brous, and glaucous or bluish. Leaves 

 very stiff, broad, and sinuate, more 

 or less divided into 3 broad, short 

 lobes, elegantly veined and bordered by 

 coarse, prickly teeth ; the radical ones 

 stalked ; the others clasping the stem 

 by their broad bases. Heads of flowers 

 nearly globular, of a pale blue, with an 

 involucre of 5 to 8 leaves, like those of 

 the stem, but much smaller and nar- 

 rower, the bracts within the head di- 

 vided into 3 prickles. 



On the seacoasts of the whole of Eu- 

 rope and western Asia, except the ex- 

 treme north. Abundant on the maritime 

 sands of England, Ireland, and southern 

 and western Scotland, and has been 

 found as far north as Shetland. Fl, 

 summer, rather late.

2. Field Eryngo. Eryngium campestre, Linn. (Fig. 395.) 

 (Eng. Bot. t. 57.) 



Stems not so thick, and more branched 

 than in the sea F. ; the leaves much 

 more divided ; the segments pinnate, 

 with lanceolate lobes, waved and coarsely 

 toothed, bordered and terminated by 

 strong prickles. Heads of flowers more 

 numerous and smaller ; the involucral 

 leaves more or less pinnately toothed; 

 the scales or bracts within the heads 

 narrow, and mostly entire. 



In fields, waste places, and roadsides, 

 in central and southern Europe, extend- 

 ing eastward to the Caucasus and Ural, 

 and northward to Denmark. Rare in 

 Britain, and believed by some to be an 

 introduced plant ; among several sta- 

 tions formerly given, it is now only 

 known near Plymouth, on the ballast- 

 hills of the Tyne, and near Waterford, in 

 Ireland. Fl. summer.
