Poales

Sugar cane ( Saccharum officinarum )

The Süßgrasartigen ( Poales ) are an order of Commeliniden within the monocots.

Description

Often there are grassy, herbaceous plants, mostly persistent. At the shoot axes, the leaves are usually two lines and they are usually parallel-veined. The epidermal cells often have silicate inclusions.

The original taxa of Poales are predominantly wind- pollinated ( anemophily ). The blooms are triple. They often vary greatly reduced flowers bloom cladding spelzenartigen. Nectaries are usually absent.

System

This order contains in older systematic reviews only one family, the grasses ( Poaceae ). Molecular biological studies have, however, led in 1998 to a significant expansion of this order. So now the families of the previous orders Typhales, Bromeliales, Juncales, Cyperales, Restionales and even some other submissions to Süßgrasartigen ( Poales ) are summarized.

The APG III comprises the following order 16 Families:

• Anarthriaceae
• Bromeliad ( Bromeliaceae )
• Centrolepidaceae
• Sedges ( Cyperaceae )
• Ecdeiocoleaceae
• Eriocaulaceae
• Flagellariaceae, with only one genus: Flagellaria

• Joinvillea

• Mayaca

• Typha
• Sparganium
