Distribution: ―Native. In México B. anomalus is known from the states of Aguascalientes, Baja California Sur, Chiapas, Chihuahua, Coahuila, Distrito Federal, Durango, Guanajuato, Hidalgo, Jalisco, Estado de México, Michoácan, Morelos, Nuevo León, Oaxaca, Puebla, Querétaro, San Luis Potosí, Tamaulipas, Tlaxcala, Veracruz and Zacatecas (Fig. 4). It is present in Guatemala in the states of Solola and Quezaltenango, and in Costa Rica in the states of Cartago and San José (Fig. 4). Bromus anomalus extends north into western Texas (Pavlick & Anderton 2007) and has also been reported for New México (Allred 1993).
Ecology: —This common species occurs in the mountains in pine-oak forests on slopes, forest margins, along creeks and ravines, and on rock outcrops, often in calcareous soils; associated with Pinus durangensis Martínez (1942b: 23), P. cembroides Zuccarini (1832: 392), P. rudis Endlicher (1847: 151), P. teocote Schlechtendal & Chamisso (1830: 76), P. chihuahuana Engelm. in Wislizenus (1848: 103), P. johannis Robert-Passini (1978: 366), P. ayacahuite C.

(1819: 278), Agave montana Villareal-Quintanilla (1996: 191), Physocarpus Cambessèdes (1824: 239) Rafinesque (1838: 73), Ceanothus Linnaeus (1753: 195), Garrya macrophylla Bentham (1840: 50), Quercus sideroxyla Bonpl. in Humboldt et al. (1809: 39), Q. emoryi Torr. in Emory (1848: 151), Arbutus xalapensis Kunth in Humboldt et al. (1819: 279), A. arizonica (Gray 1886: 317) Sargent (1891: 317), Cercocarpus montanus Rafinesque (1832: 146) and C. ledifolius Nutt. in Torrey & Gray (1840: 427). Elevation: 3440–3630 m (Costa Rica), 2100–3200 (Guatemala), (790–) 1000–3710 m, usually> 2000 m (México); sites at elevations below 2000 m are mostly in Coahuila, Nuevo León and Tamaulipas.
Common Names: ― México brome, nodding brome (English); bromo dormilon (Spanish).
Comments: ― Bromus anomalus is the most common and widely distributed species of section Bromopsis in México, where it is used as fodder (Saulés & Dávila Aranda 1992). The species was not reported for Guatemala by Swallen & McClure (1955) or Soderstrom & Beaman (1968), but was reported there by Pohl & Davidse (1994); they cited Smith 658, as we do here, along with another collection from Guatemala.
Bromus anomalus is the smallest species of sect. Bromopsis in Mexico. Larger individuals of B. anomalus may be confused with B. richardsonii. It can be distinguished from B. richardsonii by its awns 1.2–3 mm long [vs. 3–6.5 mm long], auricles usually present [vs. absent], lemmas 7–10 mm long [vs. (9–)10–13.5(–15) mm long] and blades 2–4 mm wide [vs. (3–)4–9(–13) mm wide]. Acollection from Nuevo León (Peterson et al. 16765) with broad leaves (up to 6.5 mm wide), long lemmas (up to 13 mm), awns up to 4 mm long, pubescent lemmas and glumes, and auricles better fits B. richardsonii, but we keep it here based on the presence of auricles, which we have not seen in material of B. richardsonii. The extreme lengths of the longer awns, longer lemmas and broader leaves observed in this specimen are not included in the key or description, because its placement in B. anomalus is uncertain.
On 6 October 2000 the second author was accompanied by two Tarahumara (Gustavo Arturo Palma Aguirre and Juvencio Antonio Bustillos Ramirez) on a short foray along the edge of the Barranca Río Verde (P.M. Peterson, J. Cayouette, G.A. Palma Aquirre & J.A. Bustillos Ramírez 15372) to collect B. anomalus seed (basiáhuari) used to begin the fermentation process to make a corn drink called tesquino (Kennedy 1963). This differs from the species Saulés & Davila Aranda (1992) reported for this purpose (B. carinatus).
Taxonomic status of Bromus meyeri — Bromus anomalus is a morphologically variable taxon. Individuals typically have hairy lemmas throughout most of the species’ range. Individuals with lemmas glabrous or puberulent from the mountains of Nuevo León and Tamaulipas were described as B. meyeri by Swallen (1950), from a collection gathered at Dulces Nombres, Nuevo León. Aside from noting B. meyeri to be a taxon with auricles and stating, incorrectly, that B. latiglumis (Scribner ex Shear 1900: 40) Hitchcock (1906: 211), a Canadian/ U.S.A. taxon that does not occur in México, is the only other known species of Bromus to have auricles at the mouths of the sheaths, he did not provide a diagnosis of his new species. Two years after its description, Wagnon (1952) treated B. meyeri as a synonym of B. anomalus, as have some recent authors (Pavlick 1995, Clayton et al. 2002 onwards). Bromus meyeri was recognized by Soderstrom & Beaman (1968), who suggested it to be most closely related to B. texensis (Shear 1900: 41) Hitchcock (1913: 381), a rare species from southern Texas (Pavlick & Anderton 2007); B. anomalus differs from B. texensis by its longer awns, fewer-flowered spikelets, shorter glumes and lower sheaths short-pilose (vs. villous). Soderstrom & Beaman (1968) did not mention its similarity to B. anomalus. In their key, B. anomalus and B. meyeri are separated by lemma pubescence: "lemmas glabrous, scabrous, or inconspicuously short hirsute" in the lead to B. meyeri, and "lemmas villous over the back or along the margins" in the lead to B. anomalus. Bromus meyeri has also been recognized by Beetle (1977, 1987), Espejo- Serna et al. (2000) and Pavlick et al. (2003), all without comment.

We have studied plants in the field, including in the vicinity of the type location, and herbarium, and we agree with Wagnon (1952) in treating B. meyeri as a synonym of B. anomalus. Although many collections from the Sierra Madre Oriental in Nuevo León have lemmas that are variously glabrous to puberulent (e.g., Peterson, Valdés- Reyna & Sosa Morales 16699, 16703, 16756, 16760, 16763, 16768, 16780, 16783, Peterson & Valdés-Reyna 15872, Peterson & Saarela 21100, Mueller & Mueller 428, 1168, Harvey 987) or have short pubescence (e.g., Peterson & Saarela 21073, 21102)—character states not found elsewhere throughout the range of B. anomalus —the plants otherwise fall within the range of variation of B. anomalus. Plants with densely pubscent lemmas are also present in the same areas (e.g., Peterson & Valdés-Reyna 15824, 15891; Peterson, Saarela & Flores Villegas 21373; Peterson, Valdés-Reyna & Sosa Morales 16753, 16765, 16778; Peterson & Valdés-Reyna, Peterson & Saarela 21103; Mueller 2290; Mueller & Mueller 424, 425, 1058, 1078). Other specimens are intermediate, with dense pubescence along the margins and lemma backs glabrous to puberulent (e.g., Peterson & Valdés-Reyna 15863, 15889). We consider plants previously recognized as B. meyeri to be a local form (in the nontaxonomic sense of the word) of B. anomalus, consistent with varying lemma pubescence found in several other Bromus species, including B. exaltatus and B. richardsonii.
Distinguishing Bromus anomalus and B. porteri (Coulter 1885: 425) Nash (1895: 512) — Bromus anomalus and B. porteri have long been confused in North America. Bromus porteri has been variously recognized as a distinct species (Wagnon 1952, Pavlick 1995, Pavlick & Anderton 2007, Saarela 2008, Saarela & Peterson 2012) or as a synonym of B. anomalus (Kearney & Peebles 1960, Hitchcock et al. 1969, Jones et al. 1997, Douglas et al. 2001), and the characters used to distinguish these taxa have not been applied consistently. Hitchcock (1913) recognized only B. porteri in México. Wagnon (1952) distinguished B. anomalus from B. porteri by lower glumes 1- or 3-nerved [vs. consistently 3-nerved], auricles usually present on lower leaves [vs. absent] and the midrib of the culm leaves tapered just below the collar [vs. not tapered just below the collar]. By these criteria, he did not consider B. porteri to be present in México. By contrast, Soderstrom & Beaman (1968) recognized both B. anomalus and B. porteri in México, and their circumscription of the species was different than that of Wagnon (1952). They treated plants with 1-nerved lower glumes, awnless upper glumes and lemmas usually obtuse as B. anomalus, and plants with 3-nerved lower glumes, upper glumes awn-tipped and lemmas acute or bifid at the apex

as B. porteri, further noting that some specimens have unusual features. Subsequent to the revision of Soderstrom & Beaman (1968), both taxa have been recognized in México (Beetle 1977, 1987, Gould & Moran 1981, Rivera & Aranda 2004).
We find the character states used by Soderstrom & Beaman (1968) to be intermixed among specimens, and conclude that they cannot be used to distinguish two taxa. Our circumscription of taxa follows that of Wagnon (1952), which has been utilized in recent treatments of Bromus in North America (Pavlick 1995, Pavlick & Anderton 2007, Saarela 2008, Saarela & Peterson 2012). By these criteria, we have seen no specimens of B. porteri in México. Bromus porteri is distributed in western North America from Manitoba to British Columbia and south to California and New México (Pavlick & Anderton 2007).
