Type:— KAZAKHSTAN. Altai Talac , 11 June 1909, Minkwitz 1365 (holotype LE!) .

Description:—Bulb ovoid, 1.0–1.5(2.0) cm thick; tunic blackish-brown, sub-coriaceous, the inner surface densely covered with woolly hairs at the apex; stem 7–15 cm long, often red-tinged, the stem and peduncle densely pubescent; leaves 2, more or less approximate, commonly spreading, glabrous, smooth, linear, significantly exceeding the flower; lower leaf broader, 6–12 mm broad; flowers 1(2), opens to a wide creamy-white star with a large yellow blotch (rarely yellow without blotch); perigone segments 15–25 mm long, acuminate; outer segments lanceolate, dingy violet outside, glabrous, two-thirds as broad as the inner; inner segments oblong, gradually tapering into a claw, more or less ciliate at base; filaments yellow, thread-like, dilated and bearded at base, half the length of perigone; anthers linearoblong, yellow, 4–5 mm long, with a very short cusp; ovary pale green, about half the length of the stamens, with a long style and cream-coloured overlapping stigma; capsule pale beige with darker angles, rounded, up to 3.5×2.0 cm, with a short beak.

General distribution:—Tian-Shan, Pamir-Alay ( Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan).

Distribution in Uzbekistan:—I-1 Western Tian-Shan district (I-1-a Ugam-Pskem region; I-1-b Western Chatkal region; I-1-d Kurama region), I-3 Fergana-Alay district (I-3-b Eastern Alay region), I-5 Kuhistan district (I-1-a North Turkestan region).

Phenology:—Flowering: April–July; fruiting: July–August.

Ecology:—Fine earth, gravelly and stony slopes, in upper mountain zone, 2500–3500 m a.s.l.

Etymology:—Species epithet “ dasystemonoides ” means “similar to T. dasystemon ” (hairy stamen).

Note:— Van Raamsdonk et al. (1997) and Christenhusz et al. (2013) consider the species as synonym to T. dasystemon . According to Zonneveld (2009), these two species have different amount of nuclear DNA, 57.7 pg for T. dasystemoniodes and 51.5 pg for T. dasystemon . Morphologically, these species differ well from each other with bulb tunics ( Vvedensky 1935, Hall 1940, Botschantzeva 1962). Tulipa dasystemonoides sometimes has two flowers per stem, while T. dasystemon always has a single flower ( Vvedensky 1935, Hall 1940, Botschantzeva 1962). There is a similarity between Т. dasystemon and T. dasystemonoides , but T. dasystemonoides possesses densely wooly tunic and usually creamy-white flower ( Everett et al. 2013). They also show differences in bulb characteristics.
