'''''Bromus''''' is a large [[genus]] of the grass family [[Poaceae]] with about 160 species.  Estimates in the scientific literature of the number of species have ranged from 100 to 400.
 +
 +
Commonly known as brome grasses, ''Bromus'' species occur in many habitats in temperate regions of the world, including North America, South America, Europe, Asia, Australia, and Africa.  There is a wide variety between some species, while the morphological differences between others are subtle and difficult to distinguish.  The genus ''Bromus'' is distinguished from other grass genera by the combination of several morphological characteristics, including leaf sheaths that are closed (connate) for most of their length, apicals that are usually inserted subapically, and hairy appendages on the [[Ovary (plants)|ovary]].  The [[Leaf|leaves]] and sheaths can be hairless, sparsely hairy or hairy. The [[inflorescence]] is a loose or open [[panicle]], usually drooping or nodding, sometimes spreading (as in [[Japanese Brome]]).

== Description ==
  −
Commonly known as brome grasses, ''Bromus'' species occur in many habitats in temperate regions of the world, including North America, South America, Europe, Asia, Australia, and Africa.  There is a wide variety between some species, while the morphological differences between others are subtle and difficult to distinguish.  As such, the taxonomy of the genus is complicated.  The genus ''Bromus'' is distinguished from other grass genera by the combination of several morphological characteristics, including leaf sheaths that are closed (connate) for most of their length, apicals that are usually inserted subapically, and hairy appendages on the [[Ovary (plants)|ovary]].  The [[Leaf|leaves]] and sheaths can be hairless, sparsely hairy or hairy. The [[inflorescence]] is a loose or open [[panicle]], usually drooping or nodding, sometimes spreading (as in [[Japanese Brome]]).
     −
The [[caterpillar]]s of some [[Lepidoptera]] use ''Bromus'' as a foodplant, e.g. the [[Chequered Skipper]] (''Carterocephalus palaemon'').

== Taxonomy ==
  −
[[Taxonomy|Taxonomists]] have generated various classification schemes to reflect the morphological variation that is seen in ''Bromus''.  In North America, five [[section (botany)|section]]s are generally recognized: sect. Bromus, sect. Genea, sect. Ceratochloa, sect. Neobromus, and sect. Brompsis.  Sections Bromus and Genea are native to the Old World (Eurasia), but many species are introduced into North America.  Sections Bromopsis, Neobromus, and Ceratochloa have several native species in North America.
