2.3. 2Poa bactriana subsp. drobovii var. spicataSoreng & Cabi, stat. et nom. nov. ≡ Poa spicata Drobow, Flora Uzbekistanica 1: 538. 1941 (nom. illeg. hom., non L. 1767). Type. Uzbekistan • Tashkent district, Mynjullic demarcated area, upper reaches of Nurek Ata River, near the snowy spot, 17 Jul 1936, Korotkova et Titov 1476 (holotype: TAK {transferred to TASH} [TASH 000077]). Diagnosis. Like Poa bactriana subsp. drobovii but with bulbiferous spikelets. Distribution and ecology. Turkey, Uzbekistan. Habitat as in subsp. drobovii. Conservation status. None. Comments. The Type specimen of Poa spicata Drobow at TAK (now TASH) was confirmed as bulbiferous by Pazij (in Tzvelev 1976), by Olonova (pers. comm., 2024), and from the Type image and Olonova’s sketch (both seen by RJS). Although RJS believes it does represent subsp. drobovii, Tzvelev (1976, p. 434, p. 652 English translation) noted that subsp. drobovii was “ always nonviviparous ”. The bulbiferous form of P. bactriana subsp. drobovii seem to be rare. The morphology of the Type and of bulbiferous plants seen in Turkey agrees with that of normal flowered plants of subsp. drobovii. Kavousi et al. (2015) indicated P. bactriana is not bulbiferous in Iran. However, bulbiferous plants are generally difficult to separate from bulbiferous P. bulbosa and P. sinaica (noted for Iran) or P. iconia (not then recognized in Iran). We tentatively identify one bulbiferous specimen as P. bactriana subsp. drobovii var. spicata from Turkey, but it may represent reticulation with P. sinaica or P. bulbosa. Representative specimens.
