On the coast of Elgin. Mr. Brodie of Brodhe. Guillon Links • 

 Mr. Maughan ; shores of the Moray Frith j Mr. D. Don. Hooker. 

 On the Links, south of Bamborough castle, and on Holy Island, 

 abundantly. J finch. On the Weigh coast. Mrs. Douson. 



/3. On the sandy sea shore to the north of Liverpool. Dr. Bostock 

 and Mr. Shepherd. 



Annual. June, July. 



Stems generally about 2 inches high, stout, simple and solitary ; 

 sometimes, especially in the variety (3, there are several together 

 from the crown of the root ; from 3 to 5 or G inches in height, 

 and somewhat forked at the top, like the first species. Leaves nil 

 linear-obovate, obtuse, often roughish at the edges, with an 

 obscure marginal rib at each side, not extending so far as the 

 mid-rib j radical ones very little larger or broader than the rest, 

 which are variously disposed, mostly crowded about the top and 

 bottom of the stem, and an inch long. All the leaves indeed 

 seem liable to vary in breadth, and when they become almost 

 elliptical, there are 2 additional ribs. Ft. rather larger and hand- 

 somer than the foregoing, for the most part sessile, and crowded 

 into a dense head, or a partly forked, compact, corymbose pa- 

 nicle, which last is most usual in /3. Segments of the calyx more 

 or less combined above the base, their edges somewhat, but not 

 uniformly, membranous j they are often minutely downy, some- 

 times 3 -ribbed. As the capsule swells, the tube of the corolla 

 becomes longer than the calyx ; but never till the flower fades. 

 The style is perfectly straight and upright. The variety /3 is the 

 Swedish plant mentioned in Engl. Bot. v. 7. at the bottom of 

 page 458. 



3. E. latifolia. Broad-leaved Tufted Centaury. 



Stem three-cleft at the top. Flowers in dense forked tufts. 

 Calyx as long as the tube. Segments of the corolla lan- 

 ceolate. Lower leaves broadly elliptical, with five or 

 seven ribs. 



Chironia Centaurium ; variety 2nd. Fl. Br. 1393. 



On the sea shore of Lancashire. 



In sandy ground near the sea, to the north of Liverpool. Dr. Bos- 

 tock and Mr. Shepherd. 1803. 



Annual. July. 



Root with many long fibres. Stem solitary, erect, scarcely 3 inches 

 high, leafy j simple below j divided at the top into 3 principal 

 branches, each terminated by a very compact, round, densely 

 forked, tuft, or head, of Jlowers, which are but half the size of 

 E. Centaurium, the segments of their corolla being lanceolate, 

 and much narrower than in either that species or the last. 

 There is now and then a smaller tuft, or two, situated lower 

 down. The leaves, especially the lower ones, are very different
