Spearfish

--- CONTENT ---
The spearling (Sorbus domestica) – regionally also called spearling, sperber tree, spear tree, spree gel – is a plant species from the genus of the flourberries (Sorbus, boar ashes) within the family of roses (Rosaceae). It is considered a wild fruit tree and as wild wood one of the rarest tree species in Germany; In 1993, the Speierling was voted Tree of the Year here because of its declining stock.

Not to be confused is the fruit with the spilling, which in Austria is also referred to with the similar sounding name Spenling.

Description

Appearance
The spearling grows as a medium-sized, summer green tree. It reaches freestanding growth heights of up to 20 meters, in the high forest occasionally over 30 meters, and can reach stem diameters of over 100 centimeters as a freestanding single tree. Individual specimens of the Speierling can reach an age of up to 400 years, but in Central Europe usually significantly less. The spearling forms a deep-reaching heart root system.

The bark is rough. The spearling soon forms a cracked, small-scale, relatively dark grey-brown bark similar to that of a pear tree.

The comparatively large, often sticky winter buds are dull egg-shaped. They have a few roof tile-like overlapping, green shining, more or less bare, brown-edged bud sheds.

Sheet
The foliage leaves arranged alternately and spirally on the branches are divided into leaf stem and leaf spread. The leaf stem is 3 to 5 centimeters long. The leaf spread up to 25 centimeters long and about 10 centimeters wide is unpaired feathered. On the Blattrhachis, there are thus 13 to 17, rarely up to 21, leaflets with six to eight, rarely up to ten, opposite pairs; This is the lowest number within the genus Sorbus (in Europe). The leaflets are almost sedentary except for the final leaf, this is more or less stalked. The approximately equal-sized flakes are elongated at a length of 3 to 5 centimeters and a width of 1 to 1.5 centimeters, with a pointed upper end. The edges of the leaflets are sharply sawn in the upper area and almost all-round in the lower third. At the top they have teeth with an early falling gland. The leaf spread is initially fluffy, woolly haired and later calving. There is a plumage nerve, with 12 to 15 side nerves on each side of the main nerve. The base of the sheets is uniformly rounded. The auxiliary blades on the cross drive are obsolete.

Flowering

The flowering period is at the end of full spring in May to June after the arbor unfolding. 35 to 75, rarely up to 80 flowers stand together in terminal, umbrella inflorescences.

The pleasantly fragrant, twilight flowers are radiarly symmetrical at a diameter of 16 to 18 millimeters and five-fold with double
