Abstract: 2.2. 2Poa bactriana subsp. glabriflora var. tzvelevianaSoreng var. nov. Type. Iran • Kerman, ca. 60 km SE of Kerman along road to Bam., rocky slopes, limey sedimentary rocks, 8800 ft [2682 m], 11 May 1955, H. S. Gentry 14812 (holotype: US [US 15910016]). Diagnosis. Like Poa bactriana subsp. glabriflora var. glabriflora, but bulbiferous. Distribution and ecology. India, Iran, Tajikistan, and evidently more widely distributed, as Tzvelev (1976, p. 435 in key, p. 652 in English version) noted subsp. glabriflora as “ often viviparous ”. Conservation status. None. Comments. As the fully bulbiferous Type specimen is nearly identical to the fully normal flowered form, Gentry 14810, from the same locality, it is evident for taxonomic symmetry that a bulbiferous form needed to be formally recognized. The name honors Nikolai Nikolaievich Tzvelev who noted the bulbiferous form of subsp. glabriflora was frequent. The identification of bulbiferous specimen from Ağri (Emlik VANF 11191) as Poa bulbosa var. vivipara or P. bactriana var. tzveleviana is uncertain. Representative specimens. Turkey. Ağri (Emlik VANF 11191 [20238801-203951. jpg, det. uncertain]. India. (Mt. Shankacharya, Rodin 8227 US). Iran. (Type). Tajikistan. (30 Jul 1892, Komarov, p. p. right-hand bulbiferous specimen [LE 01265567, image!]).
