ROSE TRIBE. 175 



awns, on ail enlarged, fleshy receptacle. (Name from 

 the Latin fragum, a Strawberry, and that from fragrans, 

 fragrant.) 



10. KUBUS (Bramble). Calyx 5-cleft ; petals 5 ; fruit 

 an assemblage of small drupes, arranged on and around 

 a spongy receptacle. (Name from the Latin ruber, red.) 



11. AGRIMONIA (Agrimony). Calyx 5-cleft, top- 

 shaped, covered with hooked bristles ; petals 5 ; stamens 

 about 15 ; seeds 2, enclosed in the tube of the hardened 

 calyx. (Name of Greek origin.) 



Sub-order IV. SANGUISORBID.E. The Burnet Group. 



The plants of this group would seem at first sight to 

 be scarcely connected with those already described. It 

 will, however, be found, on a close examination, that in 

 many important respects they agree with the characters 

 given in the description of the Order KOSACE^:, though 

 in others scarcely less important they appear to differ ; 

 these are the absence of petals, and the hardened calyx 

 of the fruit containing 1 or 2 nut-like seeds. The calyx 

 is 3 8 cleft, and the stamens are usually few in num- 

 ber. The plants are either herbaceous or shrubby, and, 

 like those of the last group, their properties are astrin- 

 gent, or tonic. In some species the flowers grow in 

 round or oblong heads. 



12. ALCHEMILLA (Lady's Mantle). Calyx 8-cleft, in 

 2 rows, the outer divisions smaller ; petals ; stamens 

 1 4, opposite the smaller divisions of the calyx ; seeds 

 1 or 2, enclosed in the hardened calyx. (Name from its 

 pretended value in Alchemy.) 



13. SANGUISORBA (Burnet). Calyx 4-cleft, coloured 

 (not green), with 2 4 scale-like bracts at the base ; 

 petals y stamens 4 ; seeds 1 or 2, enclosed in the tube 

 of the hardened calyx. (Name from the Latin sanguis, 

 blood, and sorbeo, to staunch, from, the supposed virtues 

 of the plant.)
