They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera.

Several species such as Stipa brachytricha, S. arundinacea, S. splendens, S. calamagrostis, S. gigantea and S. pulchra are used as ornamental plants.

One former species, esparto grass (Macrochloa tenacissima), is used for crafts and extensively in paper making.

It is a coarse grass with inrolled leaves and a panicle patterned inflorescence.

[4] In some areas of the western United States grasses of the genus Stipa form a significant part of the understory of Blue Oak savannas, and were even a more important element prehistorically before the invasion of many European grasses.
