Diagnosis and Affimty. 

 This plant is commonly classed with Hierachim pUoselln 

 and Aparglu hispida. With these two it might most readi- 

 ly be confounded. But //. pihsclla is distinguished by 

 trailing shoots, — by its entire, more strongly ciliated leaves, 

 having their under-surface set with a white tomcidum^ — 

 by its citron-yellow flowers, the lower parts of which are 

 of a bright red, and which, upon the whole, are much lar- 

 ger than the flowers of Thrincia ; — finally, by its simple, 

 hairy pappus. Apargia hispida has runcinate leaves, the 

 hairs of which are universally divided into a forked shape. 

 In the centre, not at the sides of these leafy plots, arise, pret- 

 ty perpendicularly, the flower-stalks having each one blossom, 

 and more strongly ciliated. The calyx is covered by strong 

 hairs, scaly, and the scales lie like tiles on one another. The 

 flowers are larger than those of Thrincia, and of a darker yel- 

 low ; each floret lias a bush of loqg yellow hair at the en- 

 trance of the tube, and the five teeth of the upper extremity 

 have five brown glands on their lower surface. In other re- 

 spects the lower surface of the florets is of the same colour 

 as the upper. The pappus is ovate and pinnated. In 

 the south of Europe there grows a species, Avhich is 

 uncommonly like this, namely, Thrincia hispida Roth. 

 This is distingiiished by its annual root, — by its runcinate 

 leaves, every where furnished with forked hairs, — by its 

 roughly ciliated calyx and long-stalked pappus. There 

 grows also in the south of France and in Italy, a Thrincia 

 tuberosa De Cand. Sav., which is distinguished by its beet- 

 shaped tuberous roots, its runcinate, nearly smooth leaves, and 

 by its calvx being but slightly ciliated. Its florets also are 

 discoloured on the back. Apargia iuhcrosa Wilkl. does not 

 altogether correspond with this, but the following more an- 

 cient synonymes are applicable to it : Cichorium Constanti- 

 nopolifanum, Mattli. cd. Bauh. 388. ; Dens Lconis Monspcli- 

 ensiinn, Dodon. 636. ; Monspeliensium dens Lconis, asphode-
