This tree is 25M east of the bridge growing on the stream bank in poor soil. In September 2015, inside each of two haws opened was a single ovoid light brown seed approximately 6mm x 8mm. Thorns were very sparse. In May 2016 the flowers measured about 16mm across and leaves 5 to 6cm long.

The following table gives the approximate physical measurements of examined haws together with the number of pips found within them.

Diameter mm Length mm No. of pips
11 14 1
11.5 14 1
11.5 12.5 1
11.5 11 1
11.5 12.5 1

Measurements were taken in late October 2020. Length measurement was for main body of the fruit and did not include the peduncle. No thorns were seen on the tree.

General tree description

Crataegus monogyna is a native tree, often planted as hedging. It can grow to 15 metres and has a spreading and untidy shape. Its bark is dark orange-brown or pink-brown, narrowly cracked into rectangles. The leaves are up to 6cm long, deeply cut, with lobes toothed at the tips. White, fragrant flowers come in clusters in late spring. Red fruits (haws) appear in autumn. They contain a single pip.
