Shrub; prickles and pricklets as a rule very abundant, approximate, often very few (some specimens unarmed); leaflets 5—11, often 7, 10— 24 mm long, orbicular, twice as long as broad, glandular, at least along midrib beneath, teeth (rarely only partly) compound -glandular, 8—16 at each side; pedicels 10—30 mm long, smooth or more or less prickly and glandular, resembling the often hispid hypanthium; sepals 8—13 mm long, dorsally more or less glandular or acicular -glandular; corolla white, 30— 50 mm in diameter; fruit globose or slightly broader than long, 8—13 mm long. June-July.
European part: Crim. (mainly in the Yaila Mountains, but also found near Bakhchisarai); Caucasus: W., E. and S. Transc. Gen. distr.: Med. Described from S. France (vicinity of Montpellier). Type in Geneva.
Note . In the districts of Ai-Petri and Kokkoz, there are often encountered less typical forms, with glands confined to midrib and teeth only, partially bidentate (entire teeth prevail). Similar intermediate forms also grow in other localities; one of these, R.rupincola Fisch. ex Sweet, Hort, Brit. ed. II (1830) 180, is widely distributed in W. Siberia, where R. myriacantha does not grow. Generally speaking, like the whole series Spinosissimae, forms of the type R. myriacantha also require special study. For the present, it should be pointed out that forms identical with the authentic R. myriacantha DC. from Montpellier are apparently not encountered in the USSR; Bieberstein named the ordinary Crimean form in schedis R.polyacantha M.B., but by the rules of nomenclature this name is disqualified.

R. spinosissima, Scotch Rose, Burnet Rose. - (Spinosissima means very spiny). Very hardy at Edmonton. Low-growing, to about 3 feet. Flowering branchlets prickly and bristly. Leaflets appear early, dense, small, 5-9, somewhat reddish in autumn. Flowers white, pink or reddish, sometimes yellow, fragrant, often semi-double, late June. Fruit black. Perhaps has been overlooked too much in shrubbery plantings. At Beaverlodge, the Scotch Rose is not fully hardy but is one of the most satisfactory of the ornamental shrub roses; the Burnet planted in 1934 has done well and is considered one of the best.
Some R. spinosissima hybrids and varieties, likely hardy at Edmontton, are: Berwick (semi-double, deep rose); Bicolor nana (creamy-white, dwarf); Brightness (double crimson purple); Dundea (lilac -rose, white reverse); Flavoscans (semi-double, lemon); Globe (semi-double, deep rose); Lady Hamilton (semi-double, creamy-white); Lismore (double, blush); Staffa (double, white); Townsend (double, pink).
