Bicollateral vascular bundles consist of two patches of phloem (outer and inner), two strips of cambium (outer and inner) and one patch of xylem at the center. The arrangement of xylem and phloem bundles jointly in the same radius is referred to as collateral bundles. Bicollateral vascular bundles are characteristic of Solanaceae. In plicate aestivation (aestivatio plicata) the whole organ (calx or corolla) is not divided into parts but folded and sometimes also twisted lengthwise; So, the correct answer is 'Solanaceae' which is option 2.
