doubly serrate glabrous on both sides or hairy beneath, sep. re- 

 flexed deciduous pinnate, fr. ovate-urceolate or roundish, disk 

 flat. — St. erect, with long arching branches. L. flat or keeled, 

 rarely a few glands on the veins. Fl. few ; rarely the sep. are 

 subpersistent and ascending ; ped. mostly naked ; styles distinct, 

 hairy.— Hedges and thickets. Sh. VI.'VII. E.S.I.

 rolla. — * L. glabrous on hoth sides; ped. without bristles. — It. 

 canina (Woods) ; Its. elliptic flat simply serrate green or grey, 

 fr. urceolate. E. B. 992. — R. surculosa (Woods) ; Its. rounded 

 flat simply serrate green or grey. — R. spharica (Gren.) ; Its. 

 rounded below (flat ?) simply serrate, bright green, fr. globose. 

 — R. sarmentacea (Woods) ; Its. roundish or elliptic keeled 

 doubly serrate. E. B. S. 2595. R. dumalis and R. biserrata 

 Baker. — ** L. naked above, hairy on the veins beneath, ped. without 

 bristles. — R. Forsteri (Sm.) ; Its. rounded below usually simply

 doubly serrate. E.B. 2867. — R. tomentella (Lem.) ; Its rounded 

 below doubly serrate very hairy beneath, fr. subglobose. — Forms 

 of most of the above with more or less prickly and setose pedun- 

 cles have been named but scarcely deserve notice. — ^. R. mon- 

 iicola (Rap.) ; Its. without gla,nds beneath, sep. ascending after 

 fall of corolla subpersistent. — R. coriifolia (Fr.) ; Its. usually 

 simply {R. bructescens, Woods) sometimes (R. Watsoni, Bak.) 

 doubly serrate. — Other slightly varying forms are named. — y. 

 R. Borreri (Woods) ; Its. glandular only on the veins beneath, 

 the surface naked. R. dumetorum E. B. 2579, -B. Bakeri 

 (Deseg.) Sy. E. B. 473, and R. marginata (Wallr.) seem hardly 

 to differ from R. Bor7-eri which itself is not easily distinguish- 

 able fi-om R. tomentosa.
