Cornaceæ. 133 



BucHENAU States, that the two uppermost pairs are 

 closely placed, resembling a whorl; all the specimens from 

 one Danish locality (Maglemose in Grib Skov) examined by 

 me showed the same, луЬНе plants from other Danish loca- 

 lities did not. On arctic material I never found it. 



The aerial part of the shoot attains a height of from 

 6 to 30 centimeters and is annual. The stem is quadrang- 

 ular and has two opposite grooves (fig. 12), which change 

 sides at each internode, the leaf pairs being placed at their 

 lower ends. The scale-leaves, with which the perpendicular 

 part of the shoot commences, support buds, the first pair 

 excepted; and some of the buds develop next year into 

 shoots with foliage leaves, growing upwards immediately, 

 and showing no inclination to become runners. These shoots 

 also commence with a number of red scale-leaves, after 

 which follow foliage-leaves. The same ramification takes 

 place the following year from the scale-leaf buds of these 

 shoots, and so on, thus forming a tufty growth. 



According to BucHENAU, it is always the buds ap- 

 pearing in the axis of the second pair of scale-leaves which 

 develop, so that all the shoots are placed at the same level. 

 This is however far from always being the case, often it is 

 from the uppermost pair of scale-leaves or the one next to 

 this, from which next year's shoot develops, and often only 

 one bud from a pair of scale-leaves develops, although the 

 second one can very well develop later during one of the 

 follo\Nang years. 



The buds which are to develop into shoots next year, 

 are in the autumn of a considerable size and the first two 

 pairs of leaves are brown and formed like bud-scales. The 

 whole shoot completely formed is inclosed in the winter- 

 bud, also the inflorescence and the first indications of the 

 buds to develop the 2nd year. 



The leaves of Cornus suecica fall in the autumn, while
