GROUP III. THE RED CEDAR AND ARBOR-VITAE How to tell them from other trees: The red cedar (juniper) and arbor-vitae may be told from other trees by their _leaves_, which remain on the tree and keep green throughout the entire year. These leaves differ from those of the other evergreens in being much shorter and of a distinctive shape as shown in Figs. 12 and 13. The trees themselves are much smaller than the other evergreens enumerated in this book. Altogether, there are thirty-five species of juniper recognized and four of arbor-vitae. The junipers are widely distributed over the northern hemisphere, from the Arctic region down to Mexico in the New World, and in northern Africa, China, and Japan in the Old World. The arbor-vitae is found in northeastern and northwestern America, China, and Japan. The species mentioned here are those commonly found in America. How to tell them from each other: The _twigs_ of the arbor-vitae are _flat and fan-like_ as in Fig. 13; the twigs of the red cedar are _needle-shaped or scale-like_ as in Fig. 12. The foliage of the arbor-vitae is of a lighter color than that of the red cedar, which is sombre green. The arbor-vitae will generally be found growing in moist locations, while the red cedar will grow in dry places as well. The arbor-vitae generally retains its lower branches in open places, while the branches of the red cedar start at some distance from the ground. RED CEDAR (_Juniperus virginiana_) |
