the length of the tube of the calyx, oval, or oblong-lanceo- 

 late and mucronulate, with the nerves distinctly prominent. 

 The calyx is generally contracted above, with the teeth 7-9- 

 nerved and ciliolate at the margin, and is sometimes as long as 

 30 mm. The lamina of the petal is bearded, though in some of 

 the Western forms this capillary outgrowth is slight, and almost 

 evanescent. The capsule is oblong, substipitate, and slightly 

 exserted.

Thunberg's earlier name, D. scaber, is altogether inappro- 

 priate ; as, besides being insufficiently distinctive, the glabrous 

 form is more frequently met with. The same name has also 

 been used for species (?) described by Chaix and Schleicher.
