Root rather small, tapering. Stem erect, round, leafy, branched 

 alternately in the upper part, and somewhat corymbose. Leaves 

 all perfoliate in a remarkable degree, alternate, broadly ovate, 

 scarcely pointed, rather glaucous, often purplish at the margin, 

 as the stem is in the lower part. Umbels terminal, compound, 

 solitary, of about 6 general rays, and rather more, very short, 

 partial ones. Partial bracteas large, thrice as long as the flowers, 

 ovate, ribbed, yellowish-green, each with a minute bristly point. 

 Fl. of a full yellow, with remarkably short petals.

 virtues, whether ever experienced or not, are recorded in old 

 herbals only.
