Burnet. Including Sanguisorba. ORD. Rosacee. A genus 
comprising about fifteen or twenty species of greenhouse 
or hardy, perennial (in one case annual) herbs, decumbent 
at base, very rarely spiny shrubs, inhabiting the whole of 
the temperate and warmer regions of the Northern hemi- 
sphere. Flowers at the tips of the scapes, densely capitate 
or spicate, small, bracteate and bibracteolate ; calyx tube 
turbinate, persistent, constricted at throat; lobes four, 
petal-like, deciduous, imbricated; petals absent. Leaves 
alternate, impari-pinnate ; petioles*elongated, with an im- 
bricated sheath at base; leaflets petiolulate, serrated, 
rarely entire, The herbaceous kinds thrive in any ordinary 
garden soil, and may be increased by seeds. 
require a light, rich soil, and may be propagated by young 
cuttings, which will root readily under a glass. See also
