As stated, H. sambuci occurs in North Europe mostly on Sambucus nigra, but there is a much bigger spectrum of substrates in warmer regions in southern areas.The variability of micromorphology increases in the tropics, but the macromorphological characteristics however always stay the same: the basidiocarp with chalky white color and often growing as aerophyte on dead branches of trees and ...
Tibouchina species are subshrubs, shrubs or small trees. Their leaves are opposite, usually with petioles, and often covered with scales. The inflorescence is a panicle or some modification of a panicle with reduced branching. The individual flowers have five free petals, purple or lilac in color; the color does not change as the flowers age.
The lichen is a generalist epiphyte of deciduous trees and is acidophilic. Its abundance appears to have increased generally since the 1970s, possibly in responses to changes in air pollution levels [2]
Ceiba speciosa, the floss silk tree (formerly Chorisia speciosa), is a species of deciduous tree that is native to the tropical and subtropical forests of South America.It has several local common names, such as palo borracho (in Spanish literally "drunken stick"), or árbol del puente, samu'ũ (in Guarani), or paineira (in Brazilian Portuguese).
Brugmansia sanguinea. Brugmansia are large shrubs or small trees, with semi-woody, often many-branched trunks. They can reach heights of 3–11 m (10–36 ft). The leaves are alternately arranged along the stems, generally large, 10–30 cm (4–12 in) long and 4–18 cm (2–7 in) across, with an entire or coarsely toothed margin, and are often covered with fine hairs.
Tree paint or whitewash protects against this. [2] Some tree paints, depending on ingredients, also protect against insects and rodents. For example, neem oil has been used by Indian farmers for thousands of years as a natural insect repellent and insecticide. A diluted neem oil spray repels insects and smothers those that come into contact ...
While the perceived risk of death by falling trees (a part of the "tree risk" complex) is influenced by media and often hyped (the objective risk has been reported to be close to 1 : 10.000.000, almost as low as death by lightning), [6] singular events have encouraged a "proactive" stance so that even lightly damaged trees are likely to be removed in urban and public traffic surroundings.

Several trees normally have marcescent leaves such as oak (Quercus), [5] beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows . [6] All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. [ 7 ]
