Poa densa var. vivipara Tzvelev, Novosti Sist. Vyssh. Rast.

3.Poa densa var. viviparaTzvelev, Novosti Sist. Vyssh. Rast. 11: 40. 1974. Type. Nakhchivan Autonomous Republic. Type specimen. Prov. Nachiczevan, distr. Schachbuz, praticolum in regione montana altior 2–3 km ad occidentem vs. a pag. Biczenach; 23 Jun 1957, S. Čzerepanov et N. Tzvelev 361. (holotype: LE {n. v.}). Comments. We have never seen a bulbiferous specimen of Poa densa in herbaria or in the field (Cabi et al. 2016). Tzvelev (1974, 1976) placed the species in P. subsect. Bulbosae. Tzvelev (1976, p. 451, English translation, p. 683) noted that “ The viviparous variety is found very rarely and possibly originates from hybridization of P. densa × bulbosa s. l. ”, as also noted by Tzvelev (1974). This bulbiferous variety might be P. iconia var. iconia, a name Tzvelev was unaware of, or a form of another bulbous taxon.
