Single view of a 3-D sketch of the reconstructed dendrite morphology. Other views are shown in Supplementary Fig. S5. One (001)^* ribbon and four <10–1 > ribbons are shown. Arrows indicate growth directions of the different branch types. The crystallographic elongation directions of branches are color coded according to the key in the upper right. For clarity, the spacing between branches in the model is exaggerated. The level of detail in the sketch increases from left to right, but this does not imply spatial or temporal variation of dendrite morphology. Relative curvatures are representative of the real dendrites. Due to their weak curvature, all <12–1 > and {021}^* branches and short <10–1 > branches are drawn as straight.
