The broad oblong to obovate leaves are 10–20 centimetres (4–8 inches) long, rough above but velvety below, with coarse double-serrate margins, acuminate apices and oblique bases; the petioles are 6–12 millimetres (1 ⁄ 4 – 15 ⁄ 32 in) long. [5] The leaves are often tinged red on emergence, turning dark green by summer and a dull ...
Burl wood is very hard to work with hand tools or on a lathe, because its grain is twisted and interlocked, causing it to chip and shatter unpredictably. This "wild grain" makes burl wood extremely dense and resistant to splitting, which made it valued for bowls, mallets, mauls and "beetles" or "beadles" for hammering chisels and driving wooden ...
The bodies of Japanese Taiko drums are often cut from the wood of old elm trees, as the wood's resistance to splitting is highly desired for nailing the skins to them, and a set of three or more is often cut from the same tree. The elm's wood bends well and distorts easily.
Ulmus laevis Pall., variously known as the European white elm, [2] fluttering elm, spreading elm, stately elm and, in the United States, the Russian elm, is a large deciduous tree native to Europe, from France [3] northeast to southern Finland, east beyond the Urals into Kyrgyzstan and Kazakhstan, and southeast to Bulgaria and the Crimea; there are also disjunct populations in the Caucasus and ...
The wood of the rock elm is the hardest and heaviest of all elms, and where forest-grown remains comparatively free of knots and other defects. It is also very strong and takes a high polish, and consequently was once in great demand in America and Europe for a wide range of uses, notably boatbuilding, furniture, agricultural tools, and musical instruments.
The perfect hermaphrodite flowers appear before the leaves in early spring, produced in clusters of 10–20; they are 4 mm across on 10 mm long stems, and being wind-pollinated, are apetalous. The fruit is a winged samara 20 mm long and 15 mm broad, with a single, round, 6 mm seed in the centre, maturing in late spring.
The elm cultivar Ulmus 'Rubra' was reputedly cloned from a tree found by Vilmorin in a wood near Verrières-le-Buisson in the 1830s. [1] [2] It was listed in the 1869 Catalogue of Simon-Louis, Metz, France, as Ulmus campestris rubra, [3] and by Planchon in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis (1873) as Ulmus libero-rubra: 'Orme à liber rouge' [:elm with red inner ...
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not heavily processed, and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as either hardwood or ...
