The habitat of this plant is waste places. This Melilot is not native. The plant is erect. The leaflets are inversely heart-shaped or oblong, coarsely toothed, the uppermost lance-shaped. The stipules are awl-like, entire. The flowers are pale-yellow or white, in long racemes, with the wing and standard equal and exceeding the keel.

The plant is 1-3 ft. high, flowering from June to August, and is a herbaceous biennial.
The habitat of this plant is shingle beaches and ballast heaps. The stem is short, prostrate, then ascending, spreading, softly hairy. The leaflets are inversely heart-shaped, softly hairy. The stipules are ovate, acute, with small teeth. The flowers are cream-coloured, small, in rounded heads, terminal, and stalked. The calyx is large in fruit, 10-veined, hairy, the teeth awl-like, from a broad base, spreading like a star (hence stellatum), longer than the corolla, which is spreading in fruit, 3-veined and netted, the throat closed with hairs. The plant is 4-12 in. high, flowering from June to August, and is a herbaceous annual.
This is an introduced species found in waste places. The stem is prostrate or ascending. The leaflets are inversely ovate, minutely toothed. The stipules are awl-like to lance-shaped, from an ovate base. The flowers are in hemispherical heads, which become round at length, on axillary short stalks, small, reversed in position, cream or rose colour. The bracts are very small. The calyx is smooth or hairy above, in fruit is inflated, membranous, netted, woolly. The pod is included.
There are 2 seeds. The plant is 4-9 in. in height, flowering in July and August, and is a herbaceous annual.
The habitat of this plant is woods, bushy places in S. Europe, and in England waste places, being a casual in sown grass and clover fields, roadsides and fields, where it is established here and there. The habit is erect. The leaflets are narrowly inversely ovate, the central petiolule not longer than the lateral. The stipules are oblong to lance-shaped, not enlarged below. The flowers are deep yellow, and turn brown, in oval, dense heads with 50 florets, the stalks axillary, as long as, or longer than, the leaves. The florets are at length turned back. The standard is enlarged, striate, larger than the pod. The style is nearly as long as the pod. The plant is 4-12 in. high, flowering from June to September, and is a herbaceous annual.
The habitat of this plant is cultivated fields, ballast hills, or fields. The habit is climbing, the stems being winged, with one pair of linear - lance - shaped leaflets, the leaves not being so long as the flower-stalks. The flowers are purple, 2 on each flower-stalk. The standard is crimson. The pods are hairy, with bulbous hairs, or silky, the 8-10 seeds being covered with wart-like knobs. The plant is 2-4 ft. high, and flowers in June and July, being annual, herbaceous.
The habitat of this plant where it is native is bushy places. The leaflets are linear to lance-shaped. The leaf-stalks have one pair of leaflets and a tendril. The flower-stalks bear 1 flower, with a long point not so long as the leaf-stalk. The seeds are rounded.
In England this species is an escape from gardens, found rarely in waste places. The habit is that of a climber. The stem is winged. The leaves are large, elliptic, bluish - green, with one pair of leaflets. The stipules are broad, protecting the leaflets. The flowers are purplish-rose. The hilum one-third encircles the seed. The plant is 3-6 ft. high, flowering from June to August, and is a herbaceous perennial.
