Conservation status: The species is in high demand due to the presence of bioactive compounds such as Costunolide and Cynaropicrin ( Pandey et al., 2007) and is listed in Appendix I of CITES. It is overharvested for its aromatic roots and it has been reported that the natural population is decreasing rapidly ( Anonymous, 2011; Sharma et al., 2019). This species is assessed as Critically Endangered [CR A2(c,d)] in the IUCN Red List of Threatened Taxa. In our field explorations also, we came across only one population in the wild (near Lahaul-Spiti, Himachal Pradesh) but found the species in cultivation at various locations.
Notes: Victor Jacquemont made extensive collections for the Museum d’ Histoire Naturelle to the East for Voyage dans l’Inde and his specimen from Kashmir, India, is the original material for Aplotaxis lappa . In the protologue, only the collection locality is mentioned and no type was designated. A thorough search for the original material at BR, P, PC and G, where Jacquemont’s collections are reportedly located revealed one of the original material agreeing well with the protologue ( Jacquemont 727 at P [ P00602864 digital image!]) and is hence designated here as the lectotype following Art. 9.3 of the Shenzhen code (Turland et al., 2018) .

Perennial herbs, acaulescent. Leaves petiolate, oblong-obovate, 20–30 cm long, lobes pinnatifid, denticulate, adaxial surface hirsute, abaxial densely woolly. Capitula numerous, 3–15 in number, sessile to shortly peduncled, 4–5 × 2.5–3.2 cm, tomentose. Involucral bracts multiseriate, ovate to ellipticlanceolate, scabrid, scarious. Corolla tubular, linear, 2–3.5 cm long, purple. Filaments glabrous. Anther base caudate; tails lacerate. Cypsela obovate, compressed, curved, glabrous, with black wavy fringes, apex truncate. Pappus plumose, brown, deciduous as a whole.
Flowering & fruiting: Flowering and fruiting from July to October.
Habitat: Grows in alpine meadows, on rocky slopes and in rock crevices, at elevations from 3500 to 4600 m.
Distribution: India, Nepal and Pakistan.
Specimens examined: INDIA, Uttarakhand, Rudraprayag district, Tungnath , 3650 m, 03.10.2017, Shruti Kasana 1713, 1714 ( DUH) ;
Garhwal, near Chandrashila peak, 4090 m, 03.10.2017, Shruti Kasana 1735 ( DUH) .
Conservation status: During our field visits (from 2017–2020), we observed the species to be of occasional distribution but the population size has decreased over these years possibly due to over exploitation for its medicinal properties. We have also observed that its natural habitat is under threat due to increased tourist influx, leading to a decline in its extent of occurrence and the number of populations. Therefore, as the species is facing high risk of extinction from the wild, it has been assessed here as Vulnerable [Criterion B1 a,b(i,ii,iv)] following the guidelines of IUCN (2019).
Notes: Candolle described Dolomiaea macrocephala based on Wallich’s collection ( Catalogue No. 2904) from India, Gosain Than, Kumaon. However, he did not designate the type or mention the herbarium where the specimen was kept. We traced four original materials at three different herbaria: E ( E00394933 digital image!), G ( G00474692 , G00474688 digital images!) and P ( P00705232 digital image!). As the specimen at E ( E00394933 ) agrees well with the protologue, we designate it as the lectotype following Art. 9.3 of the Shenzhen code (Turland et al., 2018) .
The placement of this species in genus Dolomiaea was unclear and many authors ( Hooker, 1881; Pusalkar & Singh, 2012; Singh & Pusalkar, 2020) accepted it under the genus Jurinea . This confusion arose due to the transfer of D. macrocephala to Jurinea by Pierre Edmond Boissier in 1888. When Boisser transferred the species, the epithet ‘ macrocephala’ was preoccupied within Jurinea and hence, a replacement name was given as Jurinea dolomiaea Boiss. By applying this taxonomic change, the type of genus Dolomiaea was implicitly excluded by Boissier and hence the genus Dolomiaea was left with no type. This increased the existing confusion within Saussurea s.l. (now known as subtribe Saussureinae ). However, recent molecular work ( Herrando-Moraira et al., 2020) has clearly shown that this species lies in the Dolomiaea clade. Also, detailed morphological investigation shows that it should belong to Dolomiaea rather than Jurinea due to the absence of scales on the receptacle and yellowish pappus bristles that are not inserted on a conic cupule in Dolomiaea as compared to the presence of short scales on the receptacle and white pappus bristles that are inserted on a conic cupule in Jurinea .
