Root fibrous, with woody somewhat creeping underground stems, 
the whole plant smooth. Stems mostly several, erect, acutely four 
angled, smooth, often pinkish, leafy, about two feet high, mostly 
much branched with short axillary leafy branches. Leaves ovate, 
pale bright green above, glaucous beneath, and scattered over with 
small pellucid dots, opposite, sessile, veiny, the margin more or less 
profusely beset with dark glandular dots, secreting a pink fluid. 
Inflorescence a terminal sub-corymbose panicle of numerous lemon 
coloured flowers. Calyx of five equal entire lanceolate segments, 
smooth, veiny. Petals oblong, oblique, sometimes dotted or striated 
with dark purple. Styles short, erect, three. Capsules oblong, 
smooth, three celled, many seeded. 
Habitat—Moist pastures, meadows, and thickets, by the side of 
rivulets. 
Perennial; flowering in July and August. 
Readily distinguished from the following species, by its narrow 
lanceolate calyx segments and dotted leaves. It is very variable in 
size, according to the kind of soil in which it has grown; if dry and 
arid, it is a simple erect unbranched stem, about a foot high. If it 
has grown ina wet soil it is branched from the axis of every leaf, 
and is a stout plant, about two feet high ; but in its specific character 
it is constant.
