The crown is spreading and roundish. The root system is sturdy and very expanded but not very deep. The stem is straight and often squat. In the younger shoots the bark is smooth, brilliant brown-red, which tends to become grey as the season progresses. On the younger shoots are visible typical white and roundish lenticels.
Buds are smooth, short and squat with a dark-reddish color.
Leaves are apparently distich for the pedicel torsion, which is long between 1,5 and 2,5 cm. The veining is very evident. The vegetative cycle lasts 140-185 days. In general the male flowering precedes that of female flowers. The male flowers are grouped in the unisexual catkins located in the lower part of the shoot or, in the distal part of the shoot, in the bisexual catkins.
