 Key to Groups and Subgroups. 



' Straight-stemmed, low-growing bushes ; sepals persistent till decay 

 of fruit ; prickles straight ; upper stipules on flowering branches 



with incurved auricles ; stj'les villous 2 



Habit intermediate ; sepals erect and persistent till fruit ripens ; 

 prickles straight or falcate; auricles straight ; styles usually villous 



GEOUP OMISSA (t) 



Stems flexuose, often tall and arching ; sepals spreading or reflexed, 



deciduous before fruit ripens ; prickles falcate or uncinate, more 



rarely straight ; auricles straight ; styles hispid or glabrous, rarely 



villous 3

r. Subgroup Pomifeeje. (See p. 38.) 



Leaflets 2 in. long, glandular beneath, very parallel-sided, thin ; 

 prickles subequal ; armature of peduncles and fruit stout

("Fruit normally globose or broadly ovoid; leaflets quite eglandular; 



.J prickles more or less curved Sherardi.
