X Hulthemosa Juz. nov. gen. hybr. In Addenda IX, 480.
Plant similar in all parts to Rosa but stipules resembling leaflets, sometimes adnate to leaflets of lower pair.
Note . The following two forms appear to be hybrids between Hulthemia persica and species of Rosa; this hybrid nature of the "genus" is reflected in its name.

margined, with divergent ovate -lanceolate auricles. Flowers often solitary, rarely 2—3, 3—6 cm in diameter, on long, smooth, sometimes glandular - bristly, 0.7—3.5 cm long pedicels; hypanthia elliptic, ovoid or pyriform, rarely globose; sepals lanceolate, narrow, more or less broadened distally, often foliate, dor sally smooth or glandular, directed upward after anthesis, persistent; petals obcordate, pink or reddish; styles villous, free, head orbicular, woolly; fruits usually drooping, sometimes erect, 1.5—2.5 cm in diameter, red, sometimes ovoid with apical constriction, sometimes ellipsoid, tapering at both ends, sometimes oblong, often obovate -pyriform, strongly tapering at base, crowned with convergent sepals.

Scand., N. Mong., N. Ch., Jap., N. Am. Described from Siberia. Type in London.
Economic importance. Ornamental, often grown in the gardens of Siberia; also forms part of hedges. Roots and leaves contain tannins. The yield of essential oils from the flowers is 0.04% of dry weight (Hammerman). The fruit contains sugar, tannic and dye substances, pectin, pentosan, vitamin C (ca. 2.30% ascorbic acid per dry weight of pulp) and Q' yields an orange dye upon boiling
Note. A highly variable species which may require further division; such forms as R.gmelini Bge. and R, carelica Fr., at one time considered as separate species, scarcely deserve special attention. Of much greater interest are some of the Far Eastern forms studied by Crepin. Crepin wrote (l. c. 1875, 6) that at one time in the Berlin herbarium he had given the name R. discolor Crep. to a form collected by Maksimovich in Manchuria along the Amur River; this form, also collected by Glehn, had been seen by Crepin in the herbarium of the Academy of Sciences, St. Petersburg. He gave the name of R. amurensis Crep to another form in the Berlin herbarium also collected by Maksimovich. Both these forms, however, still await study.

R.amblyotis C. A. M. in Mem. Acad. Sc. St. Petersb. ser. VI, t. VI (1849) 30; Crep. in Bull. Soc. Bot. Belg. XIV (1875) 38; Kom., Fl. Kamtsch. II, 268. - R. camtschatica Cham, in Linnaea VI (l83l) 590, non Vent.- R. davurica Hulten, Fl. of Kamtch. Ill (1929) 89, non Pall.
Shrub; stipulate prickles on flower -bearing branches subulate, usually erect, with ascending mucro (prickles sometimes absent); stipules very thin, scarious, very obtuse; leaflets broader than in R. davurica, pubescent beneath and very often glandular (like R. davurica); bracts of the same
character as stipules, broader than in R. davurica. In all other parts similar to R. davurica Pall. Presumably the eastern race of R. davurica . June— July .

Meadows, shrubby formations and birch forests.— Far East: Kamch., Sakh. Endemic? (in the Aleutians, the most closely related form is R.aleutensis Crep.). Described from Kamchatka (near Petropavlovsk, Tagil River, and between Kharchinsk and Shivelyuch). Type and paratype in Leningrad.
Economic importance. According to Schrenk, in Sakhalin the fruit is stored up for the winter to be used in the preparation of a special kind of food (reminiscent of cereal processed; the thawed-out fruit is ground up and mixed with fish oil.
Note. Hulten (l. c, p.90— 9l) conjectures that the material from which C. A. Meyer established this species may have comprised the hybrid R. davurica X R.rugosa, common in Petropavlovsk. If so, Meyer's view that his species was "inter R.cinnamomeam et R.rugosam media" may indeed be correct.
