derry’s park, in the county of Down, in Ireland, in about the
year 1815, and has ever since been cultivated in gardens,
and even occasionally raised as a crop for feeding cattle. It
rarely flowers, and, although usually reproduced from seed,
does sometimes thus produce young plants similar to the
type of the species. Its flowers spring from the summit of the
young shoots, are smaller than and differ slightly in proportion
from those of the true U. europatus. Its spines also are much
less rigid. But its remarkable appearance is caused by its
erect, close manner of growth.
The specimens figured were gathered in the Botanic Garden
at Cambridge, on May 30, 1849.— C. B.
