The palm-like ( Arecales ) are an order of the commelinids within the monocotyledons .
features
The representatives have monopodial growth, the plants are without branches . The trunk is often well developed and woody . The roots have vessels . The cuticular wax is designed as a bundle of sticks. The stomata are tetracycline. The leaves are arranged in a spiral. The flowers are more or less sessile. Septal nectaries occur. Per carpel there is a basal sitting upright ovule . Their outer integument is usually more than six layers of cells thick. The fruit is a closing fruit .
Systematics
For a long time only the Arecaceae were counted among the Arecales. The closest relatives of the Arecaceae were long unclear, even if the Dasypogonaceae were often assumed to be the closest relatives. It was not until 2016 that the latter family was finally placed among the Arecales by the Angiosperm Phylogeny Group .
The Arecales are one of the four orders of the Commelinids . They are the sister group of the remaining three orders, Poales , Commelinales and Zingiberales .
The Arecales are a monophyletic group and consist of the following two also monophyletic families:
- Arecaceae (palm family)
- Dasypogonaceae
