» A REVISED AIMIAXUEMENT nF BIUTISII EOSER 



without subfoliar glands. Their peduncles are smooth. The stipules, 

 bracts and sepal edges, sometimes also their backs, show a greater 

 tendency to develop glands than those of the two preceding Subgroups. 

 Very compound gland-tipped biserration sometimes occurs, but tliis 

 is a feature of the Scahratce, which have, normall}^ at least, subfoliar 

 glands. 



The Subgroup may have been too much subdivided, but its 

 varieties are still very comjjrehensive and ill-detined. 



R. LUTETiAXA var, dumalis (Bechst.). The counterpart of i?. 7«r- 

 tetiana but with more or less biserrate leaHets, the fruit is usually 

 ovoid or ellipsoid and the stvles hispid, rarely denselv so or subglabrous. 

 V.c. 3, 5, 14, 17, 22, 23, 32, 33, 34, 36, 55, 57, 58, 02, 69, 78, 96, 

 Deny, Antrim. 



f. ruheUlJlora (liip.). I see nothing in this but a bright red 

 flowered form of the variety, llijmrt credits it with fewer and 

 straighter prickles, subsessile lateral leaflets and broad sti^^ules. 

 V.c. 3, 17, 33 or 34 ?, 57, 58, iS^ ?. 



Var. spliceroidea (Kip.). This differs from vars. glohularis and 

 S][)li(Brica only in its biserrate leaflets. The sepals, as in those 

 varieties, show a tendencj'^ to spread. V.c. 3, 8, 17, 34 ?, 36, 58, 67, 

 Antrim, Down. 



Var. hiserrata (Mer.). Leaflets of medium size, more strongly 

 biserrate than in var. dumalis, fruit subgiobose, and styles woolly. 

 It is usually a more glandular plant, and has a tendency to spreading 

 or even suberect sepals. V.c. 3?, 36, 40, 41, 42, 64, 69, 70, Perth, 

 Down. 



Var. eriosfyla (Kip.). Ver^'' near the last, but a smaller bush 

 with smaller fruit, sepals quite reflexed, and more exserted styles. 

 V.c. 3 ?, 5, 31, 32 ?, 33 ?, 49 or 52, 70, 93, Down. 



Var. viridicata (Pug.) is a comprehensive and ill-defined variety. 

 It has rather small or medium-sized leaflets, not luuch biserrate, 

 therefore not easily separable from varieties of the last Subgroup. 

 Its styles are rather long and densely hispid, the fruit small, sub- 

 globose or broadly ovoid. V.c. 3, 14, 17, 21, 32, 34, 36, 37, 42, 5b, 

 57, 58, 59 ?, 69, 70, Antrim, Down. 



Var. leiostyla (Rip.)=i?. Ghahoissm Gren. ? Like var. dumalis 

 but with smaller leaflets and glabrous styles, often in a column. 

 V.c. 3, 11 ?, 14, 17, 32, 49 or 52, 58, 62. 



f. glaherrima (Dum.) differs from the last mainl}^ in its sub- 

 globose or broadly ovoid fruit. Large leaflets, few prickles and white 

 flowers are also assigned to it. V.c. 17, 40, 58. 



Var. Cariofi (Chab.). Leaflets small or rather small but broad, 

 like those of B. tomentella, normally very prickly, but not always so, 

 flowers white, fruit ovoid or urceolate, and stvles glabrous. V.c. 3, 

 17, 36, 58, 67 ?. 



Var. stenoca7ya (Desegl.). Near var. Carioti, but leaflets and 

 fruit much narrower, flowers rose and st3des glabrous or subglabrous. 

 It is said to be less prickly. V.c. 3, 17, 23, 31, 32, 36, 55, 57, 58. 



Var. adscifa (Desegl.). Leaflets small, fruit ovoid or ellipsoid, 

 styles hispid, protruded from a conical disc, flowers white and many 

 hooked prickles ai'e its main features. V.c. 13, 17, 36, 40, 58, ijo, 70.
