All the Labiatae (comp. Meyen, Unger, Hanstein, Rauter, Martinet / c.) have besides various other forms of hairs, short glandular hairs, consisting of a pedicel-cell lying in the epidermis, a short stalk-cell borne by this, and seated on the latter a glandular head, covered by a great secretory bladder. The head is in the simplest cases a spherical cell; c.^-. Pogostemon Patschouli, Fig. 38: in most cases a spherical group of four cells (Lamium album, Rauter, /. c.; Plectranthus fruticosus. Fig. 21, A, p. 59); also, it not uncommonly grows on, with further division, to a multicellular peltate scale, as in the case of the large, about 12-celled, depressed glands of many species.
