The tallest species and the only one which grows well in dry places is Black Alder (561)—Alnus glutinbsa — of Europe, with gummy twigs, sometimes reaching the height of 70 feet. The figures given illus- trate' the great variety of foliage in the forms of this species. [Seeds; twig cuttings; suckers.] C6rylus. The Hazelndts and Filberts are shrubby plants with rounded hard-shelled nuts inclosed more or less in greeri leaf-like bracts. ^ig. 556. - Shrubby Birch. The leaves are alternate, simple, straight-veined with notched edges. The three common species can be best separated by means of the difference in the bracts which surround the nuts : in the Beaked Hazelnut (562) — Corylus rostr^ta, — 2 to 6 feet high, the bracts are not very leaf-like and project beyond the nut into a beak ; in the eastern Hazelnut () •— Corylus americana, — 3 to 8 feet high, these bracts form a fringe-like border generally hiding the nut; the Europeax Filbert (564) — Cory- lus Avellina — grows much taller, to 15 feet, and never has the bracts fully hiding the nut. , . , Of this last species, Fig. 557. — Seaside Alder. , . , ,_ -u i^.- which has been culti- vated for centuries, there are many named varieties: atirea, yellow leaves; laciniS,ta, deeply cut leaves; p^ndula, weeping; etc. The other.
