description: 2. Sect. Kolpakowskianae Raamsd. ex Zonn. & Veldkamp in Pl. Syst. Evol. 298(1): 90. (2012).
Type:— T. kolpakowskiana Regel in Trudy Imp. S.-Peterburgsk. Bot. Sada 5: 266. (1877).
Ten species of the section distributed in various geographical and ecological niches which led to variability in morphology. Mainly, species of the section present strongly prolonged bulb tunic, slender stem, yellow tepals, narrow and glaucous leaves. Key for identification of species is given below.
Identification key for Tulipa sect. Kolpakowskianae in Uzbekistan
1. Small plants up to 20 cm tall; leaves approximate, exceeding the flower; ovary with long style .....................................................2
– Relatively tall plants (up to 45 cm); leaves more or less widely spaced; ovary with sessile or subsessile stigma ............................3
2. Perigone segments yellowish, without basal blotch, outer ones greenish on the back, the edges of the upper half often notched, two-thirds as broad as and slightly longer than the inner segments; tunic brown or grayish, papery...........................7. T. hissarica
– Perigone segments white with yellow basal blotch, outer ones violet tinged on the back, up to half as long as the inner segments; bulb tunic dark brown (almost black), coriaceous.................................................................................................... 8. T. korshinskyi
3. Bulb tunic fibrous, splitting, black to tawny, prolonged to soil surface, inside densely covered with curly woolly hairs; stamens one-third to two-fifths the length of perigone; filaments black to purple ..........................................................................................4
– Bulb tunic not fibrous and splitting, black, dark brown, not prolonged (T. scharipovii) or slightly prolonged (if prolonged up to soil surface, they are lined with woolly hairs at the top and glabrous below); stamens two or three times shorter than the perigone, filaments yellow .................................................................................................................................................................................5
4. Upper leaves exceeding or at least reaching the flower; aboveground part of the plant one-half to two-thirds as long as the underground part; perigone segments with a dark violet blotch on both faces .........................................................2. T. borszczowii
– Upper leaves do not exceed the flower; aboveground part as long as or slightly longer than the underground part; perigone segments commonly with a dark basal blotch on the inner face, rarely on both faces ..........................................1. T. lehmanniana
5. Upper part of stem and peduncle pubescent; leaves never lying on the soil surface ...................................................4. T. ferganica
– Upper part of stem and peduncle glabrous; leaves approximate (sometimes almost verticillate) and usually lying on the soil surface.................................................................................................................................................................................................6
6. Bulb tunic not prolonged, coriaceous; plants of relatively slender habit; leaves narrow lanceolate, do not exceed the flower; flower pendulous in the bud, perigone segments yellow, without blotch, elliptic, at the apex obtuse or sinuate, after anthesis turn brownish in the upper part; filaments yellow, narrow triangular (dilated at the base); ovary not bottle-like; grows in piedmonts on slightly saline soils ................................................................................................................................................................. 5. T. scharipovii
– Bulb tunic usually prolonged, thin coriaceous; plants of relatively stocky habit (sometimes with almost sessile flowers); leaves usually exceeding or at least reaching the flower; perigone segments red, yellow, orange, pink or motley, acute or with a small tip at apex, sometimes obtuse; grows in foothills and mountains on gravelly and stony slopes.............................................................7
7. Bulb tunic tough, almost scaly, dark in colour; leaves approximate to more or less widely spaced; perigone segments usually red with a small black marginless basal blotch, sometimes yellow-red or yellow or pink colour; filaments commonly black in the lower part and purple in the upper part, sometimes entirely black or purple ...............................................................................................8
– Bulb tunic thin coriaceous, darkish brown in colour; leaves always almost verticillate; perigone segments yellow, reddish-orange or light red ..........................................................................................................................................................................................9
