   • 1982, Dansk dendrologisk årsskrift:

     Den eneste barriere mod hybridisering mellem vore tre hjemhørende tjørne er således tilsyneladende kun af økologisk-bestøvningsbiologisk art (Bradshaw, 1975 og Byatt, 1975 b).

     Thus, the only barrier towards hybridization of our three indigenous hawthorns appears to be of an ecological-pollination-biological type (Bradshaw, 1975 and Bytt, 1975 b).

   • 1991, Løveridderen, Museum Tusculanum Press, →ISBN, page 6:

     Jeg drejede til højre gennem en tyk skov; vejen var slem, fuld af brombærkrat og tjørne.

     I turned right through a thick forest; the path was bad, full of blackberry shrubs and hawthorns.

   • 1970, Danske studier:

     Siversted [Sydslesvig] ses her og der ensomme tjørne vokse ikke alene i et skel, men også inde på marken; disse tjørne ryddes eller fældes ikke.

     In Sieverstedt [Southern Schleswig], here and there may be seen solitary hawthorns growing not only in the boundaries between fields, but also on the field itself; these hawthorns are not cleared or chopped down.
