Rosa Involuta
On the authority of Sir Joseph Hooker R. involuta forms one of the seven British species, and therefore claims a brief notice here. It appears that its name is derived from the form of the petals, which are involute. Discovered by Dr. Walker on the Scottish Highlands ; also found on banks and in hedges of the Orkneys, and in Ireland. In growth it makes a compact reddish-grey bush between 2 and 3 feet high. The branches are erect, somewhat single, and very strong, having a cracked bark densely covered with prickles. The leaves are glandular or hairy on both sides, and when bruised emit a turpentine smell. The flowers, produced singly, are variable in colour, both red and white. The tube of the calyx and the sepals bristle all over with setae and clammy glands. The fruit, produced sparingly, is red, and stands erect.  R. involuta forms a link between villosa and spinosissima.
