On dead sticks of heather in a pool of water, at an 

 altitude of 2200 feet. September and October. 



The stems are simple, varying from 2 lines to J an 

 inch in height, springing from complicated threads, and 

 covered with black-jointed hairs or fibres ; at the junction 

 with the head the stem is less hairy and paler in colour, 

 internally it is solid and greyish- white. The head is 

 flattened orbicular (sometimes concave in the middle), 

 and of a beautiful orange-vermilion in colour ; the 

 margin has a fringe of close appressed hairs of the same 

 character as those on the stem ; underneath the head is 

 paler in colour at the junction with the stem. The 

 species is readily distinguished from its ally, V. trun- 

 corum, by the hairy stems and differently coloured 

 heads (Dr. Buchanan White, I. c.).
