 I have gathered it on the coast of the Mersey, above Liverpool ; 

 and have received it from the rocks at Doun, near Bamff. Se- 

 veral Scottish situations are mentioned by Dr. Hooker. 



Perennial. July, August. 



Abundantly distinct from the last, to which Hudson referred it, 

 notwithstanding the excellent description and remarks of Dille- 

 nius. The thick, woody, long-enduring root runs deep into the 

 ground, producing a number of procumbent, branched, leafy, 

 smooth, angular, hollow siems, spreading circularly on the ground, 

 often tinged with purple. Leaves crowded, sessile, of a dark 

 shining green, fleshy, doubly pinnate, with short blunt segments, 

 destitute of any terminal point, or minute bristle ; they are con- 

 vex on both sides, but especially at the back. Fl. not quite so 

 broad as those of P. inodorum, for though the very convex, yel- 

 low or reddish, disk is often broader than in that species, the 

 white rays are shorter. Calyx-scales bordered with a very nar- 

 row, brown or blackish membrane 3 the outer ones acute; inner 

 rounded, but not dilated, nor furnished with any additional scale. 

 Seeds crowned with a cup-shaped, deeply four-lobed, cartilagi- 

 nous rather than membranous border, especially 2 or 3 rows of 

 the outermost, which seem to have belonged to radiant florets, 

 the seeds in the middle of the disk having smaller, more unequal, 

 borders. This part is not so well represented in Engl Bot. as 

 it ought to have been. The whole herb is slightly aromatic.
