--><p>Stems of <i>Herzogiella</i> often have large, thin-walled epidermal cells and smaller, thick-walled, cortical cells in few rows. The axillary hairs have two basal cells and two apical cells; the sparse, papillose rhizoids emerge in the leaf axils or just below, or are often restricted to stem bases. The leaves are rigid, symmetric, concave, and sometimes distally secund at the stem and branch apices; there are sometimes 1–4 alar cells along the margins that are differentiated from the thick-walled, linear-fusiform laminal cells. The inflorescences are near the base of stems; the seta is often twisted; the capsule is usually striate when dry, with a wrinkled neck; the exostome teeth are bordered and internally trabeculate; and the endostome is papillose.</p>
