Spear-leaved Orache
Spear-leaved Orache - Atriplex prostrata
Spreading, prostrate to erect, medium tall plant. Green mealy when young often reddening with age. Leaves arrow shaped generally not mealy, with the basal lobes at right angles to the stalks. Flowers in fairly dense panicles, leafy below. Fruits enclosed in triangular toothed bracts.
Atriplex patula. Other aliens species may occur, and if in doubt, the key in Stace (4th edn.) should be referred to.
Goosefoots (Chenopodium) are quite similar, and young plants can be difficult to determine.
All Atriplex have the fruits enclosed by two enlarged bracteoles.
Lower leaves triangular or spear-shaped. Bracteoles fused at base only, for less than a quarter of the way.
Photos must show ripe fruits enclosed in bracteoles, and lower leaves
Arable land, waste places, disturbed ground, coastal habitats and shingle. Often by roadsides, in the salt-splash zone
July to October.
Annual.
Quite common in England south of the Humber, coastal elsewhere.
Fairly frequent in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in 238 of the 617 tetrads.

Peronospora farinosa s. lat.
Peronospora farinosa can cause yellowish swellings on the leaf blade of the host plants in the family Amaranthaceae, such as Fat-hen and Oraches, often affecting several leaves of the same plant. The affected leaves can become swollen and slightly distorted. This downy mildew can also have a purplish tinge.
