For a representative list of studied materials, see Suppl. material 1.  Notes. Spikelets in this species usually have 2-3 flowers, but can have 3-7, a rare phenomenon observed more frequently in populations in NE Spain. The most distinctive characteristic of  Poa flaccidulais the sericeous or appressed-hairy indumentum of the intervein zone of both the lemma and palea. This species is sometimes confused with  P. annua, but, along with other differences, the latter is an annual, not a perennial.  Poa flaccidulacan also be confused with  P. trivialis, which, like  P. flaccidula, has a ligule that is longer than the width of the leaf blade and possesses hairs at the base of the lemma that are longer than its width; however, both the palea and the internerval surface of the lemma is glabrous in  P. trivialis.  P. flaccidula subsp. guadianensisF.M. Vazquez, Folia Bot. Extremad. 9: 66 (2016) has recently been described from Extremadura (SW Spain), but examination of the type material (HSS 65616; COF 62937 isotypus) reveals that this taxon is in no way attributable to  P. flaccidula. The most we can say, given the immaturity of the specimens, is that it may be of hybrid origin, with  P. bulbosapossibly one of the parents. 1849-06 San Cristobal Cerro de San Cristoval Serrania de Ronda 1 lectotype
