Umbellated Plants. • 
In their general habits and appearance these plants 
exhibit a striking resemblance, and are therefore asso-

involucrum or are destitute of that appendage.

flowers in heads ; common receptacle, conical, chaffy. 
Eryn. JSlariiirnum^ Sea-holly ; with radical leaves, 
roundish, folded, and spinous ; flower-heads, with foot- 
stalks ; perennial ; flowers in July and August, and is 
common on sandy shores. 
Eryn. Campestre ; with leaves embracing the stem, 
somewhat pinnated, and deeply cut; is also perennial ; 
flowers in July and August, and is found, but more 
rarely, in pastures near the sea.
