OJs.— Several other species are sometimes seen in gardens, among which are D. Thapsi, with mullein- 

 like leaves all radical and flat on the ground ; D. leucophcea, with very large, dense, leafy racemes of 

 dusky white fla. Numerous hybrids also occur in gardens, produced between the above species which are 

 often difficult to distinguish.
