It grows erect to 25cm high, but often much less.

It is branched, the branches being irregular.

The leaves are between 4 and 10mm long, with the topmost not growing above the clusters of flowers.

The flowers here have not opened; when they do there will be usually be 5 to 7 flowers. The flowers will be enclosed by several hairy phyllaries; the only visible part of the many florets each contains will be at the end where the observer will find a small tight cluster of yellow florets.
When they mature the 5 to 7 slightly barrel-shaped flowers will form a 5- to 7-spoked radial 'fan' distributed around the top of the stems.

Here the leaves on the stem have turned brown as has the stem.

The yellow flowers are in numerous, well-separated small fan-like clumps.

Well-separated small fan-like tubular(ish) clumps of flowers with the flowers just poking out from the phyllaries which are few in number and in ill-defined rows. All the florets within a set of phyllaries are tubular with the inner florets being bisexual and wider than the outer florets which have wider corollas and are female.

The leaves alternate up the stem. The flowers here may be starting to fruit. The parachute hairs are all simple; the bisexual flowers have a pappus whilst the female flowers may or may not have a one.


Some similarities to : many other Cudweeds such as Jersey Cudweed (Gnaphalium luteoalbum), Highland Cudweed (Gnaphalium norvegicum), American Cudweed (Gnaphalium purpureum), Dwarf Cudweed (Gnaphalium supinum), Heath Cudweed (Gnaphalium sylvaticum) and Cape Cudweed (Gnaphalium undulatum) (this paragraph using their old genera names).

Small Cudweed is native and grows on waysides, sandy heaths, sand-pits and gravelly places throughout most of the British Isles, but is less common in the North and West of the UK and is absent entirely from the Outer Isles.

Small Cudweed used to be in the Filago genus until taxonomists this last decade (2010 to 2020) thought to create a new genus for them when they found a small difference: a rounded protuberance at the base of each phyllary which is absent from the now revamped and pruned Filago genus of Cudweeds. Are they picking at straws? [Your Author has just needed to create 5 new taxa on this website to accommodate all the different re-evaluated 'Cudweeds' that taxonomists have now discerned. If they look hard enough for differences, each plant will soon need its own genus...].
