Bromus bromoideus, the brome of the Ardennes, is an annual grass once found only as a weed in spelt fields in southern Belgium and northern France, now known mainly from preserved seed. It is probably a variant of Bromus secalinus, and growing it means working from seed and mimicking the arable conditions it evolved in.

About
Bromus bromoideus, the brome of the Ardennes, is a species of grass in the genus Bromus. Genetic studies suggest that it rather should be regarded as a variant of Bromus secalinus.
It was found in the calcareous meadows of the provinces of Liège and Luxembourg in Belgium, notably around the towns of Rochefort, Beauraing and Comblain-au-Pont, where it was first discovered in 1821. It was thought to be extinct since the 1930s until preserved seeds were rediscovered in collections of the Belgian National Botanic Garden by the English botanist David Aplin and as a result of the publicity, seeds in other locations came to light in 2005.
Where it grows
Bromus bromoideus was endemic to a limited geographical area spanning southern Belgium and northern France. Unlike many plant species, B. bromoideus had no known natural habitat outside of agricultural settings. It was exclusively found in cultivated fields, primarily those used for growing spelt (Triticum spelta), a hulled wheat variety that was once widely cultivated in the region.
