Root fasciculated ; the fibres large and thick, some of them larger at the

striated, becoming smaller and bracteiform upwards.

Introduced into the gardens of this country from Canada 
in the year 1823, by Mr Goldie, who sent me the plant here 
figured from his garden at Monkwood Grove, Ayr, in Au- 
gust ; and by Mr Cleghorn, whose plant flowered in our 
Botanic Garden at the same season of the year. It is not, 
however, confined to the more northern parts of America : I 
have long ago received fine specimens from my friend Mr
