The Subclass Commelinidae is further organized into finer groupings including:
- Order (6): Commelinales · Haemodorales · Nymphaeales · Pandanales · Poales · Zingiberales
Orders
Commelinales
Commelinales is the botanical name of an order of flowering plants. It comprises five families: Commelinaceae, Haemodoraceae, Hanguanaceae, Philydraceae, and Pontederiaceae. All the families combined contain over 800 species in about 70 genera; the majority of species are in the Commelinaceae. Plants in the order share a number of synapomorphies that tie them together, such as a lack of mycorrhizal associations and tapetal raphides. Estimates differ as to when the Comminales evolved, but most suggest an origin and diversification sometime during the mid- to late Cretaceous. Depending on the methods used, studies suggest a range of origin between 123 to 73 million years, with diversification occurring within the group 110 to 66 million years ago. The order's closest relatives are in the Zingiberales, which includes ginger, bananas, cardamom, and others. [more]
Haemodorales
Nymphaeales
Nymphaeales is an order of plants, which consists of water lilies and other aquatic plants. [more]
Pandanales
Pandanales is an order of flowering plants, with a pantropical distribution. [more]
Poales
Poales is a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales. [more]
Zingiberales
Zingiberales is an order of flowering plants. The order has been widely recognised by the taxonomists, at least for the past few decades. This order includes many familiar plants like ginger, cardamom, turmeric, galangal and myoga of the Zingiberaceae or ginger family, and bananas and plantains of the Musaceae or banana family, along with arrowroot of the Marantaceae or arrowroot family. [more]
At least 7,562 species and subspecies belong to the Order Zingiberales.
