ERYNGIUM (from ervngion, the old Greek name used 

 by Theophrastus, &o.). Eryngo OBD. UmbelUfera. A 

 genus of hardy or nearly hardy herbs, usually perenni 

 and spiny. It comprises more than a hundred species 

 natives of temperate and sub- tropical regions, tl 

 majority being South American. Flowers congregate 

 into oblong or roundish dense heads; lower bracts 

 usually the largest, and forming an involucre round the 



Eryngium continued. 



head of flowers. Radical leaves, as well as the canline 

 ones, sheathing more or less at the base. Many species 

 of this genus are very handsome plants, and are well 

 suited for growing in borders and in sub-tropical gar- 

 dens. They thrive best in a light sandy soil. Increased 

 by carefully-made divisions, or by seed.

 the upper part of the herb and the flowers, of a beautiful blue 

 colour. July and August. L, radical and lower cauline ones on 

 long petioles, deeply cordate.lserrate-toothed ; upper cauline ones 

 palmately lobed, cihately serrated ; leaves of the involucre ten to 

 twenty, rather soft, a little longer than the head of flowers.

 ceeding in length the head of flowers. A. 1ft. to 2ft. Europe,

E. aquaticum (aquatic), fl. white or very pale blue, in globose 

 heads. July to September. I. broadly linear, with parallel

 August {., radical ones orbicular, tripartite ; lobes pinnatifld or 

 cut in a forked manner, quite entire between the divisions ; 

 leaves of involucre ten to twelve, lanceolate, pungent, erect, 

 much longer than the head of flowers. Stems simple, a little 

 branched at the apex. A. 1ft to 2ft Pyrenees, 1731. Hardy. 

 E. bromelinfolinm (Bromelia-leaved). fl. white, in round 

 heads. July. (. with parallel nerves, bearing large subulate 

 teeth, which are shorter than the breadth of the leaves ; radical 

 ones very long, broadly lanceolate-linear ; involucral leaves ten, 

 lanceolate, exceeding the head of flowers. A. 3ft. to 4ft Mexico. 

 Half-hardy. 



E. campestre (field), fl. blue, in roundish heads. July and 

 August. L, radical ones nearly ternate; segments pinnatifld; 

 lobes ovate; cauline ones auriculated ; leaves of involucre

 eled. A. 1ft. to 2ft. Europe, &c: (Britain). (Sy. En. B. 570.) 

 E. diohotomum (spreading), fl. blue, in globose heads. July

 base, toothed ; cauline ones palmately parted, spreading ; lobes 

 spiny-toothed ; leaves of involucre lanceolate, much longer than 

 the heads of flowers. A. 1ft. to 2ft South Europe, Ac., 1820. 

 Hardy. E. Lasseauxii (R. H. 1874, 375) is closely allied to 

 E. dtcAotomum, but the panicle of reddish-purple flowers is loose.
