidar Mountain. Each population counted fewer than 100 individuals. The total area of its range was about 3 km 2. Our annual monitoring revealed degradation in population size and reproduction structure. Based on the IUCN criteria and categories, we assess T. kurdistanicum to be Critically Endangered (IUCN 2022). Phenology: — Flowering April to May, fruiting July to September.	en	Rastegar, Azad, Maroofi, Hosein, Tabad, Mohammad Aref (2022): Two new species of Tanacetum (Anthemideae, Asteraceae) from western Iran.

230AB46BFFB41E4AFF17242050B5FCF2.taxon	distribution	Distribution and habitat: — Tanacetum urmiense occurs in alpine zones close to the borders of Iraq and Turkey. It grows on humid northern slopes between 2800 and 3100 m a. s. l. Phytogeographically it is an Irano-Turanian element. Taxonomic notes: — Tanacetum urmiense is closely related to T. hololeucum but differs in the following characteristics: plant height (5 – 12 cm vs. 10 – 18 cm); indumentum (glabrous or sparsely pubescent vs. densely appressed tomentose); basal leaves dimensions (35 × 12 mm vs. 15 – 80 × 10 – 25 mm); capitula diameter (10 – 20 × 20 – 30 mm vs. 8 – 10 × 6 – 7), and indumentum of the phyllaries (glabrous or sparsely pubescent vs. sparsely or densely hirsutulose). Conservation status: — Tanacetum urmiense was collected only on Dalanpar and Boz-e-Sina mountains. Fewer than 200 individuals were on each mountain. The total area of distribution was about 6 km 2. Based on the IUCN criteria and categories, we assess T. urmiense to be Critically Endangered (IUCN 2022). Phenology: — Flowering July to September, fruiting September to October.	en	Rastegar, Azad, Maroofi, Hosein, Tabad, Mohammad Aref (2022): Two new species of Tanacetum (Anthemideae, Asteraceae) from western Iran.
