The flowers are tiny, white with 5 actinomorphic petals, in small groups of groups of groups of groups (and possibly more beside).

Those lacking petals are un their way to becoming fruits.

These flower 'umbels' have but few flowers/fruits (both are present here, the larger ones now without petals are the developing fruits). The flowers are white but there may be specimens which have a faint azure hue(?). All cornsalads have flowers with 3 stamens and 3 stigmas; only a few can be seen here.

The stems grow erect and almost straight and reach up to 15cm (up to 40cm occasionally). The leaves are in opposite pairs and are narrow-lanceolate.

The inflorescence atop each branch is umbellate-like, but with only a few rays supporting but few flowers which are arranged with a bit of space around them in a lax manner. Here the flowers have turned to fruits, which is the main way of being sure of the identity to Cornsalads.

The fruits are ovoidal with a bit of a beer-belly on one side. They have a small, short and tube-like opening at the top which is 0.5 to 1mm long. The tiny opening at the summit is cut somewhat jaggedly at an angle. This fruit shape is unique to this species of Cornsalad and measures 1.5 - 2.5mm long, 1 to 1.5mm wide and 1.5 to 2.5mm broad. The fertile cell within lacks a spongy wall. There is also a sterile cell which is slightly bigger than the fertile cell. Where the two meet they are almost impercerptibly grooved.

The fruit on the left is that of this plant; [the other smaller fruit on the right is of Narrow-fruited Cornsalad - which can be either hairy or glabrous as here].


Not to be semantically confused with : Cornflower (Centaurea cyanus), Corncockle (Agrostemma githago), Cornish Bugle (Ajuga genevensis), Corn Chamomile (Anthemis arvensis), Corn Brome (Bromus squarrosus), Corn Cleavers (Galium tricornutum), Corn Marigold (Glebionis segetum), Corn Mint (Mentha arvensis), Corn Parsley (Petroselinum segetum), Corn Buttercup (Ranunculus arvensis), Corn Spurrey (Spergula arvensis), Corn Mignonette (Reseda phyteuma) nor with Salad Burnet (Poterium sanguisorba) [plants with similar names belonging to differing families].

Uniquely identifiable characteristics

Distinguishing Feature : Apparently only the seeds are dead-giveaways for which species it is, although there are some other physical differences between some of the Cornsalads that should give you a clue as to which species of Cornsalad it might be.
