In the Altaian, in alpine grass-fields, among stones and gravel. In full flower at the 

 end of July. 



Distribution: Northern Russia, arctic Siberia, eastwards right up to Behring's 

 Ocean, the Thian-Shan, the Altai, the Sayansk district, the Himalayas.

On stony declivities and meadows in the Altaian, about the tree limit; in flower in 

 the last days of July. 



Distribution: Eastern Altai and Sayansk mountains, northern Mongolia.

Not uncommon on open, wooded mountain slopes, and the like, in the subalpine 

 tracts of the Sayansk mountains: near Kushabar, in the Amyl valley, at Ust Algiac, Ust 

 Sisti-kem, and in the Altaian. Collected flowering and partly with capsules in July and 

 the first half of August. 



Besides the typical species, I have collected, in subalpine wooded tracts in the 

 Altaian, about the Upper Sisti-kem, a series of specimens differing in various characters 

 from the typical plant. I separate the latter under the name of 



subspec. subalpina nov. subspec. [Tab. XIII, Fig. 1].

It is chiefly by the rather long, unequal calyx-lobes, distinctly acuminate or even 

 mucronate at the top, by the long, sometimes foliaceous bracts, by comparatively longer 

 pedicels, and the 3 lobes of the lower lip being slightly emarginate that this subspecies 

 differs from the typical plant. The stem is fvu'nished at the base with large, withering, mem- 

 branous, brown leaf-sheaths or scales, to 2— 3 cm. long. The petioles of the basal leaves are 

 about Vi as long as the blade, the upper leaves more shortly petioled, the uppermost ones 

 sessile. The leaves are also gradually decreasing in size up the stem, passing by degrees 

 into the bracts, of which the lower ones, at any rate, are large and foliaceously develop- 

 ed. The segments of the leaves are lanceolate, generally somewhat broader and closer
