I have named this plant in honour of George Earl Auckland, Governor- 

 General of India, not in compliment to his rank, hut as ;i distinction well 

 merited by his Lordship's services in the cause of Indian botany. The plant 

 was met with during a journey in Cashmeer, undertaken under Lord Auck- 

 land's auspices ; and its value, as yielding a useful product, makes the appli- 

 cation appropriate to the useful direction of his Lordship's views in promoting 

 botanical investigation in our Indian empire. 



Aucklandia partakes of the characters of Saussurea, Dolomicea and Carlhia. 

 Its technical difference from the first mainly rests on the characters of the 

 pappus, which, however, in conjunction with the habit, are sufficiently marked 

 to entitle the plant to the rank of a distinct genus. 



De Candolle founds his distinction between Saussurea and Aplotaxu upon 

 the single row of setae in the pappus of the latter. But this ground is tin- 

 tenable, as a considerable number at least of the Himalayan species have 

 really an outer row of very caducous and filiform setae, while the inner row is 

 more permanent. These outer setae frequently disappear in the dried spe- 

 cimen, or are detected with difficulty. Probably De Candolle has drawn his 

 inference from specimens imperfect in this respect. The fact was observed 

 and first brought to my notice by my friend Mr. M. P. Edgeworth. Lagu- 

 rostemon, which De Candolle comprises as a section of Saussurea, seems to 

 have better claims to the rank of a distinct genus than Jp/ota.iis.
