The specimens collected of this very polymorphous species, are distinguished by 

 having the stems about 20 cm. high, and, as the whole plant for the rest, completely 

 glabrous. The lower leaves are about 3 cm. long, and 1 mm. broad, i. e. of the same 

 breadth as the stem, linear, more or less recurved, equally broad throughout their length, 

 tapering and subobtuse at the summit, never raucronate. The lower leaves are of the 

 same length as the internodes, the upper ones gradually shorter, subulate, V^ — Vs of 

 the length of the internodes. The flower cluster rather few-flowered, the bracts and 

 bractlets minute, only few mm. long, membranous, with a more or less distinct midrib 

 projected into a greenish or brownish point. The calyx is about 3 mm. long, campanu- 

 late, with 5 distinct nerves, of a brownish green colour, its teeth triangular, acute, finely 

 and shortly cihate. The petals are slightly lilac, 6 mm. long. The specimens are, more- 

 over, characteristic in having the stems, especially in their lower parts, slightly genicu- 

 late in the nodes, and are here, at any rate when dried, very fragile, and easily broken. 



Scattered on the Abakan Steppe about the Lower Abakan, especially on the dry, 

 hot Devonian sandstone declivities, where I have collected them with flower-buds and 

 young flowers at the end of June. 



Distribution: South-eastern Russia (the government of Orenburg), southern Siberia, 

 eastwards to about the government of Yakutsk, northern Mongolia.

The specimens collected of this widely distributed and polymorphous species, are 

 distinguished by having the stems 20 — 30 cm. high, erect, or sometimes slightly 

 curved and ascending at the base, densely hirsute. The leaves are linear, 2 — 4 cm. long, 

 the broadest towards 3 mm. broad, 1-nerved, or rarely with 2 faint lateral nerves, 

 gradually acuminate towards the apex, horizontally spreading, or more or less 

 distinctly bent upwards, rough, especially underneath and along the margin 1- to few- 

 flowered; the calyx-scales are bent upwards, the outer ones about % shorter than the 

 calyx itself, consisting in the lowest part of a short, broad lamina, while their upper 

 two thirds are very narrow and subulate, the inner scales are comparatively broader, 

 and with shorter points, which are only about half the total length of the scale itself; 

 the inner scales are also shorter than the outer ones, Vs to Vs of the length of the calyx 

 itself. The scales are glabrous, or only very slightly scabrous. The calyx is 15 — 17 mm. 

 long, nearly glabrous, or only shghtly scabrous, very distinctly striped, its upper % — %
