[From "Scots Roses And Related Cultivars Of Rosa Spinosissima", by Peter A. Boyd, pp. 9-17]
However, one would hope that a cultivar name such as ‘Andrewsii’ is applied to a one particular cultivar! This is not the case and ‘Andrewsii’ is applied to several different pale pink or dark pink cultivars with different degrees of doubling and different flower form.

No. 89. Rosa spinosissima, var. Andrewsii.
Rosa spinosissima, var. Andrewsii: a formis minoribus typicis recedit floribus paulum plenis, rubris.
This very pretty little Rose is the form of Rosa spinosissima most generally met with in old French gardens. Sometimes it occurs in hedges parting off flowers from vegetables, sometimes in isolated bushes, and it is rarely absent from the village cure's garden. Its power of renewing itself under any conditions of neglect and starvation accounts for its being still with us whilst many of the other Scotch Roses, at one time so plentiful, have long since disappeared. Andrews has nine plates of Scotch Roses, and his Rosa spinosissima nana, one of the three forms on plate 123, is evidently intended for the present Rose, although it is never actually so vivid in colour as in his drawing. Miss Lawrance has two drawings of single red forms of Rosa spinosissima and her plate 15 represents a very pretty variegated form which may be the Rosa nova variegata of Du Pont referred to by Thory (1. Gym Ros. p 14, 1813). Redoute's Grande Pimprenelle aux Cent-Ecus is described by Thory as resembling Du Pont's Rose, but finer and more beautiful in every respect; (2. Roses, vol ii, p 103. 1821) it has long disappeared from cultivation. These are but a few out of the large number of varieties to which hybrids of Rosa spinosissima have given rise, for in the space available it has only been possible to mention some of the more notable among them.
