Grows to the same 15cm height (up to 40cm) as do Broad-Fruited Cornsalad and Narrow-Fruited Cornsalad.

A one pence coin for size comparison (but the flowers are nearer the camera than is the coin). The florets are lax (not hustled together).

Growing shoulder to shoulder. [Other plants in evidence around the periphery]

But the plants are so closely spaced here that there is little room for them to sprawl all over the ground.

Hairy-fruited Cornsalad is always hairy. The hairs ar on the edge of each of the 4 corners of the square stems, short and angled at ~45° downwards.

Some petals have a pink tinge, especially noticeable on petals curled up in a ball at the top and are yet to open.

All Cornsalads have 3 anthers and 3 styles (although they may not all be visible in these photos).
The flowers are in small umbels of umbels of umbellets, as is usual for Cornsalads (but some cornsalads have many more florets in flowerhead and which may be much more crowded together). The leaf in the foreground also has short hairs on the edges, as do the pointed sepal teeth.

Some fruiting specimens, in a much paler shade of green (sometimes brown).

The fruit capsules can be either hair, or not hairy. The specimens without hairs (as here) seem to have a larger mouth opening than those specimens where the fruits are hairy. The mouth opening of the fruit capsule has short points on its periphery. The two seeds within, one fertile the other sterile, can ge 'seen' loitering at the slightly expanded bottom half of the tubes by their shadows through the almost translucent outer containers.

The seed containing tubes have an opening which is 'sliced at an angle' which has 6 teeth of un-equal lengths (or so the book says, but to your Author they all look very short teeth of about equal length here...).

One of the 5 sepal teeth is much longer than the other 4. The calyx itself (including sepal teeth) is between 0.7 to 1.3mm long.

The browned plants with pairs of ripe and sterile fruits still lurking about.


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 may give you a clue as to which species of Cornsalad it might be.
