Echeverría &amp; G.A. Leofanti 229 (holotype BAL! 317 ;  isotype BA!).</p><p>The new species,  B. alonsae, is similar to  B. catharticus var. catharticus but differs in growth habit (perennial with creeping or semi-creeping habit vs. annual or briefly perennial with erect or semi-erect habit), blade color (glaucous green vs. light green), blade pubescence (short and dense vs. variable to glabrous), vernation (folded to rolled vs. rolled), and flowering period (mid-October to late January vs. early September to mid-March).</p><p>Description: — Plants perennial, cespitose, with high tiller production, with records up to 81 per plant, and variable vernation, folded or rolled, in the same individual. Culms 20.5–46.5 cm tall, decumbent; nodes 4–8, glabrous to pubescent. Leaf sheaths 5.5–12.5 cm long, usually pubescent, sometimes glabrous, closed for most of their length and open at the upper part; auricles absent; ligules 2–4 mm long (Fig. 3B), membranous, apex lacerate; blades 17–35 cm long, glaucous-green, linear, flat, with short dense pubescence. Panicles (Fig. 3E) 15.6–25 cm long, loose, elliptic-pyramidal, semi-contracted, with 28–105 spikelets; branches close to the main axis; lower branches 7.2–10.6 cm long and upper branches 2.4–5 cm long; pedicels 0.1–2.1 cm long. Spikelets (Fig. 3F) 1.7–3.6 × 0.4–1 cm, ovate-lanceolate, laterally compressed, with 6–10 florets; glumes glabrous, ovate-lanceolate, usually unequal, the upper one 1–3 mm longer than the lower one, persistent, longer than half the length of the lowest lemma, apex acute and keeled; lower glume 0.8–1.5 cm long, 5–8 nerved; upper glume 0.9–1.7 cm long, 7–9 nerved; lemma (Fig. 3G) of the basal floret lanceolate, 1.1–2.2 cm long, 7–9 nerved, usually glabrous, apex acute and keeled with sub-apical awn, straight, 0.5–3 mm long, palea (Fig. 3H) of the basal floret shorter than the length of the lemma, 0.7–1.3 cm long. Stamens 3. Caryopsis linear-lanceolate. Plants hexaploid, 2n=6x=42.</p><p>Phenology:— Flowering and fruiting occur from mid-October to the end of January.</p><p>Vernacular name:— “cebadilla de los médanos”, “sand dune brome”</p><p>Ecology and distribution:— Populations of the new species are distributed along 160 km of the coastline between the localities of Mar Chiquita (37°44’43.2” S, 57°25’10.7” W) and Quequén (38°33’44” S, 58°37’31.2”W). The species grows on alkaline soils (pH 8.2–8.6) with low organic matter content (0.7–2.4%), and sandy to loamy-sandy texture. It is commonly associated with the exotic species  Carpobrotus edulis (Linnaeus 1759: 1060) N. E. Brown (1926: 249) and the native species  Poa lanuginosa Poiret (1804: 91),  Panicum racemosum (Palisot de Beauvois 1812: 168) Sprengel (1824: 313),  Achyrocline saturejoides (Lamarck 1788: 747) Candolle (1838: 220),  Calystegia soldanella (Linnaeus 1753: 159) Roemer &amp; Schultes (1819: 184),  Margyricarpus pinnatus (Lamarck 1785: 567) Kuntze (1898: 77), and  Adesmia incana Vogel (1838: 76) . It grows in sympatry with other species of the genus:  B. catharticus var. catharticus,  B. auleticus, and  B. rigidus .</p><p>Etymology:— Dedicated to Botany Professor Sara Isabel Alonso, who encouraged us to investigate and describe this new species to science.</p><p>Additional material examined:—   Argentina.
