Bromopsis benekenii (Lange) Holub

Lesser hairy-brome

Status: scarce

This grass is apparently largely confined to woods on shallow chalk, limestone or other calcareous soils in steep valleys. It is frequently recorded in beech woods but also occurs in other deciduous woods, and woodland margins and scrub. It grows in small to medium-sized patches among the species-rich ground layer on moderate humus in light shade and grows best on a slight slope.

B. benekenii is a perennial species which grows in small tufts. Little is known of its reproductive biology.

This is a little known and probably under-recorded species. It is treated by some authorities as B. ramosa subsp. benekenii (Lange). Tzvelev, and several competent recorders have found it difficult to distinguish from B. ramosa, with which it sometimes grows. B. benekenii may therefore still be present in the areas for which only pre-1970 records are available.

It is found in central and eastern Europe and at scattered localities eastwards to the Yangtze River in China.
