with purple near the base, where they are dilated and 
toothed. Disk epigynous, annular. Stamens 8, alternately 
smaller, each arising from the back of a roundish villous scale;

Found among some of the seed-papers sent from North- 
West America, by Mr. Douglas, on his last expedition, 
and raised in the Garden of the Horticultural Society, where 
it flowers in the middle of summer. _
