However, we wonder if the former might have arisen via hybridisation with other Poa species in North America like the annual P. bigelovii Vasey &amp; Scribn. (originally included in Poa sect. Diversipoa (Chrtek and Jirásek 1962) along with other North American annuals, all Hph types), which has similar lemma pubescence and infrequent reduction to 1 or 2 stamens where it approaches the geographic range of P. chapmaniana or even older hybridisations in Latin America (Soreng 2007).</p><p>What is really going on will hopefully become apparent once more nuclear DNA of more species of Poa become available. We wonder if species with Rr genotypes were once more diverse and widespread, but continental American species nrDNA signals were mostly swamped out by concerted evolution and their chloroplasts displaced by in hybridisation with more numerous northern and southern Western Hemisphere species of Poa supersect . Homalopoa.</p><p>One stamen is rare in Poa, but P. tucumana Parodi, of the monotypic P. sect. Monandropoa (Parodi 1962), also has one anther per floret. The species is known from the Argentinian Provinces Tucuman and Catamarca (Giussani et al. 2012) and, here, it is tentatively placed in P. subg. Parodiochloa . A recent collection from the next province north (Prov. Salta; E slope of Sierra de Santa Victoria, 12 air km ESE of Abra Lizoite on new road to Santa Victoria, 4175 m elev., margins of a small alpine tarn, 22.26850 S, 65.11736 W, 29 Mar 2006, Peterson et al. 19606 US [voucher misplaced at US]), with its perennial habit, small stature and open panicles might belong to this species (RJS recall). This accession aligns within the Parodiochloa clade in both plastid and nrDNA trees. Poa tucumana is small, slender perennial species exhibiting open panicles, small, 2 - flowered spikelets, glumes 3 - nerved, floret callus with soft, short (to 2 mm long) hairs, callus with woolly hairs surrounding the lemma base, lemmas 5 - nerved, unawned, keel scaberulous, lower body with a few minute appressed hairs, anthers one per flower, similar in some respects to P. chapmaniana (Giussani et al. 2012) . Its slender unbranched stigmas, although vestigial, are reminiscent of the linear styles of P. flabellata .</p></div>	https://treatment.plazi.org/id/70E612A643EE5D43B120A019A60A9F86	Public Domain	No known copyright restrictions apply.

Herb. 48: 604, 4. 2003. (non- Poa trachyantha Hack., 1912 .).</p><p>Note.</p><p>The species is here renamed in honour of Dra. Ana María Molina, Argentine Botanist, Agrostologist.</p><p>According to Finot (Finot 2022, p. 966), this unusual annual species occurs in the coastal Loma vegetation of the Atacama Desert in northern Chile and southern Peru (24 ° 50 ' – 33 ° 39 ' S), has peculiar rough upper glume and lemma surface texture “ escabroso-hirsutas, coriaceous ” and tightly contracted panicles similar to Rostraria cristata (L.) Trin. and lemmas with short apical awns (1–2 mm), the lemma apex sometimes apically short lobed (see Illustration, in Finot 2022, p. 965, Lámina 357). These characteristics are reminiscent of the densely scabrous and coriaceous lemmas with stiff apical awns in Poa flabellata (Lam.) Raspail (the type species of Parodiochloa C. E. Hubb., also a synonym of Poa). Curiously both of these species have short, stiff apical awns on the lemmas (rare in Poa) and narrow, congested panicles (extreme in P. ana-molinae for Poa).</p><p>Plastid and nrDNA data place Poa ana-molinae in well supported and consistent clades named “ Parodiochloa ” (R plastid and r nrDNA clades; see Soreng et al. (2020) for clade coding), with formally named sections Poa sect. Parodiochloa (C. E. Hubb.) Soreng and P. sect. Tzvelevia (E. B. Alexeev) Soreng &amp; L. J. Gillespie. The Rr - clade hitherto was demonstrated to contain a series of perennial species with narrow, compact, contracted panicles, from widely distributed sub-Antarctic oceanic islands and Tierra del Fuego [ P. cookii (Hook. f) Hook. f, P. flabellata, P. kerguelensis (Hook. f.) Steud. (type of Tzvelevia ≡ Poa sect. Tzvelevia), P. ramosissima Hook. f.] and one annual species with open panicles from south-eastern United States, P. chapmaniana Scribn. (Gillespie et al. 2007; Refulio-Rodríguez et al. 2012; Persson and Rydin 2016; Soreng et al. 2022 b). Both of the annuals, P. ana-molinae and P. chapmaniana (type of P. sect. Diversipoa Chrtek &amp; V. Jirásek) have one stamen per flower, but later has a web on the callus and lemmas with well-developed soft pubescence on the keel and marginal nerves and shorter hairs on the surface and open, pyramidal, thin-branched panicles, while the other taxa in the Parodiochloa clade (including P. ana-molinae) lack callus hairs and lack much (at most, coarse and short) pubescence on their lemmas and have contracted panicles. The three sections are united here in a subgenus Parodiochloa . The two sections mentioned above were formerly placed in P. subg. Ochlopoa (Asch. &amp; Graben) Hyl. However, the monophylly of the Ochlopoa clade as originally resolved and constituted (Soreng and Gillespie 2007; Gillespie et al. 2008) no longer has support (Soreng et al. 2020) in nrDNA trees and we here restrict subg. Ochlopoa to encompass species included in P. sect. Micrantherae Stapf. (type P. annua L.), including P. cyrenaica A. Durand &amp; Barratte (formerly the sole species in the genus Libyella Pamp.).</p></div>	https://treatment.plazi.org/id/E5543EDB71D15FDAB144180000FC5F9E	Public Domain	No known copyright restrictions apply.
