both in the text, where he speaks of " petalis barbatis," and in 

 the figure cited for the plant. Moreover, in certain cultivated 

 forms the bearded condition of the petals tends to disappear. In 

 var. agg regains, which is certainly to be referred to this species, 

 Sweet says " the limb is of a bright crimson when first expanded, 

 afterwards changing to a dark purple, and marked towards the 

 base with a darker irregular patch, bearded with a few long 

 scattered hairs." Besser described a D. pseudobarbatus, referred 

 to by Ledebour (Fl. Kossiea, i. p. 277) ; but his own specimens, 

 which are at Kew, seem to have been incorrectly described ori- 

 ginally, and do not differ anywise from D. barbatus itself.

The authors of some of the Austrian floras have joined this 

 species with D. polymorphic considering them as identical; but, 

 as Boissier points out, they are very distinct plants. Its affinity 

 with D. stenopetalus is much more marked.
