Has two petals, a top hood and a lower lip with three lobes. The hood is a slightly paler yellow than or yellow-green than the deep-yellow lip. The lip has two concolorous lumps on it somewhat reminiscent of those of Common Toadflax (Linarea vulgaris), which it superficially resembles.

The hood has two white or purple-tipped teeth just lurking in the upturned-V-shaped upper part.

The hood, sepals and stems have short glandular yellow hairs which make the plant feel sticky.

The spent sepals, from which protrudes the remains of the now fawnish-coloured organs, have but four long teeth (rather than the usual 5)

Uniquely identifiable characteristics

Distinguishing Feature :

The only plant in its Genus (at least in the UK). It is a Bartsia as is Red Bartsia (Odontites vernus), but that is in a differing genus (although same Broomrape Family, Orobanchaceae) It differs from Red Bartsia in a number of features, the most obvious being that Yellow Bartsiis upright and with yellow flowers on all sides of the usually un-branched stem (whereas Red Bartsia has red flowers, mainly on one side of the arching and usually branching stems).

It is frequent in the South and West of Britain, on damp ground especially near the sea. This is a  Hemi-Parasitic plant, meaning that it relies on obtaining some of its' nutrients from the roots of nearby plants, usually grasses.
