Western Himaiata; from Kashmir to Kumaon, alt. 7-9000 ft. ■Westehnt 

 Tibet; in salt plains, alt. 9-14,000 ft., abundant. — Disteib. Coasts of Europe and 

 saline tracts of N. Asia. 



Bootstock woody, branched; stems 6-18 in., strict, woody or wiry.' Leaves ^2in.,. 

 often quite ■white, with very many segments ; petiole slender. Heads often reddish, 

 crowded and braeteolate by a small linear or almost setaceous leaf. — The heads are 

 erect in most of the Indian specimens, ■which refers them to the form called fragrans 

 of Willdenow, but Clarke mentions a variety with nodding heads which he (in mss.) 

 refers to A. nutans, Willd. ; and he has a var. Thomsoniana for a form with very 

 woolly leaves and suberect heads {A. Lehmaniana, Bge.). Wallich's A. brevifolia in 

 no way differs from A. maritima. 



Sect. III. Abrotanum. Heads heterogamous ; ray-fl. ? , disk-fl. (^ , all 

 fertile ; receptacle naked (or puberulous in A. persica).

 Armenia. 



Very stout, 2-4 ft ; stem green or purplish. Leaves green, 3-5 in. long, soft, 

 petiole and rachis slender. Heads clustered like the inflorescence of an Amaranthm. 

 Achenes larger than usual in the genus, about i in. long. — The Sikkim plant referred 

 to this by Clarke (1. c.) is A. biennis, which differs 'widely in the size, form and colour 

 of the heads, and in the broad receptacle.
