It is difficult to find something to say that is specially 

 applicable to a given species in a genus numbering upwards 

 of a thousand species, but Senecio tanguticus belongs to a 

 comparatively small section, characterized by having a 

 very small number of flowers, rarely only one, in each 

 head. Without close examination, the flower-heads of 

 S, tanguticus might be taken for separate flowers, with 

 three or four petals each. 



A dried specimen of 8, tanguticus was first sent to Kew 

 in 1886, by Dr. A. Henry, who collected it near Patung, 

 in the Province of Hupeh ; and he subsequently sent 

 numerous specimens from various other localities in the 

 same Province. In 1887, Kew received specimens of the 

 same species, collected by the Rev. E. Faber, at an 

 elevation of four thousand feet, on Mount Omei, in the 

 Province of Szechuen. Mr. Hemsley, failing to identify 

 these specimens, from the description of 8. tanguti- 

 cus of Maximowicz, described it under the name of S. 

 Henryi. Since then Kew has received an authentic
