Trees have paper-like bark. Snapped twigs have wintergreen aroma. Bark and twig tea used for lung problems, sore muscles, joint pain, skin fungus, cracked heels, bladder and urinary issues, stomach aches, laxative, diuretic, colds, fever, rheumatism, diarrhea, tumors, cancer, anti-viral, anti-inflammatory, skin cancer. Birch tea has been historically used in enemas. Worm-like flowers (catkins) also edible.

Betulaceae

 

a family of monoecious, dicotyledonous plants.

Betulaceae are trees or shrubs with alternate leaves and early falling stipules. The flowers are small, plain, unisexual, anemophilous, and gathered into compound, catkin-like inflorescences consisting of extremely vestigial dichasia (two or three flowered). The staminal (male) catkins are pendulous, long, and cylindrical; the pistillate (female) ones are more or less upright, shorter than the staminal ones, and cylindrical or oval. The ovary is on top. The fruit is nutlike, winged, or wingless. There are two genera of Betulaceae: Betula (birch) and Alnus (alder). The number of species is very approximate (because of highly developed hybridization of the birch) but is close to 200. Betulaceae are distributed chiefly in the nontropical regions of the northern hemisphere, but they are also found in southern Asia and in America as far south as Chile and Argentina. Both the birch and the alder are important timber-forming species. Sometimes the hazels are included in the Betulaceae family as a special subfamily.

Here, in the Okanagan Highlands, numerous groups of animals and plants make their first appearances in the fossil record; for example, genera such as hazel (Corylus) and hornbeam (Carpinus) in the birch family (Betulaceae); the oldest known service-berry (Amelanchier), snow-wreath (Neviusia), and cherry (Prunus) in the rose family (Rosaceae); winter-hazel (Corylopsis) and witch-alder (Fothergilla) in the witchhazel family (Hamamelidaceae); and beech (Fagus) in the beech family (Fagaceae) (e.g.

Although compensatory growth is known to occur in many plant species, including conifers (Edenius et al., 1993), it is more obvious and easier to detect in hardwood shrubs and trees such as the Salicaceae (poplars and willows), Ulmaceae (elms), and Betulaceae (birches, alders, and hazels) - all of which we use for demonstration purposes in our class.
