R. rugosa 'Acicularis'               before 1880
'A very vigorous and altogether distinct plant of rather erect habit, often making small shoots six feet long; they are densely spiny, the single flowers intense lake crimson; the fruit somewhat pear-shaped and slightly hairy.'
'This originally came from Japan and has been in my possession quite twenty years' (catalogue no. 32) according to Thomas Smith. It is not mentioned in current works.
Smith also offered 'acicularis seedling form' in subsequent catalogues (e.g. Newry roses no. 32: 9 (1898-1899); - no. 59: 30 (1903-1904).
