"Idioblastic" axial parenchyma cells are reported in Dinizia (Fabaceae) by Evans et al.
Fluorapatite (<1%) occurs as small grains (up to 250 [micro]m) are usually idioblastic and closely associated with Ti-clinohumite grains and clinochlore (Figures 7, 8a).
It is not only the grain size but also the grain size distribution that is important, with the effect that a large size range gives higher strength and better resistance to fragmentation and wear compared to a more equigranular or idioblastic rock (Lindqvist et al., 2007).
