Very similar in uprightness and in the sparsity of flowers in each group to Broad-Fruited Cornsalad. The plant reaches up to 15cm (up to 40cm occasionally). But the subtended angle of the first fork in the stem is much greater than is that for Broad-Fruited Cornsalad (at least in this specimen). The leaves are similar too, but may be a little wider in Narrow-fruited Cornsalad(?). |

The flowers are mostly white and in well-separated very-small groupings. But the inflorescences can instead be dense, so this feature is not diagnostic, as many features are not on Cornsalads. |

It is the fruit which are diagnostic on all Cornsalads. Narrow-fruited Cornsalad has a similar gourd-shape as do the fruit of Broad-Fruited Cornsalad, apart from the longer neck which also flares slightly outwards and has more teeth around the periphery. |

Specifically, compared to the similar Broad-Fruited Cornsalad, the fruit can be slightly shorter at 1.5 to only 2mm long, a more slender 0.6 to 0.8mm wide and a slimmer 0.7 to 1.2mm broad. The fertile cell has a spongy wall (not spongy on Broad-Fruited Cornsalad) and the sterile cells are collapsed to just 2 abaxial ridges. |

There is usually one flower in the very first bifurcation which usually turns to fruit before the other flowers have, but the flowers at the tops have caught up here and also turned to fruit. |

The stems are, as usual for Cornsalads, square(ish) and ribbed/fluted (take your pick). |

Two fruits belonging to differing Cornsalads, the smaller fruit on the right is from Narrow-fruited Cornsalad [the larger fruit on the left is from Broad-Fruited Cornsalad] |
Not to be semantically confused with : Cornflower (Centaurea cyanus), Corncockle (Agrostemma githago), 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.
