30, oil shorl pinlicols. 0.5— U.H cm. long. I he l)r;icls are linear lo lanceolate. 3—5 

 mm. long, with acute apices. The calyx is ahoiit 1 nnn. long, its upper lliird split into 

 triangular lobes, subacute or subobtuse at the top. The tube is generally of a yellow colour. 

 mostly projecting 1 nnn.. larely more, beyond the calyx. The limb is from ti— 7 mm. 

 in diameter, of a pale violet, gradually darker tow-ards the throat, or through evei-y 

 shade of colour to a nearly shining white. Khvlow (#.i. A.it. 111. p. 807 and p. 812) 

 records the whole plant as completely glabrous, not mealy. In the specimens at hand 1 

 have found, however, the pedicels and the calyx always to be markedly mealy, also tlie 

 bi'acts and even the upper part of the stem generally more or less distinctly mealy, of a 

 whitish hue. The young scapes, as yet only one inch high, are completely white-mealy. 

 On the otlier hand, the leaves seemed always to be glabrous, at any rate when full-grown. 



Occurring on the Abakan Steppe, near I'st Kamuishto. in grass-grown, clayey, 

 mostly saline soil, accompanj'ing Ranunculus planlaginifolius, Lepidium cordalum, Lepi- 

 dium crussifolium. Pluntago mnriliinu sul)s|)cc. n7z«/o. and other halophilous plants. In 

 full flower in the second half of June. 



Distribution: South-eastern Russia. Caucasia, Turkestan, the Thian-Shan. southern 

 Siberia, northern Mongolia.

The specimens collected are distinguished by comparatively long petioles, about 

 tAvice tlie length of the blade, the margin of which is entire. The calyx is 5—8 mm. long, 

 its upper third or fourth cleft into rather l)lnnt lobes, rather densely ciliate. The 

 length of the pedicels is much varying, 0,5—3 cm., the number of the flowers 1—3, 

 mostly 2. The tube is yellowish green, 10—11 mm. long, from one third to twice as long 

 as the calyx. The limb is 12—14 mm. in diameter. In full flower about the middle of 

 June. 



The plant is of rather common occurrence on the Abakan Steppe, near Askys. 

 where growing in moist, grass-grown cavities on the steppe, near the river, associated with 

 plants such as Carex capillaris. Orchis spec. div.. Cijpripediluni njacranthum. Herniiniuni 

 Monorchis. Trollius asialicus, Comarnm palustre, etc. 



Distribution: The main species is distributed over the arctic regions of Europe, .\sia 

 and America, as well as on Greenland, and the mountain regions of central Asia. The 

 variety brevicalyx occurs only in central Asia, from the Hindoo-Koosh to the north-western 

 Himalayas, the Altai and Sayansk districts, Baikal, Trans Baikal, to China (Kan-su).
