Stem green, erect or arching. Prickles uniform, scattered, stout, hooked. 
Leaflets 5-7, small, oblong, acute, doubly serrated, glabrous or nearly so above, 
glandular all over and slightly pubescent beneath ; petioles glandular and pubescent ; 
stipules adnate, gland-ciliated, with small, ovate, acute, free tips. Flowers 1-3 ; 
peduncles setose and aciculate ; bracts small, ovate, gland-ciliated. Calyx-tube 
ampullaeform, usually naked ; lobes f in. long, leaf-pointed, glandular on the back, 
the outer slightly compound. Petals small, pink. Styles free, naked, often shortly 
exserted. Fruit oblong or urceolate, red, pulpy, ripening in October or the end of 
September ; sepals deciduous. 
Rosa micrantha differs from the ordinary Sweet Briar by its less 
compact habit, uniform prickles, less numerous leaves, smaller pale 
flowers, pointed leaflets, deciduous sepals, and oblong or urceolate, not 
pear-shaped, fruit. In habit it much resembles Rosa canina , and when 
seen growing in the hedgerows may easily be taken for that species. 
Its nearest relationship is with the Rosa Eglantei'ia of Linnaeus, the 
461
