X HIS fpecies is found in the fame fituations as the D. rotund
folia, though fomewhat lefs frequently, and flowers at the
fame feafon.
In root and general habit it altogether agrees with the
former, differing chiefly in its leaves, which are not depreffed,
but nearly ereft, Handing on long ftalks, and their form ig
exa6tly obovate, not orbicular. For another mark of diftinftion
we are obliged to Dr. Hull, (who has enriched his Flora with
feveral good obfervations on the genus,) that the footftalks of
the leaves in the rotundifolia are hairy; in this and the anglica
they are fmooth, and we find this difference conftant. The
ftyles of the longifolia, according to this author, vary from
6 to 8 full as often as in D . anglica. The petals and ftamina
alfo are frequently 6.
Caulefcent varieties of this and the preceding have been
found by the late Dr. Withering, whofe fpecimens are now
before us, as well as by the prefent worthy botanical Profeflor
of Oxford. Dr. Hull mentions only the longifolia in fuch a
Hate. W e are perfuaded thefe are merely varieties, in which
we are confirmed by the analogy of Garduus, Carlina and Ono~
■ pordum, (fome would add Primula,) in which fpecies that are
truly acaules become caulefcent by luxuriant nourifhnient.
