The margin of the leaves is sharply and coarsely serrate, with appressed. Fig. 106. Veronica pseudolongifolia nov. spec. Different types of leaves, with complete petioles, the two on the right hand side conduplicate ('/i). teeth; only rarely the margin may be slightly duplicate-serrate. There occur sometimes specimens in which the apex of the leaf is entire or nearly so. The leaves are com- monly opposite, or verticillate in 3's; more than 3 leaves in each node have not been found by me in any of the specimens collected. The middle stem-leaves are 1,5—2 cm. broad, and 7—10 cm. long when full-grown; of more rare occurrence are narrow-leaved specimens, the leaves of which are only about 1 cm. broad. There occur frequently spe- cimens with nearly rectangularly spreading leaves, distinctly conduplicate, so as to exhibit a form parallel to f. complicata, of the nearly allied species V. lonqifolia.
