Aldir

Alder is the common name of a genus of flowering plants (Alnus) of the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs throughout the north temperate zone with a few extending into Central America and the Andes. A native tree, alnus glutinosa, the frequency of its pollen grains in peat deposits shows it was more plentiful in Britain in postglacial times. It shares with Leguminous plants the ability to absorb nitrogen in root-nodules which may be as large as a cricket-ball. The name derives from the Old English alor, and is found in place names - Aldershot (Alreshete, or alder copse) and Alresford. The wood has been used for water pipes, pumps and piling beneath bridges and houses. It burns slowly and provides one charcoal for making gunpowder. The catkins, twigs and bark give a black dye which Gerard (1) describes as a poor man's dye. Alder has also been used medicinally, Culpeper (2) recommending the leaves for 'bare feet galled with travelling' and for attracting fleas in a bedchamber so they could be 'suitably cast out'. Some regard the bark as astringent, a decoction a useful gargle for sore throats, and the glutinous leaves used to soothe inflammations.
Aspe

The aspens (Salicaceae) are native to cold regions with cool summers in the north of the Northern Hemisphere. It forms woods and produces thickets from shoots from the roots away from the parent even after the tree has been felled. The restless leaves rustle in the slightest breeze giving rise to such local names as Old Wives' Tongues and Woman's Tongue. Chaucer said of Cressida 'Right as an aspes leaf she gan to quake when she him felte hire in his armes fold' (3). The perpetual shaking of the leaves (populus tremula) has led to the invention of legends. In the Western Isles it was said to be cursed because it held up its head when the other trees bowed down during Christ's procession to Calvary. Because the cross was made from its wood crofters and fishermen avoided using it. In Wales it was thought the leaves could never rest because Christ was crucified upon a cross of Aspen wood. However, Grigson (4) wryly suggests that 'if the timber had been tougher, harder, more durable and more valuable, perhaps the legends would have been different'. He also reproduces a woodcut from Bock's (5) herbal of 1546.
