Thus, in surface-view, they exhibit two inner triangular cells, touching one another along one side, and these are surrounded by four other symmetrically arranged cells; two further cells adjoin these six cells internally. The lower side of the lid is differentiated as a slippery surface, and so are the folds of the collar. Three regions may be distinguished on the inner surface of the pitcher. The portion lying below the collar contains numerous glands (Fig. 69), which scarcely project above the surface of the wall of the pitcher, and are delimited towards the surrounding tissue by a suberized membrane. The glands of this zone are roughly flask-shaped, and consist of a large ventral part, formed by irregularly polygonal cells, and of a fairly broad Fio 60. cuad ct/--, neck-portion, composed of a layer of palisade-like Af, w c-bL cells, elongated at right angles to the surface of the pitcher. On the two lateral, brighUy-coloured projections, which penetrate like cushions into the interior of the pitcher, specially large glands are found, as well as numerous water-pores, which, according to Goebel, are peculiar, inasmuch as the subjacent parenchyma-cell, which is rich in contents, protrudes through the widely open pore. The lowest portion of the inner wall of the pitcher consists of epidermal cells with undulated boundaries, and without glands.
