The tetradium daniellii ( Tetradium daniellii ), also bee tree , honey ash , Fragrant diamond or thousand flowering shrub called, is a plant of the genus tetradium ( Tetradium ) in the family of Rutaceae (Rutaceae).
description
The velvety stinky ash grows as a deciduous shrub or tree and can reach heights of up to 20 meters. The bark of the trunk is smooth and gray; it thus resembles the bark of the common beech .
The opposite, imparipinnate leaves are 15 to 44 centimeters long. The five to nine, sometimes eleven leaflets are broadly ovate to lanceolate, sometimes also elliptical. The leaflets are glossy dark green on top and duller on the underside. The base of the leaflet is narrowly wedge-shaped or rather truncated or rounded. The leaflets taper to a point. The leaflets are about 5 to 18 inches long and 3 to 10 inches wide. The leaves turn a little yellow-green in autumn before they fall off.
The flowering period extends from June to August. The inflorescences are about 3.5 to 19 centimeters in size. The velvety stinky ash is dioeciously segregated ( diocesan ). The unisexual flowers are fivefold, sometimes fourfold. The small sepals that are fused at their base are 0.5 to 1.5 mm in size. The white to pale brown petals are 3 to 5 millimeters in size. There is a discus. The male flowers contain only a circle with four or five fertile stamens , they are about one and a half times as long as the petals. In the female flower four to five are carpels to ovary grown, the hairy between the carpels. There are two ovules per carpel .
Usually five common follicles are fused at their base; they ripen from August to November. The round, black seeds are about 2 to 4 millimeters in size.
The number of chromosomes is 2n = 76 or 2n = 78.
Distribution and location
The velvety stinky ash is native to northern China and Korea . Its Chinese distribution area extends over the provinces of Anhui , Gansu , Hubei , Hunan , Shaanxi and Shandong . It is found at altitudes from sea level up to 3200 m, especially in forests and on the edges of forests.
In Central Europe , the velvety stinky ash is hardy and is mainly planted as a bee pasture .
Surname
The flower umbels smell pleasant, while the grated leaves of stinky ash give off an intense odor. This is where the apparently contradicting names of the tree as fragrant or smelly ash stem from.
Systematics
The species was described by the English botanist John Joseph Bennett in 1862 under the taxon Zanthoxylum daniellii . His compatriot William Botting Hemsley referred to this description in 1886, but classified the species under the taxon Euodia daniellii (Benn.) Hemsley in the genus Euodia . The species is still well known under this long-standing taxon; It was not until 1981 that it was incorporated into the genus Tetradium by the American botanist Thomas Gordon Hartley under the current taxon Tetradium daniellii .
There are many other synonyms for the species; here is a selection:
- Ampacus danielli (Benn.) Kuntze
- Euodia baberi Rehder & EHWilson
- Euodia delavayi Dode

The species epithet daniellii was chosen in honor of the botanically interested British military doctor William Freeman Daniell (1818-1865).
