. Comparative anatomy of the vegetative organs of the phanerogams and ferns. Plant anatomy; Phanerogams; Ferns. EPIDERMIS. 85 aggregated wax-covering, since it consists of an aggregation of very delicate rods or granules, which cover the cuticle not with a simple layer, but with several irregular layers. Examples of the aggregated rods are found on the white Eucalypti (E. globulus, pul- verulenta), Acacias (A, Hiigelii, cultriformis), Lonicera implexa Ait., Andromeda dealbata; Secale cereale, Elymus arenarius, Encephalartos horridus; examples of aggregated granules are found on Kleinia ficoide

EPIDERMIS. 85 aggregated wax-covering, since it consists of an aggregation of very delicate rods or granules, which cover the cuticle not with a simple layer, but with several irregular layers. Examples of the aggregated rods are found on the white Eucalypti (E. globulus, pul- verulenta), Acacias (A, Hiigelii, cultriformis), Lonicera implexa Ait., Andromeda dealbata; Secale cereale, Elymus arenarius, Encephalartos horridus; examples of aggregated granules are found on Kleinia ficoides, Ricinus communis, under surface of the leaf of Abies pectinata and its allies. Intermediate forms between the third and fourth type are sometimes found, e. g. leaves of Agave Americana. The wax-coverings usually cover the whole epidermal surface evenly, or with the differences of form described above for the epidermal cells of differing contour. The granular and aggregated coverings also overlie the guard-cells of the stomata up to the entry of the slit. The stratified coverings, where observed, leave the stomata free, in so far as they belong to parts already unfolded, or at least they become so thin as to be unrecognisable over the guard-cells. On the other hand the wax-layer of the young not yet unfolded leaf of the Carnauba palm completely covers the stomata also:.
