The principal bud may produce leaves during the first 

 year, but I do not think it does so always, the first leaf is

A, A fragment of a plant from Præstefjæld; 16.7. 1884; Vs. The flower has been cut 

 off and placed by the side. The upper foliage-leaf subtends the principal bud of which 

 the growth begins with an elongated internode; I, basal part of the stalk of a foliage-leaf.

 the shoot (•'■'/a). C, Flower seen from above {^h). The perianth leaves are of unequal size;

 the rejuvenating shoot. Also other leaves than the uppermost 

 one may subtend shoots which are very similar to the principal 

 bud. — The slender, branched, adventitious roots arise from 

 the rhizome a short distance below each node.
