Plants by habit

Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as true grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. Poaceae is the most well-known family within the informal group known as grass.

The term is used in botany and in vegetation ecology especially in relation to grasslands and understory. Typically, these are eudicots without woody stems.

Psammophytes are commonly found growing on beaches, deserts, and sand dunes. Because they thrive in these challenging or inhospitable habitats, psammophytes are considered extremophiles, and are further classified as a type of psammophile.
