Stems stout, erect, corymhosely or paniculately branched, marked 

 with two longitudinal elevated lines. Leaves oblong, more or less 

 thickly marked with small pellucid dots, and having the principal 

 nerves also pellucid, appearing as semi-transparent lines when 

 viewed against the light, but not anastomosing. Mowers numerous, 

 in small dense cymes arranged in a rather lax corymb or short 

 panicle. Sepals sUghtly unequal, lanceolate, acute, entire, or with 

 very inconspicuous cartilaginous denticulations towards the apex, 

 nearly destitute of black dots. Petals generally furnished with 

 black dots. Styles as long as the capsule. Capsule with each valve 

 having 2 vittce or bauds containing essential oil on the back.

In bushy places and in hedgebanks and chalky hills. Common

Stem 1 to 3 feet high, emitting roots only at the A^cry base, 

 erect or ascending, wiry, each internode furnished with two opposite 

 elevated lines, one coming from the base of each of the leaves 

 which spring from the apices of the internodes, and which conse- 

 quently change sides at each node. Leaves \ to IJ inch long, 

 varying much in breadth and in the number of pellucid dots. 

 Lateral branches generally numerous, ascendin;?, the upper ones 

 terminating in small compact cymes of bright yellow flowers, about 

 1 to 1 J inch across ; these cymes are generally arranged in a corymb, 

 but sometimes form a short panicle, the diflVrcncc depending on
