More

Annual herb, glabrous in all parts. Leaves sessile, simple, opposite, entire. Stipules absent. Inflorescence a dichasial corymbose cyme. Sepals 4, toothed at apex, united at base, persistent. Petals 4. Stamens 4; rarely 4 staminodes also present; filaments united at base with petals. Ovary 4-locular; each loculus partly divided by a false septum, 2-ovulate; styles 4, free; stigmas capitate. Fruit a 4-locular, 8-valved, lobed capsule. Seeds small, ovoid, with little endosperm; embryo straight.

Fruit a 4-locular 8-valved capsule with 2-seeded loculi, the seeds in each loculus partially separated by an enlarged false septum.

Much like Linum, differing mainly in its 4-merous fls, apically cleft sep, and diminutive, freely branching habit. Monospecific.

Ovary 4-locular, each loculus with 2 pendulous ovules and partially divided by a false septum; styles 4, free; stigmas capitate.

Petals 4, white, united with the stamen filaments to form a very short tube, very shortly unguiculate.

Stamens 4, with filaments united at the base only; staminodes usually absent; nectaries obscure.

Flowers in terminal regularly dichotomous dichasia, homostylic.

Leaves sessile, opposite, entire, 1-nerved, exstipulate.

Sepals 4, (2) 3 (4)-fid, united at the base, persistent.

Seeds small, with scanty endosperm; embryo straight.
