Altogether, ENTS has confirmed four trees to heights of 51 m (167 ft) or more by climb and tape drop. In the Northeast, the tallest accurately measured tree is 44 m (144 ft). This tree, named the Seneca hemlock, grows in Cook Forest State Park, PA. Above 43°N latitude, the maximum height of the species is less, under 39 m (128 ft).

The bark of Sambucus is often used as “a cathartic, laxative, and diuretic”. [7] The preparation of the bark involves aging for at least a year so that the cyanide has time to degrade. Sambucus and other western species of elderberry need more time than other elderberry species as they have larger amounts of cyanide.
The Canadian flora is depauperate because of the near total glaciation event in the Pleistocene. Due to the vast area of Canada, a tree that is common in one area may be completely absent in another. In particular, many warm-temperate trees can only be grown on the mild Pacific coast (where gardens may contain additional species not listed here).
The dark horizontal lines on silver birch bark are the lenticels. [1]A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of gymnosperms and dicotyledonous flowering plants. [2]
The genus name comes from the Greek word sambuce, an ancient wind instrument, in reference to the removal of pith from the twigs of this and other species to make whistles. [ 14 ] [ 15 ] The boiled inner bark of the elderberry was used by the Iroquois of North America as a pain reliever in toothaches , being applied to the side of the cheek ...
The genus Quercus contains about 500 known species, plus about 180 hybrids between them. [1] The genus, as is the case with many large genera, is divided into subgenera and sections. Traditionally, the genus Quercus was divided into the two subgenera Cyclobalanopsis, the ring-cupped oaks, and Quercus, which included all the other sections.
Cercis species are used as food plants by the larvae of some Lepidoptera species including mouse moth and Automeris io (both recorded on eastern redbud). The bark of C. chinensis has been used in Chinese medicine as an antiseptic. [7] Cercis fossils have been found that date to the Eocene. [8] [9]
