Spear-leaved Orache

Spear-leaved Orache - Atriplex prostrata

Description

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.

Similar Species

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.

Identification difficulty

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.
