Abstract
The epidermal nuclei of the ovary inLinaria vulgaris andL. alpina, and the nuclei in leaves ofIncarvillea variabilis often contain crystalloid, tubular inclusions. The tubuli in bothLinaria species have an average diameter of 200 Å with a width of 70 Å in the clear and are arranged in a higly organized manner: Parallel tubuli form layers which build up a crystal lattice. There are three directions of tubuli in each inclusion: In each layer they are aligned in an angle of 60° to those of the next, so that the tubuli of the fourth layer are in the same direction as those of the first one. InIncarvillea the tubuli (each with an average diameter of 220 Å, and 70 Å width in the clear) also exhibit compact packing, but their arrangement is not so highly ordered as inLinaria.
