208 THE JOURNAL OF BOTANY 



11. R. Woodsiana. R. tomentosa Sm. var. Woodriana Groves in 

 Bot. Exchange Club Eep. 1880, 30 (1881). Bush erect, compact; 

 main thorns uncinate ; leaves oval, slightly hairy on both surfaces, 

 serration open, subfoliar glands few ; peduncles densely glandular - 

 aciculate ; petals pale rose ; fruit ellipsoid, ripening in September. 

 Very near R. uncinata, to which it might perhaps be united as a 



variety. 



Wimbledon Common, Surrey, Groves. 



12. R. scabriuscula Sm. Eng. Bot. 1. 1896 (1808). R. tomentosa 

 Sm. var. scabriuscula Baker in Trans. Linn. Soc.xi. 217 (1869). Bush 

 tall, arching ; thorns long, narrow, slightly falcate ; leaflets long- 

 ovate-elliptic or elliptic-obovate, deeply, sharply, doubly serrate, 

 green on both surfaces, slightly hairy, subfoliar glands few; peduncles 

 long, glandular-aciculate ; calyx-tube aciculate or naked ; sepals 

 subpinnate, long-appendiculate ; uncertain in direction, slightly 

 ascending after flowering or reflexed from the first, always deciduous 

 before the fruit changes colour ; petals light rose ; clusters often 6 or 

 more flowered ; fruit ovoid, sometimes prolonged, ripening in October. 



Abundant and of general distribution in England, Scotland, 

 and Ireland ; more common southwards. Sutherland, Bettyhill,

(Muckross) ! A glabrous form of this rose occurs : Carnarvon, 

 Linton \ West Yorks, Dent Dale. 



Another specialized form of this plant occurs at the Menai 

 Straits, Carnarvon, very robust, with glandular aciculate petioles, 

 large often simply serrate glabrescent leaflets, and partly sub- 

 persistent and suberect sepals. This plant has been attributed to 

 R. britannica Deseg., from which however it is very different. It 



probably owes its peculiarities to its robustness, joined with its 

 maritime situation. 



13. E. sylvestris Lindl. Syn. Brit. Fl. 101 (1829). R. tomen- 

 tosa Sm. var. si/lvestris Woods in Trans. Linn. Soc. xii. 202 (1817). 

 Habit less tall than in R. scabriuscula ; thorns stouter, falcate ; 

 leaves oval-elliptic, slightly hairy, green on both surfaces, subfoliar 

 glands numerous ; peduncles and clusters of flower as in R. scabri- 

 uscula; sepals subpinnate, shortly appendiculate, reflexed from the 

 first, caducous ; fruit ovoid or urceolate, ripening in October. 



Distribution as R. scabriuscula, but less abundant. S. Devon ! 

 Kent! Cheshire! Roxburgh! East Inverness ! Mayo!, Ireland. 



14. R. tomentosa Sm. Fl. Brit. ii. 539 (1800) (ex parte). Bush 



arching, flexuose ; main thorns long, falcate, becoming smaller and 



straighter on the flowering-shoots ; leaves normally softly hairy on 



both surfaces ; subfoliar glands ; peduncles long, glandular 



aciculate ; flowers up to 6 or more in a cluster ; sepals ovate 



flattish, the main ones often strongly pinnate ; reflexed from the 



first, and falling before the fruit changes colour; fruit small, 



normally ovate, at times subrotund or shortly urceolate, ripening 

 in October. 



As defined above, an easily recognizable and tolerably constant 

 rose.
