ovate-lanceolate, frequently broadest in the lower half; the base is rounded or at times 

 nearly cordate, not narrowed, the apex acute or acuminate. They are usually destitute of 

 petioles, completely sessile, and distinguished by being comparatively more markedly 

 black-punctate than is common in the Scandinavian specimens with which I have com- 

 pared them. The leaves are to 3,5 cm. broad, and to 8 cm. long; the margin is plane or 

 rarely slightly revolute, entire or slightly and irregularly crenulate. There seemed to occur 

 intermediates between this variety and the following one.

This variety, being distinguished by its more narrowly lanceolate leaves, generally 

 only 2 opposite ones, I have gathered on the islets in the Lower Abakan, and in the Urjan- 

 kai counti-y, on the Sisti-kem. The shape and size of the leaves are somewhat varying. The 

 lower ones are narrowest, very narrowly lanceolate, only from 5 — 6 mm. broad, and 5 or 

 7 times as long, broadest at the base, tapering towards the apex. The upper ones gradually 

 become broader, the uppermost broadly lanceolate, and, moreover, frequently also being 

 verticillate in 3's. All the leaves are sessile; their margin is slightly undulate and revo- 

 lute. The lower stem-leaves ai'e gradually reduced downwards to scales. The specimens 

 collected are mostly more hirsute than the preceding one, especially so in the upper parts of 

 the plant, and on the under side of the leaves. In the structure of the flowers both varieties 

 seemed to agree, but the latter always seemed to have 3 rather distinct nerves on the sepals, 

 the former, according to my material, wanting distinct nerves. The universality of this 

 character, however, cannot be definitely settled on account of the scarcity of my material. 

 The pedicels in both varieties, are, during the flowering season, of about double the length 

 of the calyces. The variety davurica seemed, for the rest, not to be strictly distinguished 

 from the variety lypica, but connected with intermediates. 



Distribution: Europe, except the most northern and southern parts, Caucasia, 

 Asia Minor, south-western Asia and Turkestan, Siberia, in the government of Tobolsk, 

 northwards to 62° 10' north lat., and in the government of Yeniseisk to 60° 10' north lat., 

 eastern Asia, India, North Africa. The variety davurica especially occurs in the eastern 

 geographical area of the species, from south-eastern Europe, through the Altai region, the 

 Sayansk district, Baikal, Manchooria, to China and Japan.

The specimens collected are nearly completely glabrous, wanting the rusty-red, 

 curly hairs generally to be found in Norwegian specimens. The raceme is comparative-
