The Boryaceae are a family of plants from the order of the asparagus-like (Asparagales). The small family contains only twelve species in two genera that occur exclusively in Australia .

description

The species of the Boryaceae are perennial herbaceous plants with a bushy habit, occasionally deciduous and parallel-veined. In their shape, the species of the family are specially adapted to dry environments. The rhizome is short, the sometimes tap root-like, mycorrhizal roots are fibrous and wiry. The numerous linear leaves are spiral-shaped, sessile and divorced. Your endodermis is badly thickened.

The of bracts surrounded inflorescence is a terminal grape or ear , the small, but noticeable, white and durable florets consist of six bloom cladding in two threefold petal circles. The anthers that have grown together at their base on the stamens are almost as wide as they are long. The stylus are thread-like, the scars tiny. The ovary is on top.

Nectar is produced, flies are known as pollinators for Borya . The fruits are capsules , they contain few black seeds.

In both genera there are cells with raphids ( needle-shaped calcium oxalate crystals ). The basic chromosome number is 11 ( Alania ) or 14 or 28 ( Borya ).

Paleobotany

The oldest members of the family are estimated to be around 109 million years old.
