Diversity of roots and root systems in pauciennial dicots
Historically borned stereotype on allorhizy of pauciennial (annual-biennial) plants from Dicots can be valuable interference for objective representations (describing) of this extremely interesting flowering plant group diversity. Via more attentive and deep research of the morphology and anatomy of roots in their ontogenetic development dynamics we can observe (reveal) ncompleteness of our knowledge in this area and unsufficient level of terminology which could have negative influence on our published text-books content. Hackneyed examples that were presented in these text-books can illustrate far from the full picture of natural diversity of root morphology and anatomy with some valuable details of their development obviously underestimated or simply omitted. There is a collet amongst these details - more or less inflated transition zone between radicle and hypocotyl with its own anatomy and morphology features (cover from trichomes or rhyzoides), including lateral roots primordia which can be initiated inside even during embryogenesis.
