WebIn this view, the "zosterophylls" comprise a paraphyletic group, ranging from forms like Hicklingia, which had bare stems, to forms like Sawdonia and Nothia, whose stems are covered with unvascularized spines or enations. The genus Renalia illustrates the problems in classifying early land plants.
WebNemophila aphylla, the smallflower baby blue eyes, is an annual flowering plant in the family Boraginaceae.
