Old and West Hartlepool, occa-

Old and West Hartlepool, rather 
common, 
One of the commonest of ballast- 
hill plants. 
Old Hartlepool, commen. 
Very common on the fresh ballast, 
but I never found it on ballast 
older than three years. 
Old Hartlepool, once common, and 
growing to an enormous height. 
Old and West Hartlepool, rather 
common. 
Old Hartlepool, rare. 
Old Hartlepool, occasional plants. 
I found a large plant on the Old 
Hartlepool ballast-hills five years 
ago. It increased to a magnifi- 
cent little shrub, when it was 
smothered up with fresh ballast. 
I found also two plants this year, 
on the West Hartlepool ballast. 
Another of the commonest plants. 
Old Hartlepool, common. 
Old Hartlepool, common. 
West Hartlepool, on old ballast 
very fine bushes spreading and 
nearly three feet high. 
West Hartlepool. Of this exquisite 
Caucasian plant I found one large 
erect bush about four feet high. 
I counted over a hundred buds 
upon it. The horns of the in- 
volucral scales are, in the early 
bud very well developed, but in 
the flower they altogether dis- 
appear. 
A very common plant on older 
ballast generally accompanied by 
quantities of Artemisia vulgaris. 
Old Hartlepool, common, West 
Hartlepool, less common.
