Solitary, pale to bright blue-green trichomes, with fine or coarse granulation and sometimes scatterings of larger granules; short, straight, sometimes curving slightly. Cells short barrel-shaped to cylindrical-hexagonal with rounded ends, more or less constricted at the middle, apical cells with obtuse-conical to acute-pointed ends. Cell width 5-6 µm, 0.75-1.5 x as long as wide, 5-9 µm long. Cells mostly isodiametric, longer before division, shorter after division. Strongly constricted at cross-walls, no sheath.
