Bromeliaceae
Poaceae. Poales. The earliest fossils attributed to the Poales date to the late Cretaceous period about 66 million years ago, though some studies (e.g., Bremer, 2002) suggest the origin of the group may extend to nearly 115 million years ago, likely in South America.
The earliest known fossils include pollen and fruits. The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in the genus Mayaca, with solitary terminal flowers). The flowers of many species are wind pollinated; the seeds usually contain starch.
Poales. Süßgrasartige. Beschreibung[Bearbeiten] Die ursprünglichen Taxa der Poales sind überwiegend windbestäubt (Anemophilie).
Die Blüten sind dreizählig. Sie haben oft unterschiedlich stark reduzierte Blüten spelzenartigen Blütenhüllblättern. Nektarien fehlen meist. Systematik[Bearbeiten]
