Botanical Description

These are annual or perennial herbs and shrubs, mostly bare, only a few species are soft-haired. Quite a few representatives of the family are tree vines (species of the genera Gugonia ( Hugonia ), Durandea ( Durandea )) climbing through hook-shaped spikes (metamorphosed lower branches of the inflorescence), twisted like sheep’s horns ^[2] .

The leaves are alternate and only in Radiola and Linum catharticum are opposite or whorled, whole, sessile, without stipules.

The correct bisexual flowers are collected in racemose or paniculate inflorescences. Five sepals (four in Radiola ); five petals ( Radiola has four); there are also five stamens, fused with the bases of the threads in one bundle. Pestle one, with five, four stigmas (for Radiola ) and with an upper five- or four-nest (for Radiola ) ovaries ; each nest is divided by a false septum in half and in each half of the nest there is one ovule.

Flower formula : $\ast K_{5}\;C_{5}\;A_{10\;or\;{5+{5^{st}}}}\;G_{({\underline {5}})}$ ${\ displaystyle \ ast K_ {5} \; C_ {5} \; A_ {10 \; or \; {5+ {5 ^ {st}}}}; G _ {({\ underline {5}}) }}$ .

The fruit is an almost spherical box opening on the partitions. The seed contains a direct fleshy embryo and poorly developed protein.

Flaxseeds are found in temperate and warm climates of both hemispheres; in European Russia there are two genera: Radiola Hill and Linum L. - the common flax also belongs to the latter.
