This plant grows to 70cm high and has a fairly unique jizz: the leaves at the top are almost bolt-upright and above any flowers, which are in side-by-side pairs and large!

The flowers at the top are yet to open, and have a pale-green 4--lobed calyx which has rounded (but with a tip at the end) lobes. The folded up flower (which looks like a white boxing glove) fits loosely within the sepal cup. The leaves near the top are bullate (have raised 'blisters' between the veins) whereas those lower down are flatter.

Opened flowers are large, with the corolla being between 25 to 40mm across.

The flowers are zygomorphic, with 5 petals, a hood at the top above the sexual organs, two side-wings, and a longer lower petal which may either have 2 rounded lobes, or may be fused as this floret.

The very short hairs on the petals look as though they have glandular tips (tiny bobbles at the end).

The 4 stamens with cream-coloured anthers are beneath the upper petal as well as an stigma and style somewhere. The corolla can be either white, or shaded pink to mauve, pink to purple. The upper petal has very short hairs, there may be fewer short hairs on the other petals(?).

The sepal cup is pale green, has two lips, the upper one may have 2 or 3 short lobes. and is a very slack fit to the long tubular part of the flower before the petals. A side-view of the 4 anthers and stigma.

The sepal cup is pale green, has two lips, the upper one may have 2 or 3 short lobes. The flowers are in side-by-side pairs. The stem, if you could see it beyond the long hairs that surround it, is square.

Not to be semantically confused with : Bastard Agrimony (Aremonia agrimonioides), Bastard Cabbage (Rapistrum rugosum), Bastard Toadflax (Thesium humifusum) or Tall Ramping-fumitory (Fumaria bastardii) [plants with similar names belonging to differing families].

Some similarities to : the even rarer [RRR] Wood Calamint (Clinopodium menthifolium).

Uniquely identifiable characteristics
