HOSA.] ROSACES. 123 



Thickets, hedges, &c. ascending to 1,350 ft. in Yorkshire ; fl. June-Aug. 

 Of the above characters, most disappear in one or other of the following 29 

 varieties, which Mr. Baker has systematized with great skill. In its common 

 form, this is the largest and freest growing of British roses, and may be 

 distinguished from spinosissima by the hooked prickles and habit, from 

 villosa by being more glabrous, from rubif/inosa by being eglandular, and 

 from arvensis by the free styles. DISTRIB. Europe, N. Africa, Siberia. 



SERIES 1. Ecristat'ae. Leaves eglandular beneath. Sepals reflexed after 



the fall of the petals, deciduous before the fruit (which ripens late) changes 



colour. 



* Leaves glabrous on both surfaces. Peduncles not fcistly. 



VAR. 1, lutetia'na, Leman (sp. ); 10-12 ft., leaflets about 7 green or glaucous, 

 terminal obovate, serratures simple, flowers 1-4 pink 2 in. diam., sepals 

 naked. Abundant. VAR. 2, surculo'sa, Woods (sp.) ; robust, flowers 10-30, 

 leaflets flat rounded at the base, teeth open. VAR. 3, splue'rica, Gren.

 fin. diam., styles villous. VAR. 4, sentico'sa, Ach. (sp.); slender, flexuous, 

 leaflets 1 in., teeth acute, fruit small globose. VAR. 5, duma'lis, Bechst. 

 (sp.); petiole glandular, stipules and sepals more densely gland-ciliated, 

 leaflets doubly-serrate. R. sarmenta'cea, Sm. ; y/aitcophylla, Winch. Very 

 common. VAR. 6, bise/rata, Herat (sp.); quite like TAB. 5, but serratures 

 more open and very compound, petioles very glandular. R. vina'cea, Baker, 

 has leaflets and bracts narrow acute, and fruit oblong. 

 ** Leaven glabrous above, hairy on the nerves beneath. Peduncles not bristly. 



VAR. 7, ur'bica, Leman (sp.); like lutetiana, but leaves pilose below and

 />latypkyl/a, Rau. VAR. 8, Jrondo'sa, Steven (sp.); leaflets smaller flatter 

 ovate-oblong more rounded at the base, fruit smaller globose. R. dumtt- 

 tni'iim, Woods. VAR. 9, arvatica, Baker ; like urbica, but leaves doubly- 

 serrate, fruit ovoid. Common in the N. of England. 



*** Leaflets more or less hairy on both surfaces. Peduncles not bristly. 



VAR. 10, dumeto'rum, Thuill. (sp.); leaflets green terminal often large thinly 

 hairy above softly below simply-serrate, fruit large ovoid, styles villous. 

 R. uncinel'/a, Besser. VAR. 11, prwino'sa, Baker; leaflets glaucous doubly- 

 serrate, petioles glandular. R. ccesia, Borrer. VAR. 12, incafna, Woods (sp.);

 hairy below doubly serrate, petioles prickly, peduncles very short, flowers 

 small white, fruit small short. R. inodora,, Hook. Fl. Lond. 

 **** Peduncles more or less bristly and glandular. 



VAR. 14, Andevagen'sis, Bast, (sp.), is lutetiana with bristly peduncles. S. of 

 England, rarer in theN. and Scotland. VAR. 15, rerticillacan'tha, Herat, is. 

 r'>'ni.l is \vifh ditto. Not uncommon. VAH. 16, colli'na, Jacq. (sp.), is urlrim 

 with ditto. Surrey and Devonshire. VAH. 17, cce'sia, Smith (sp.) ; near
